CHALLENGERStage V

CHALLENGER (Stage 5) requirements:

1. The Written PhaseThe cadet must successfully pass a review questions on basic elements of high power rocketry before going to the hands-on phase.

2. The Official Witness Log (OWL) And for review questionsThe cadet must have the unit Aerospace Education Officer (AEO) administer the review questionsor verify from LMS sign the OWL after the cadet achieves a successful score.

3. The Hands-On PhaseThe cadet is required to build a high power rocket. The rocket built in the Columbia (Stage IV) maybe suitable for flight as a high power rocket. If so, the same rocket may be used for the Challenger(Stage V) (reference the supplemental information contained in Stage IV as well as possible modifi-cations outlined in Stage V).

4. The Official Witness Log (OWL) For Construction (Optional) And Flight (Required) Of A High Power RocketThe culmination of CAP’s advanced rocketry program will result in the cadet receiving a JuniorHigh Power Rocketry Certification (ages 14 through 17) or a standard (adult) High Power RocketryCertification (ages 18 and up). Certification is conducted by qualified members of the National As-sociation of Rocketry (NAR), some of who may be members of CAP. The cadet is required to suc-cessfully fly and recover the rocket on a high power (“H” or “I”) motor. The QSM reviews the NARdocumentation certifying the successful flight and then signs the OWL.

5. The Role Of The Squadron CommanderAfter Completion of the above requirements, the cadet is entitled to receive the Challenger certifi-cate. The squadron commander must review the completed OWL and sign the certificate. Sincethis represents a major accomplishment in the CAP rocketry program, it is recommended that thecertificate be presented at a squadron awards ceremony.

ModUle introdUctionChallenger (Stage V) represents the culmination not just of CAP’s advanced rocketry program offered to cadets. Uponsuccessful completion, cadets will be qualified and authorized to fly high power rockets (HPR) in the H and I impulse clas-sifications (up to 640 Newton-seconds total impulse). Cadets between the ages of 14 and 18 will be permitted to fly underqualified adult supervision. Those over age 18 will be permitted to fly HPR on their own, as well as mentor and certifyyounger cadets.

HPR is an exciting new addition to the basic CAP model rocketry program. For those cadets wishing to pursue it, HPR af-fords an opportunity to fly rockets much larger, higher, and faster than anything conventional model rocketry has to offer.For those cadets planning to pursue STEM-related curricula in college, they may find that their programs of study will in-clude High Power Rocketry as part of the coursework (a prime example being the United States Air Force Academy).Cadets who have mastered these skills in CAP will be that much farther ahead of their peers when it comes time to workon advanced rocketry projects in college.

Moving into HPR requires some very specific knowledge and skill mastery in order to be successful. In the Columbiastage cadets were introduced to some very important advanced construction techniques which are used throughout HPR.The Challenger stage will provide an introduction to the rules and regulations that govern HPR, as well as the advancedpropulsion systems which are utilized.

overvieW oF HiGH PoWer rocKetryHigh power rocketry is defined and/or regulated by three distinct entities: the national rocketry organizations; specifically,National Association of Rocketry (NAR) and Tripoli Rocketry Association (TRA), the National Fire Protection Association(NFPA), and the Federal Aviation Administration (FAA). NAR and TRA are involved with establishing certification proce-dures, safety codes, and motor classifications. HFPA has established instructional guidelines and specific standards forthe design, construction, reliability, and power limitations of the manufacturing of motors, as well as other aspects of HPRso as to minimize hazards associated with the activity. The FAA, as one can imagine, is concerned with the potential haz-ard presented to aircraft, and regulates HPR under Federal Aviation Regulation (FAR) Part 101, Subpart C.

In the early 1980s, interest began growing in flying rockets of significantly higher power than what was typical for modelrockets (the upper limit commonly being the D motor, although there were some manufacturers producing E and F mo-tors). The introduction of composite propellant is basically what allowed for the development of HPR.

