HAL, ACCESSORIES DIVISION, LUCKNOW

HAL came into existence on 1st October 1964.The Company was formed by the merger of Hindustan Aircraft Limited with Aeronautics India Limited and Aircraft Manufacturing Depot, Kanpur. The Company traces its roots to the pioneering efforts of an industrialist with extraordinary vision, the late Seth Walchand Hirachand, who set up Hindustan Aircraft Limited at Bangalore in association with the erstwhile princely State of Mysore in December1940.

ABOUT HAL

The Government of India became a share holder in March 1941 and took over the Management in 1942.

During the 1980s, HAL's operations saw a rapid increase which resulted in the development of new indigenous aircraft such as HAL Tejas and HAL Dhruv. HAL also developed an advanced version of the MiG-21, known as MiG-21 Bison, which increased its life-span by more than 20 years.

HAL has also obtained several multi-million dollar contracts from leading international aerospace firms such as Airbus, Boeing and Honeywell to manufacture aircraft spare parts and engiene.

19 Production Units and 9 R&D in 7 locations over India

FUEL SYSTEMS

Purpose of an aircraft fuel system is:1. To store & deliver the proper amount of clean fuel at

the correct pressure to the engine

2. Fuel systems should provide positive and reliable fuel flow through all phases of flight such as

o Changes in altitudeo Violent maneuvers

o Sudden acceleration and deceleration

3. Fuel systems should also continuously monitor system operation such as: Fuel pressure ,

fuel flow warning signals , tank quantity.

FUEL TANKS

Number of fuel tanks: 6

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

• Fuel Capacity: 1200 kg• Special detail: Tank no. 2 is the main

tank and also known as service tank having fuel capacity of 600 kg.

FUEL FLOW & METERING SYSTEM: STR7-51

Fuel flow metering: - This part computes total quantity of fuel available in aircraft & transmits to various airborne systems for display & recording.

Fuel quantity gauging : - This part exclusively computes quantity of fuel available in service tank & transmits to various airborne systems for display & warning. Automatic control: - This part manages sequence of fuel flow to/from various tanks during refueling as well as during consumption.

This system measures fuel quantity available in aircraft. This system performs following major function:

FUEL QUANTITY TRANSMITTERS: DT41

These sensors are used for computing fuel quantity in service tank. Capacitance of the probes changes based on the variation in fuel level in tank. Resultant capacitance of following probes acts as an input for computing fuel in service tank. Different capacitance probes used in Su-30MKI are DT41-4, DT41-5, DT41-6, DT41-7, and DT41-8.

FUEL FLOW TRANSMITTERS: DRT2-2A

These are impeller types of sensors which produces signal proportional to the rate of flow of fuel through it.

Fuel consumed by aircraft is computed based on the signals provided by these sensors.

FUEL QUANTITY UNIT: BT3-4

Digital light indicator(ITSS7-1)Refueling Control Panel(PKUZ&-2)Stand by Equipment(SBI)Complex Information Signaling System(KISS)

This 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:

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

FUELING CONTROL PANEL: PKUZ7-2

To display total fuel quantity

To display fuel quantity of service tank

To display actual fuel density

This instrument is a display device & is used on ground during refueling. It performs following functions:

ELECTRONIC TRANSDUCER UNIT:BEP51-1

This unit is main processing part of automatic control portion of STR7-51 system.

It manages fuel flow based on signals from sensors, magnetic operated level switches (DSMKs) fitted in various tanks.

It also senses total residual fuel quantity & transmits the warning signal to pilot.

SEMICONDUCTOR RELAY CONTROL UNIT: BUPR21-1

This is a part of automatic control portion of STR7-51 system.

This instrument works as an amplifier & a switching device for the signals required for opening & closing of valve of various tanks of aircraft.

COCKPIT

It has multi-function display. 

Made up of special LCD. 

These LCDs can withstand a temperature of -40 degree Celsius. 

• It can absorb repeated violent impacts of landing on aircraft carriers.

• The display is easily readable even in bright sunlight & dims enough for the pilot to read at night without losing night vision.
