ABOUT HAL

HAL came into existence on 1st October 1964.

The Company was formed by the merger of

Hindustan Air craft Limited with Aeronautics India

Limited and Air craft Manufactur ing Depot, Kanpur.

The Company traces its roots to the pioneering

efforts of an industrialist with extraordinary vision, the

late Seth Walchand Hirachand, who set upHindustan Aircraft Limited at Bangalore in association

with the erstwhile princely State of Mysore in

December 1940. The Government of India became a

shareholder in March 1941 and took over the

Management in 1942.



MISSION

To become a globally competitive

aerospace industry while working as an

instrument for achieving self ±reliance in

design, manufacture and maintenance of Aerospace defense equipment and

diversifying to related area , managing

the business on commercial lines in a

climate of growing professionalcompetence .

Specif ication of Sukhoi SU-30 MKI

Crew: 2

L ength: 21.935 m

Wingspan : 14.7 m

Height: 6.36 m

Wing area: 62.0 m²

Empty weight: 17,700 kg

Loaded weight: 24,900 kg

Max takeoff weight: 38,800 kg

Maximum speed: Mach 2.35(2,500 km/h) at 11,000m. Range: 5,000 km (2,700 nmi) with internal fuel tank.



Fuel Tanks:

Number of fuel tanks: 6

Name of fuel tanks: 1, 2, 3RT,3LT, 4, 5

Fuel Capacity: 1

200 kg

Special detail: Tank no. 2 is themain tank & also known asservice tank having fuel capacityof 600 kg



Fuel Systems:

Purpose of an aircraft fuel system is:

To store & deliver the proper amount of clean fuel at thecorrect pressure to the engine

Fuel systems should provide positive and reliable fuel flowthrough all phases of flight such as1)Changes in altitude 2)Violent maneuvers3)Sudden acceleration and deceleration

Fuel systems should also continuously monitor systemoperation such as: Fuel pressure Fuel flow Warning signalsTank quantity



Types of Fuel Systems:

Types of Fuel Systems can be classified in two broad categories:

Gravity-Feed Systems: Gravity-Feed Systems use onlythe force of gravity to push fuel to the engine fuel-controlmechanism .

Reason for this system to exist in an aircraft:

1)The bottom of the fuel tank must be high enough to

provide adequate pressure to the fuel-control

component.

2)This type of system is often used in light aircraft.



Pressure-Feed Systems: Pressure-Feed Systems require theuse of a fuel pump to provide fuel-pressure to the engine·sfuel-control component.

Reason for this system to exist in an aircraft:

1)The fuel tanks are too low to provide enough pressurefrom gravity.

2)The fuel tanks are at great distance from the engine.

3) Also, most large aircraft with higher powered engines

require a pressure system regardless of the fuel tanklocation because of the large volume of fuel used by the

engines.



Fuel flow & meter ing system:

This system measures fuel quantity available in aircraft. This

system performs following major function:

1) Fuel f low metering: - This part computes total quantity of fuel available in aircraft & transmits to various airborne

system for display & recording.

2) Fuel q uantity gauging :- This part exclusively computes

quantity of fuel available in service tank & transmit to variousairborne system for display & warning.

3) Automatic control :- This part manages sequence of fuel

flow to/from various tanks during refueling as well as during

consumption.







Fuel Quantity Unit: BT3-4This instrument computes quantity of fuel in service tank

based on signals from sensors which are fuel probes (DT41).

It delivers computed information to following instruments:

1) Digital light indicator(ITSS7-1)

2) Refueling Control Panel(PKUZ&-2)

3) Stand by Equipment(SBI)

4) Complex Information Signaling System(KISS)

It gives warning signal to pilot for residual fuel of 150 kg in

main tank.



Fueling Control Panel:

PKUZ7-2

This instrument is a display device & is used on

ground during refueling. It performs followingfunctions:

1) To display total fuel quantity

2)To display fuel quantity of service tank

3)To display actual fuel density



Electronic transducer

unit:BE

P51-1

This unit is main processing part of automatic control portion

of STR7-51 system. It manages fuel flow based on signals fromsensors, magnetic operated level switches (DSMKs) fitted in

various tanks. It also senses total residual fuel quantity &

transmits the warning signal to pilot.





Cockpit:

It has multi-function display.

Made up of special LCD.

This LCDs can withstand a

temperature of -40 degreeCelsius.

It can absorb repeated violentimpacts of landing on aircraft

carriers. The display is easily readable

even in bright sunlight & dimenough for the pilot to read atnight without losing night vision.



Engines:

Su-30MKI is powered by the Al-31FP (F for forsazh & P forpovorotnoye means afterburningmovable) turbofan engines.

The Al-37FU engine have 2D ThrustVectoring Control (TVC) Nozzles.

2D TVC means that the Nozzles canbe directed/pointed in 2 axis or

directions - up or down.

TVC makes an aircraft much moremaneuverable.



Turbofan engine





Continued«..

The nozzles of the MKI are capable of deflecting 32 degrees

in the horizontal plane and 15 degrees in the vertical plane.