Initially, NAR wanted to focus on model rocketry and not involve itself in HPR. With a need for a national organization togovern HPR, the Tripoli Rocketry Association was formed. In the years following the establishment of TRA, NAR realizedthe value of HPR and subsequently adopted its own program. Today, TRA is exclusively an HPR organization, while NARis involved in model rocketry as well as HPR. The two organizations have a very cordial relationship where, under mostcircumstances, a member of TRA can fly at a NAR event and vice versa. TRA does have a “research” category whichNAR does not have; consequently, NAR members would have some limitations imposed at TRA launches that are classi-fied as “research”.

Additionally, TRA does not have a Junior HPR certification category, as NAR does. Therefore, CAP cadets wishing to pur-sue Stage V will be required to join NAR in order to complete the program. The current cost for a cadet’s one-year mem-bership in NAR is $25.

Motor iMPUlSe claSSiFicationSBy now, cadets who have progressed this far in the rocketry program are familiar the motor classifications that were es-tablished by NAR in the early days of model rocketry. HPR uses that same basic formula to classify motors; it just goesmuch farther down into the alphabet! The following chart will show model-rocket-classified motors on the left side (alsoclassified as low and mid power motors), and HPR motors shown on the right side. To review: Ns means Newton-sec-ond, which represents one Newton of force for one second.

The chart stops at “O” because that is currentlythe largest commercially manufactured HPRmotor. The term “low power” generally appliesto motors rated D and below, and “mid power”applies to motors rated E through G.

reloadaBle MotorSThe purpose of using reloadable rocket motors in high power rocketry is based solely on economics. While the up-frontcosts are higher (due to the initial acquisition of reusable motor hardware), after only a few uses, reloadable motors be-come more economical than motors that are used once and then thrown away. For this reason, high impulse rocket mo-tors are almost exclusively offered as reloadable—there are very few high-impulse single use motors available.

Of the reloadable motors that are avail-able commercially, some are almost com-pletely reusable (including the nozzle),while others are mostly reusable (wherethe nozzle is replaced after each flight).There are also some types where all ofthe reloadable parts are assembled at thefactory, and others where none of theparts are assembled and that job is left tothe user (again the issue is economics).It follows then, that a design that requiresusers to essentially assemble the motorfrom a bag of parts would be less expen-sive than the same type of motor that wasoffered by a manufacturer who had to paya worker to perform the assembly in afactory.

A visual comparison of two of the mostcommon types of reload “kits” is shown tothe right:

Aerotech brand reloads require assembly

24

The aluminum casing that houses the propellantand motor components is reusable and has vir-tually an indefinite life. Reusability is the key tothe economy of using reloadable motors oversingle-use. To illustrate, a squadron could pur-chase a casing for all cadets to use. Theshared use of the hardware would greatly re-duce the cost of each individual flight.

Cesaroni Pro29 and Pro38 brand reloads come completely assembled—components shown to the left are installed in the black liner at the factory.

HiGH PoWer rocKetry certiFicationA through G motors are available at many hobby stores and may be purchased without any certification. The purchase ofH motors and above does require a certification affidavit (cert card) that indicates the individual is qualified to fly (andtherefore purchase) such motors. Certification is broken down into three levels:

Level 1: H and I motorsLevel 2: J through L motorsLevel 3: M motors and above

The NAR Jr. HPR certification is a modification of Level 1. CAP cadets who certify under this category, will be permitted tofly H and I motors under qualified adult supervision. A qualified adult supervisor is defined as a NAR adult member withHPR certification of Level 1 or above. The adult member of NAR does not need to be a member of CAP; however, anyAEO (or any adult member of CAP for that matter) may join NAR and become HPR certified—in doing so, he or she wouldprovide an in-house resource that would be a valuable asset to any cadet advanced rocketry program.

High power certified fliers are limited to the total impulse they may fly on a single flight. For example, a Level 1 flier couldnot fly a motor cluster, or fly a multi-stage rocket, using two I motors because that would put the total installed impulse intothe J impulse classification. Consequently, a J impulse flight would require a Level 2 certification.

