SECRff SECTION 1

U) LUNAR RE-ENTRY VEHICLE

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

SECRff coeifirient CL for any given angle of attack and a second class

with a variable-geometry configuration Fixed CL designs have

been tested in ihe US however the variable -geometry concept

has not received any appreciable study One such variable-geomshy

etry design calls for folded wing$ on the leeward side of a

relatively compact vehicle Aiter the vehicle has slowed down and

reached a low altitude the wings are unfolded to provide control

and stability required for a soft landing (81

In the design opound a vehicle which re middotenters the atrnogphere

from the moon it is assumed that the objective of re-entry is to

arrive at a particular point on the earth1 s surface If it has no

guidance system the vehicle will depend entirely on the forces that

act upon it during its precalculated trajectory Thue it may be

best that the vehicle has no lift since unexpected variations in

auch parameters as density and wind velocity will more severely

affect the trajectory of a lifting vehicle than they wbullll oi a bilistbull ~

(S1 USSR LUNAR RECOVERY SITE SELECTION

Pnor to asses Bing the op~ratioral characteristics of a land

a1middotea recovery range for returning Soviet lunar exploration

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

elements involved and velocity requil-ed to achieve the proper

trajectory Assuming that the prelaunch calculations can be

vehie can foil~middot middot lamp programmed trajectory an accurat~ error

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

SECRET AFMDC 63-3772

SECRET boundaries of the vehicle d1splacernent with respect to the calculated

landing site

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

The use of a semi-ballistic lunar re-entry vehicle (nominal

Lfo bull 5 would offer a mean re-entry corridor provide adequatel I

range accuracy and still incorporate design simplicity Assuming

that this type of re-entry vehicle wiU be chosen by the Soviets and

the opportunity lor unauthorized persons to locate and examine the

re~entry vehicle prior to exploitation by trained recovery forces

In order to accomplish this the recovery area should either be

j 11parsely populated or under continuous security control bull (8f

A review of current Soviet earth orbit recoveries indicates

-I that the re-entry corr idor lies between the longltudinal boundaries

of the Tyura Tam and Sary Shagan rangehead areas with impact

occurring just north of the range boundaries The Soviet range

areas lend themselves well to middotthe maintenance of tight security

during recovery operations without necessitating full-time security

personnel Due to the relatively low population density in the

area overshoots into the northern latitudes would require only

Soviets with a relatively lowcoat security for c~ when bull ~~deo

Use of Soviet missile test range areas for recovery

purposes would be well suited for such supervision cf personnel

Military and civilian personnel located in the proposed recovery

area could be alerted or removed during the recovery exercise

and all air I ground movement could be controlled fST

Population densities at latitudes under approximately

lifting type re-entry vehicle would require an expansive flat terrain

area suitable for an aerodynamic type land1ng This type of re-entry

would also require add1tional latbed areas for abort and overshoot

conditions The use of a semi-ballistic re-entry vehicle employing

parachute ltlrag devices would ideally also require a large flatbed

Since terrain surround ing the current recovery area is one

of the most suitable areas (if not the most) in the USSR for landing

and recovery it seems likely that this area would be projected for

use in a programmed lunar mission ~

The southern boundaries of the available rarge area would

probably be the 44degN latitude providing entry well within the USSR

The northern boundary would be restricted to an area generally

below 56degN latitude due to population densUy and higher elevation~

For a relatively high lift (LID ) I) lunar re-entry

both orbital corridor stations and the recovery site Continuous

tracking will be required from the deboost point to the impact

site which wi ll normally result in an initial need for at least

eight tracking stations along the orbital corridor This arrangeshy

The number of aircraft involved in the search activity is

dependent upon the precalculated impact accuTacy of the re-entry

U) LUNAR RE-ENTRY VEHICLE

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

with a variable-geometry configuration Fixed CL designs have

been tested in ihe US however the variable -geometry concept

has not received any appreciable study One such variable-geomshy

etry design calls for folded wing$ on the leeward side of a

relatively compact vehicle Aiter the vehicle has slowed down and

reached a low altitude the wings are unfolded to provide control

and stability required for a soft landing (81

In the design opound a vehicle which re middotenters the atrnogphere

from the moon it is assumed that the objective of re-entry is to