Certification for Jr. Level 1 is simple and straightforward. The candidate must first build a rocket capable of accomplishinga successful flight powered by an H or I motor. He or she must then demonstrate a successful flight using an H or I motorin the presence of a designated individual or certification team. In order for the certification to be valid, the candidate mustbe a member of NAR. Membership may be activated at the time of the certification flight. In other words, the NAR mem-bership application may be submitted at the same time the HPR certification flight is accomplished.

CAP cadets 18 and over may choose to go beyond HPR Level 1. Advancement to the higher levels requires a thoroughunderstanding of, and experience in, high power rocketry. For example, certification for Level 2 is somewhat more com-plex than Level 1. The candidate must build a rocket capable of accomplishing a successful flight powered by a J, K or Lmotor. It is permissible to use the same rocket for the Level 2 flight as was used for the Level 1 flight (assuming therocket can withstand the stresses of a significantly more powerful motor). The candidate must also pass a written examconsisting of 50 multiple-choice questions relating to the technical and safety aspects of high power rocketry. Once thetest is passed and a successful flight is accomplished on a J, K, or L motor, the individual is certified at Level 2. The sametype of witness and membership requirements for Level 1 also apply for Level 2.

Certification for Level 3 requires the candidate to submit a project proposal to a NAR member specifically designated toapprove such projects. The rocket design must meet specific minimum objectives in the areas of construction, stability,recovery, and electronics. Once the design is approved and construction is completed, the flight must be powered by a

25

commercially manufactured and certified motor, the minimum impulse of which, exceeds 5,120 Ns, but is not greater than40,960 (M through O motors). Authority to witness and act as a certifying official is limited to a specific group of individu-als so designated by NAR.

Certification levels must be accomplished in sequence and no levels may be skipped. Once cadets turn 18, they may cer-tify either through NAR or TRA. It is only the Jr. HPR certification that must go through NAR (since NAR is the only one ofthe two organizations that offers that certification category).

USe oF on-Board electronicSOn-board electronics can be used extensively in high power rocketry—or not at all. The only “electrical” requirement isthat the motor be ignited by electrical means, which is accomplished with a ground controller that is not part of the rocket.A high power rocket can operate in flight much like a simple Estes-type model rocket, wherein the motor propellant burnsthrough thrust termination, a “delay” element burns which produces no thrust and allows the rocket to coast to apogee,and then a small black powder ejection charge (activated by the burn-through of the delay charge) fires to deploy the re-covery system—all of which required no on-board electronics. The following paragraphs will, however, discuss some ofthe many electronic devices available for use in HPR.

Barometric altimeter

Consider the following scenario:

An on-board electronic device could allow the recovery system deployment of a rocket to happen in stages, ratherthan a single event. At apogee, a small drogue parachute could be released in order to disturb the aerodynamiccharacteristics of the rocket. This would allow the rocket to descend rapidly but prevent it from turning into anaerodynamic projectile. Once the rocket descended to a few hundred feet above the ground, the device couldthen release the main parachute and allow the rocket to gently land.

The described device is now in widespread use in high power rocketry in many forms and variations, and offered by manymanufacturers (and represents perhaps the most common usage of electronic devices in high power rocketry). An addedbonus to flying this type of device is that it will report the altitude recorded at apogee.

timer

Another useful device is an event timer. The device utilizes an accelerometer which will detect motor ignition as well asburnout. The timer normally has the capability to trigger at the moment it detects a particular event, or to enter a timedelay mode before it triggers. Zero delay would be useful in igniting a secondary cluster of motors on the ground. Timedelays are useful in initiating a staging sequence, jettisoning a set of strap-on motors, or air starting a secondary clusteron a single stage rocket.

Flight computer

Flight computers are very powerful devices which can be programmed to perform a variety of functions. One such com-puter has the capability to detect five different events and react instantly or after a preprogrammed elapsed time. A flightevents recorder will provide a readout either real-time (for telemetering to the ground) or stored for later down-load of pa-rameters such as acceleration, ascent velocity, altitude (both barometric and accelerometer), and descent rate. Interfacewith a PC will create line graphs of the events vs. time. Many flight computers have the capability of storing recorded datafrom multiple flights, thus reducing the need to carry a computer to the flying field.

telemetry

As mentioned above, the capability exists to telemeter the on-board data real-time to a ground receiver. The telemetrystream could also include a real-time video image from an on-board camera.