arrive at a particular point on the earth1 s surface If it has no

guidance system the vehicle will depend entirely on the forces that

act upon it during its precalculated trajectory Thue it may be

best that the vehicle has no lift since unexpected variations in

auch parameters as density and wind velocity will more severely

(S1 USSR LUNAR RECOVERY SITE SELECTION

Pnor to asses Bing the op~ratioral characteristics of a land

a1middotea recovery range for returning Soviet lunar exploration

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

elements involved and velocity requil-ed to achieve the proper

trajectory Assuming that the prelaunch calculations can be

vehie can foil~middot middot lamp programmed trajectory an accurat~ error

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

SECRET AFMDC 63-3772

SECRET boundaries of the vehicle d1splacernent with respect to the calculated

landing site

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

The use of a semi-ballistic lunar re-entry vehicle (nominal

Lfo bull 5 would offer a mean re-entry corridor provide adequatel I

range accuracy and still incorporate design simplicity Assuming

that this type of re-entry vehicle wiU be chosen by the Soviets and

the opportunity lor unauthorized persons to locate and examine the

In order to accomplish this the recovery area should either be

A review of current Soviet earth orbit recoveries indicates

-I that the re-entry corr idor lies between the longltudinal boundaries

of the Tyura Tam and Sary Shagan rangehead areas with impact

occurring just north of the range boundaries The Soviet range

areas lend themselves well to middotthe maintenance of tight security

during recovery operations without necessitating full-time security

personnel Due to the relatively low population density in the

area overshoots into the northern latitudes would require only

heavy forest treae and water areas should be avoided Use of a

lifting type re-entry vehicle would require an expansive flat terrain

area suitable for an aerodynamic type land1ng This type of re-entry

would also require add1tional latbed areas for abort and overshoot

conditions The use of a semi-ballistic re-entry vehicle employing

parachute ltlrag devices would ideally also require a large flatbed

Since terrain surround ing the current recovery area is one

of the most suitable areas (if not the most) in the USSR for landing

and recovery it seems likely that this area would be projected for

use in a programmed lunar mission ~

The southern boundaries of the available rarge area would

probably be the 44degN latitude providing entry well within the USSR

The northern boundary would be restricted to an area generally

below 56degN latitude due to population densUy and higher elevation~

U) LUNAR RE-ENTRY VEHICLE

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

Problems which affect the earth entry of a returning lunar

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

re-entry corridor and more maneuverability necessitates a more

SECRff SECTION 1

U) LUNAR RE-ENTRY VEHICLE

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

SECRff coeifirient CL for any given angle of attack and a second class

with a variable-geometry configuration Fixed CL designs have

been tested in ihe US however the variable -geometry concept

has not received any appreciable study One such variable-geomshy

etry design calls for folded wing$ on the leeward side of a

relatively compact vehicle Aiter the vehicle has slowed down and

reached a low altitude the wings are unfolded to provide control

and stability required for a soft landing (81

In the design opound a vehicle which re middotenters the atrnogphere

from the moon it is assumed that the objective of re-entry is to

arrive at a particular point on the earth1 s surface If it has no

guidance system the vehicle will depend entirely on the forces that

act upon it during its precalculated trajectory Thue it may be

best that the vehicle has no lift since unexpected variations in

auch parameters as density and wind velocity will more severely

affect the trajectory of a lifting vehicle than they wbullll oi a bilistbull ~

difficult to provide suitable lift because of the severity of heating

(S1 USSR LUNAR RECOVERY SITE SELECTION

Pnor to asses Bing the op~ratioral characteristics of a land

a1middotea recovery range for returning Soviet lunar exploration

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

elements involved and velocity requil-ed to achieve the proper

trajectory Assuming that the prelaunch calculations can be

vehie can foil~middot middot lamp programmed trajectory an accurat~ error

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

SECRET AFMDC 63-3772

SECRET boundaries of the vehicle d1splacernent with respect to the calculated

landing site

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

The use of a semi-ballistic lunar re-entry vehicle (nominal

Lfo bull 5 would offer a mean re-entry corridor provide adequatel I

range accuracy and still incorporate design simplicity Assuming