26

locating devices

Depending on the flying field, the rocket may land in an area obstructed with trees or tall grass which can hamper recov-ery. The terrain may contain dips or ravines which could also disrupt the direct line-of-sight of a landed rocket. There aredevices available which can aid the recovery process which range from the very simple and inexpensive, to quite sophisti-cated (and expensive).

The simplest and least expensive is the audible locator. The device activates during a recovery event (either drogue ormain deployment) and emits a high decibel sound which serves to give away its location. The down-side to this device isthat once on the ground, the audio radius is greatly reduced. It is certainly better than nothing and its effectiveness hasbeen proven on numerous occasions.

An intermediate level of sophistication (and cost) is a radio beacon. A transmitter rides on board the rocket and emits apulsed signal. The signal is picked up by a directional receiver and the variations in intensity of the signal will lead the re-ceiver in the direction of the transmitter.

The most sophisticated (and expensive) is GPS. However, the receiver will give the locating team a graphic map (to in-clude lat/long) of precisely where the rocket is located. What could be easier?

imagery

Still and full motion video imagery is easily obtainable with tiny on-board mounted cameras. The imagery can be recordedinternally for later download, or, as stated earlier, it can be telemetered to the ground real-time during flight.

Faa reQUireMentSIt doesn’t take a rocket scientist to figure out that a high power rocket zooming up to several thousand feet at several hun-dred miles an hour would pose a hazard and even a danger to aircraft. Hence, the FAA is very concerned about HPR ac-tivities. So much so that there is an entire regulation devoted to the subject: FAR 101, Subpart C (as mentionedpreviously). Local chapters of the national organizations (known as “sections” for NAR, and “prefectures” for TRA) willhave accomplished all the prerequisites and coordination required to conduct an HPR event by the time the rocket fliersshow up on launch day. That is one of the many advantages of flying with a local club—all the regulatory issues havebeen taken care of for you!

The FAA has a very concise description of what it considers a model rocket and what it considers an HPR. That descrip-tion (taken directly from FAR Part 101, Subpart C) is reprinted here in its entirety:

101.22 definitions.

The following definitions apply to this subpart:(a) Class 1—Model Rocket means an amateur rocket that:(1) Uses no more than 125 grams (4.4 ounces) of propellant;(2) Uses a slow-burning propellant;(3) Is made of paper, wood, or breakable plastic;(4) Contains no substantial metal parts; and(5) Weighs no more than 1,500 grams (53 ounces), including the propellant.

(b) Class 2—High-Power Rocket means an amateur rocket other than a model rocket that is propelled by a motoror motors having a combined total impulse of 40,960 Newton-seconds (9,208 pound-seconds) or less.

(c) Class 3—Advanced High-Power Rocket means an amateur rocket other than a model rocket or high-powerrocket.

BUildinG a HiGH PoWer rocKetThe building techniques outlined in Stage IV are to be utilized as well in Stage V. Stage IV described an option by whichthe same rocket built for Stage IV could also be used for Stage V. If that option was exercised, then no further construc-tion is necessary (although some modification may be required). If the Stage IV rocket is not configured for HPR flight(and can not be modified), then the cadet will need to construct another rocket. It may be in kit form or may be of his orher own design. There are numerous kit manufacturers as well as vendors that sell individual rocket parts. There arealso several design software programs available (some for purchase, some for free). A resource list will be provided atthe end of the chapter.

An example of a rocket kit that is suitable for both Stages IV and V. Shown are the piece parts of the LOC/Precision “Graduator”

The assembled Graduator rocket stands 40 in. tall and can fly on E through H motors—a very versatile rocket.