that this type of re-entry vehicle wiU be chosen by the Soviets and

the opportunity lor unauthorized persons to locate and examine the

re~entry vehicle prior to exploitation by trained recovery forces

In order to accomplish this the recovery area should either be

j 11parsely populated or under continuous security control bull (8f

A review of current Soviet earth orbit recoveries indicates

-I that the re-entry corr idor lies between the longltudinal boundaries

of the Tyura Tam and Sary Shagan rangehead areas with impact

occurring just north of the range boundaries The Soviet range

areas lend themselves well to middotthe maintenance of tight security

during recovery operations without necessitating full-time security

personnel Due to the relatively low population density in the

area overshoots into the northern latitudes would require only

Use of Soviet missile test range areas for recovery

purposes would be well suited for such supervision cf personnel

Military and civilian personnel located in the proposed recovery

area could be alerted or removed during the recovery exercise

and all air I ground movement could be controlled fST

Population densities at latitudes under approximately

heavy forest treae and water areas should be avoided Use of a

lifting type re-entry vehicle would require an expansive flat terrain

area suitable for an aerodynamic type land1ng This type of re-entry

would also require add1tional latbed areas for abort and overshoot

conditions The use of a semi-ballistic re-entry vehicle employing

parachute ltlrag devices would ideally also require a large flatbed

Since terrain surround ing the current recovery area is one

of the most suitable areas (if not the most) in the USSR for landing

and recovery it seems likely that this area would be projected for

use in a programmed lunar mission ~

The southern boundaries of the available rarge area would

probably be the 44degN latitude providing entry well within the USSR

The northern boundary would be restricted to an area generally

below 56degN latitude due to population densUy and higher elevation~

For a relatively high lift (LID ) I) lunar re-entry

vehicle the equipment requirements increase substantially for

both orbital corridor stations and the recovery site Continuous

tracking will be required from the deboost point to the impact

site which wi ll normally result in an initial need for at least

eight tracking stations along the orbital corridor This arrangeshy

The number of aircraft involved in the search activity is

dependent upon the precalculated impact accuTacy of the re-entry

U) LUNAR RE-ENTRY VEHICLE

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

SECRff coeifirient CL for any given angle of attack and a second class

with a variable-geometry configuration Fixed CL designs have

been tested in ihe US however the variable -geometry concept

has not received any appreciable study One such variable-geomshy

etry design calls for folded wing$ on the leeward side of a

relatively compact vehicle Aiter the vehicle has slowed down and

reached a low altitude the wings are unfolded to provide control

and stability required for a soft landing (81

In the design opound a vehicle which re middotenters the atrnogphere

from the moon it is assumed that the objective of re-entry is to

arrive at a particular point on the earth1 s surface If it has no

guidance system the vehicle will depend entirely on the forces that

act upon it during its precalculated trajectory Thue it may be

best that the vehicle has no lift since unexpected variations in

auch parameters as density and wind velocity will more severely

affect the trajectory of a lifting vehicle than they wbullll oi a bilistbull ~

Pnor to asses Bing the op~ratioral characteristics of a land

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

elements involved and velocity requil-ed to achieve the proper

trajectory Assuming that the prelaunch calculations can be

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

of the Tyura Tam and Sary Shagan rangehead areas with impact

occurring just north of the range boundaries The Soviet range

areas lend themselves well to middotthe maintenance of tight security

The southern boundaries of the available rarge area would

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

etry design calls for folded wing$ on the leeward side of a

relatively compact vehicle Aiter the vehicle has slowed down and

reached a low altitude the wings are unfolded to provide control

In the design opound a vehicle which re middotenters the atrnogphere

from the moon it is assumed that the objective of re-entry is to

arrive at a particular point on the earth1 s surface If it has no

guidance system the vehicle will depend entirely on the forces that

act upon it during its precalculated trajectory Thue it may be

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

trajectory Assuming that the prelaunch calculations can be

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

etry design calls for folded wing$ on the leeward side of a

relatively compact vehicle Aiter the vehicle has slowed down and

reached a low altitude the wings are unfolded to provide control

In the design opound a vehicle which re middotenters the atrnogphere

from the moon it is assumed that the objective of re-entry is to

arrive at a particular point on the earth1 s surface If it has no

guidance system the vehicle will depend entirely on the forces that

act upon it during its precalculated trajectory Thue it may be

best that the vehicle has no lift since unexpected variations in

Problems which affect the earth entry of a returning lunar

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

U) LUNAR RE-ENTRY VEHICLE

In order to determine what site selection criteria should be

used in selecting an optimum lunar recovery range the design

characteristics of the proposed re-entry vehicle must be defined U

US design studies related to the development of a lunar

1middoteturn re-entry vehicle have pomted out the complexity in the

overall systems design for this type of mission Ultimate vehicle

design will be largely dependent on the supercrbital velocities

enccunte1middoted upon re-entry into ~e earths atmosphere Velocities

encountered will be near 36000 fps as opposed to the nominal

25000 poundps encoUntered by a low earth orbit vehicle The

inaccuracy in tracking vehicles at auperorbital velocities over long

distances also becomes a sfgtrious problem during the return leg of

the lunar trajecto-y as well cs iurirg enrv into --gt -bull rtigt

atmosph middota (TT)

All space vehicles entering the earths atmosphere at ltgtupershy

orbital velocities can be classed into two broad groupe --those

with no lift (ie ballistic) and these whose lift-to-drag ratio

(L ) ) 0 Re-entry vehicles in the latter group also fall into0

two classes -- those of a fixed design with a constant lift

Pnor to asses Bing the op~ratioral characteristics of a land

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

elements involved and velocity requil-ed to achieve the proper

trajectory Assuming that the prelaunch calculations can be

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

Pnor to asses Bing the op~ratioral characteristics of a land

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

The use of a semi-ballistic lunar re-entry vehicle (nominal

A review of current Soviet earth orbit recoveries indicates

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

analysis is necessary throughout the entire flight By using

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

The lifting vehicles LID ) 1 although ofiering a wider

re-entry corridor and more maneuverability necessitates a more

complex design criteria and mission control system (U)

Pnor to asses Bing the op~ratioral characteristics of a land

vehicles it is necessary to define the external parameters which

influence site selection (81

Problems which affect the earth entry of a returning lunar

vehicle are inherent_ in the entire system beginning with the powered

flight phase of the trajectory Accurate preprogrammed trajectory

calculations which best fit the mission are initially controlled by

geometrical constrainta such as the location of the launch and

recovery sites azimuth of fire declination o( the moon time

analysis is necessary throughout the entire flight By using

inertial or ground radio command guidance syJtems the vehicle

can then be corrected along its trajectory making it possible to

hit a precalculated earth re-entry window Thi~lt window constrains

the allowable tolerances of the re-entry vehicle and governs the

As discussed in Section I a pure ballistic re-entry vehicle

design for lunar return missions necessitates the use of a narrow

re-entry corridor with low tolerances on guidance accuracy The

use of such a system would require an extremely accurate ground

based tracking network providing finite data during the terminal

leg of flight (U)

re-entry corridor and more maneuverability necessitates a more

For a relatively high lift (LID ) I) lunar re-entry

vehicle the equipment requirements increase substantially for

both orbital corridor stations and the recovery site Continuous

tracking will be required from the deboost point to the impact

site which wi ll normally result in an initial need for at least

eight tracking stations along the orbital corridor This arrangeshy

ment will provide continuous tracking from deboost to landing

ln the recovery area the probable instrumentation requirements

include C and S band radaramp radio D F equipment airborne

radars precision doppler radars for velocity measurement)

mobile ground radars (for immediate off -range coverage) angle

and distance measuring equipment tracking telescopes and

ballistic cameras Absolute minimum instrumentation requireshy

proposed boundaries of tte lunar recovery range and could continue

to be used dependent on the external constraints o the chosen

lunar mission and its re-entry vehicle characteri11tics It should

be remembered however that these are limiting site selection

factors and the area proposed is made with no knowledge of USSR

lunar recovery mission technology m The broad boundaries of the proposed recovery range include