Due to the much higher altitudes and higher speeds capable of HPRs, a method of venting internal pressure must be in-cluded in the rocket design. As a rocket rises rapidly, external air pressure will become lower due to the rise in altitude.Air trapped inside the body tube will therefore become greater than the outside pressure, and the possibility of the nosecone popping off becomes real. With the nose cone deployed, the rocket will become unstable, the parachute could comeout, and a complete vehicle break-up could occur all while the rocket is still under power. A small vent hole (approx. 1/8in. diameter) positioned anywhere near the rear of the nose cone’s internal position in the body tube, and forward of thetop motor mount centering ring should prevent a failure due to internal pressure build-up. The method described shouldbe suitable for most rockets constructed in Stage V. Note however, that rockets with larger internal volumes will requiremultiple and/or larger vent holes. An Internet search using the terms “rocket vent hole formula” will return helpful informa-tion. Any rocket built in Stage IV that is planned to be flown for Stage V should be modified as described above (if not al-ready accomplished).

Effective motor retention is also important for HPR flights. While a good snug friction fit is feasible, it is strongly recom-mended that a more positive method of motor retention be employed for a Stage V rocket. The arrangement illustrated in

28

the Stage IV text is one such method. Others are available. An Internet search using the terms “hpr motor retention” willreturn helpful information.

Due to the higher altitudes attainable on HPR flights, the possibility of loosing the rocket increases. Size and terrain of theflying field will also be a factor in successfully locating a rocket after it’s landed. If there is any concern regarding the pos-sibility of loosing sight of the rocket, then some method of electronic locating assistance should be considered. The small,inexpensive, audible locating devices mentioned in the “Onboard Electronics Section” would be an excellent way of help-ing assure rocket recovery. Additionally, the size of the parachute may be lessened, either by cutting a spill hole in the topor by constraining the shroud lines. Using interchangeable parachutes could also be utilized—a larger one for lower alti-tude flights and a smaller one for higher altitude flights. Keep in mind that a smaller parachute will increase the decentrate and increase the chance of landing damage. A broken fin, for example would disqualify a candidate on a certificationflight.

FlyinG a HiGH PoWer rocKet and laUncH SaFety conSiderationSPreparation for flight will follow the same basic procedure used for Stage IV. Note that different rocket designs will requiredifferent preparation procedures. For example, a “piston” parachute deployment system does not require the use of pro-tective wadding, so the preflight preparation for that type of rocket would differ somewhat from a more conventional de-sign. Rockets built from kits will have “preflight instructions” included with them. Rocket motor manufacturers will includeinstructions for motor assembly, preflight preparations, and post flight handling.

The easiest way to accomplish the flight is to seek out a local NAR section. NAR has a section directory on its website.The local NAR section should also be able to provide a qualified team or individual who can perform the Jr. HPR certifica-tion. If a section is not established in the local area, also consider TRA. Tripoli prefectures will often have NAR memberswho are qualified to conduct certifications. If neither of these options is viable, contact CAP National Headquarters forguidance.

Rocket motors are often available for purchase from venders that will be set up on the flying field on the day of the launch.If the local rocket club does not have on-site vender support, motors may also be purchased through mail order.

The important elements of launch safety are covered in the high power rocketry safety codes of TRA and NAR. The on-line NAR code is included here in its entirety.

Effective August 2012

1. certification. I will only fly high power rockets or possess high power rocket motors that are within the scope of myuser certification and required licensing.

2. Materials. I will use only lightweight materials such as paper, wood, rubber, plastic, fiberglass, or when necessary duc-tile metal, for the construction of my rocket.

3. Motors. I will use only certified, commercially made rocket motors, and will not tamper with these motors or use themfor any purposes except those recommended by the manufacturer. I will not allow smoking, open flames, nor heatsources within 25 feet of these motors.

4. ignition System. I will launch my rockets with an electrical launch system, and with electrical motor igniters that are in-stalled in the motor only after my rocket is at the launch pad or in a designated prepping area. My launch system willhave a safety interlock that is in series with the launch switch that is not installed until my rocket is ready for launch, andwill use a launch switch that returns to the “off” position when released. The function of onboard energetics and firingcircuits will be inhibited except when my rocket is in the launching position.

5. Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove thelauncher’s safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allow-ing anyone to approach the rocket.

6. launch Safety. I will use a 5-second countdown before launch. I will ensure that a means is available to warn partici-pants and spectators in the event of a problem. I will ensure that no person is closer to the launch pad than allowed bythe accompanying Minimum Distance Table. When arming onboard energetics and firing circuits I will ensure that noperson is at the pad except safety personnel and those required for arming and disarming operations. I will check thestability of my rocket before flight and will not fly it if it cannot be determined to be stable. When conducting a simulta-neous launch of more than one high power rocket I will observe the additional requirements of NFPA 1127.

7. launcher. I will launch my rocket from a stable device that provides rigid guidance until the rocket has attained aspeed that ensures a stable flight, and that is pointed to within 20 degrees of vertical. If the wind speed exceeds 5miles per hour I will use a launcher length that permits the rocket to attain a safe velocity before separation from thelauncher. I will use a blast deflector to prevent the motor’s exhaust from hitting the ground. I will ensure that dry grassis cleared around each launch pad in accordance with the accompanying Minimum Distance table, and will increasethis distance by a factor of 1.5 and clear that area of all combustible material if the rocket motor being launched uses ti-tanium sponge in the propellant.

8. Size. My rocket will not contain any combination of motors that total more than 40,960 N-sec (9208 pound-seconds) oftotal impulse. My rocket will not weigh more at liftoff than one-third of the certified average thrust of the high powerrocket motor(s) intended to be ignited at launch.

9. Flight Safety. I will not launch my rocket at targets, into clouds, near airplanes, nor on trajectories that take it directlyover the heads of spectators or beyond the boundaries of the launch site, and will not put any flammable or explosivepayload in my rocket. I will not launch my rockets if wind speeds exceed 20 miles per hour. I will comply with FederalAviation Administration airspace regulations when flying, and will ensure that my rocket will not exceed any applicablealtitude limit in effect at that launch site.

10. launch Site. I will launch my rocket outdoors, in an open area where trees, power lines, occupied buildings, and per-sons not involved in the launch do not present a hazard, and that is at least as large on its smallest dimension as one-half of the maximum altitude to which rockets are allowed to be flown at that site or 1500 feet, whichever is greater, or1000 feet for rockets with a combined total impulse of less than 160 N-sec, a total liftoff weight of less than 1500grams, and a maximum expected altitude of less than 610 meters (2000 feet).

11. launcher location. My launcher will be 1500 feet from any occupied building or from any public highway on whichtraffic flow exceeds 10 vehicles per hour, not including traffic flow related to the launch. It will also be no closer thanthe appropriate Minimum Personnel Distance from the accompanying table from any boundary of the launch site.

12. recovery System. I will use a recovery system such as a parachute in my rocket so that all parts of my rocket returnsafely and undamaged and can be flown again, and I will use only flame-resistant or fireproof recovery systemwadding in my rocket.

13. recovery Safety. I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places, fly itunder conditions where it is likely to recover in spectator areas or outside the launch site, nor attempt to catch it as itapproaches the ground.

SUMMaryHigh Power Rocketry is an exciting new component to the cadet program. Cadets age 14 and over may explore newareas of advanced rocketry concepts that go far beyond the basic model rocketry program. The advanced rocketry pro-gram has a very practical application to those cadets wishing to pursue STEM programs of study in college.

CAP units that become active in advanced rocketry and are fortunate enough to be located near an active HPR club willfind that rocketry launches may become a much anticipated monthly activity. Monthly club launches often attract dozens(sometimes upwards of a hundred or more) participants flying a wide variety of rocket designs. In addition to cadets flyingtheir own rockets, they will be able to see many advanced rocket designs, some of which resemble actual full size NASAsounding rockets! Additionally, active rocket clubs typically have numerous experienced and seasoned rocket fliers, manyof whom would be more than happy to help cadets (and adults) get started in this dynamic activity.

Example of an advanced 2-stage HPR designed to fly on combinations of J, K, L, M, or N class motors (with booster requiring at least an L motor for stable flight).
