COLLABORATIONS WITH COMPANIES
Accessories Division of HAL was established in 1970 with the primary objective of manufacturing system and accessories for various aircraft and engines and attain self sufficiency in this area.
Its facilities are spread over 1,16,191 square m. At present it is turning out over 1132 different types of accessories.

SUKHOI-30 MKI
SUKHOI Su-30 MKIThe Sukhoi Su-30MKI has been jointly-developed by Russia's Sukhoi Corporation and India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). It is a heavy class, long-range air superiority fighter aircraft. The Su-30 MKI is more advanced than the basic Su-30MK, the Chinese Su-30 MKK, and the Malaysian Su-30 MKM. The aircraft features state of the art avionics developed by Russia, India , Israel , France and South Africa which includes display, navigation, targeting and electronic warfare systems.
MKI stands for "Modernizirovannyi Kommercheskiy Indiski" meaning "Modernized Commercial India".
GENERAL FEATURES OF Sukhoi 30 MKI Sukhoi 30 MKI is a 4.5 generation fighter aircraft . Fifth generation planes are yet to come. Cost of single Su-30 MKI is $ 35 million or Rs 1.61 billion As per deal between Russia’s Sukhoi Corporation and India’s HAL , in the first phase, components will be imported from Russia and only assembling will be done in India. In the second phase , there will be transfer of technology from Russia to India , and then both manufacturing & assembling will be done in India. Various independent sources have claimed Su-30 MKI to be the most superior fighter plane in present World.
FUEL FLOW AND METERING SYSTEMIn Sukhoi 30 MKI
Fuel capacity of Sukhoi 30 MKI: 12 ton or 12000Kg There are 5 fuel tanks of which one is service tank or main tank. Service tank is centrally located is the most important one. Fuel from all other tanks pass through service tank before consumption. So in the end fuel remains only in the service tank. All the 5 tanks are so placed that the aircraft is aerodynamically balanced.

STRUCTUREFuel quantity & flow metering system can be subdivided into:1. Fuel Flow Metering > It computes the total quantity of fuel available in aircraft. Uses impeller type of sensors.
2. Fuel Quantity Gauging > It computes the quantity of fuel in the service tank. Uses capacitance type electronic sensors.
3. Automatic Control > It manages the sequence of fuel flow to/from various tanks during refueling and consumption.
FUEL FLOW METERING Computes the quantity of fuel left in aircraft.
Based on the principle of impeller movement.
Impeller is a device which rotates due to the movement of liquid(fuel) through pipe. One complete rotation of impeller is associated with a unique amount of fuel flow. This gives us the volume of fuel consumed. So weight of fuel consumed: weight of fuel = volume * density
Net fuel remaining = initial quantity of fuel – fuel consumed
FUEL QUANTITY GAUGING Computes the quantity of fuel left in service tank. It is an electronic system based on the principle of variation of capacitance with change in dielectric medium. It consists of uniform cylindrical shaped capacitor with the fuel acting as the dielectric. As the fuel gets consumed , the fuel is replaced by air as dielectric and there is a change in capacitance. So , the remaining fuel in the service tank can be calculated on the basis of variation in capacitance. Fuel quantity gauge is of utmost importance when 1. Only service tank is left with fuel. 2. Flow metering system fails.
Continued……..
The system comprises of 1 . A capacitance based gauging probe. 2. Cable assembly. 3. Sensing amplifier box. The gauging probe assembly in the fuel tank is connected to the sensing box by means of cable assembly. Depending on the fuel level in the tank , the capacitance formed is sensed and amplified by the amplifier box and the data is sent to the electronic display in the cockpit.

AUTOMATIC FUEL CONTROL SYSTEM Automatic control manages sequence of fuel flow to/from various tanks during refueling as well as consumption.
The fuel from all the five tanks is taken in such a way that the aerodynamic balance of the plane is not disturbed.
This is done with the help of automatic control system.
Fuel from a certain tank is not taken all at once. After taking a certain quantity of fuel from one tank, the valve is closed and then fuel is drawn from another tank.
So, the sequence of fuel flow from various tanks is decided by automatic control system.

BRIEF DISCUSSION OF COMPONENTS
Signaling Transmitters(DSMK) These are sensors for sensing the fuel levels in various tanks.Magnetic operated level switches of these probes generates signal at one particular level of fuel.
Signals generated by these sensors act as an input for automatic control portion.
6 types of such sensors are fitted in various tanks.
FUEL FLOW TRANSMITTERSThese are impeller type of sensors which produce electrical 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 TRANSMITTERS These are sensors for computing fuel quantity in service tank. Capacitance of these probes change with variation in fuel level in tank. Resultant capacitance acts as an input for computing fuel in service tank.
Fuel Flow Unit Computes quantity of total fuel available in aircraft based on signals from sensors which are impeller type fuel flow transmitters and temperature probes.
It delivers the information to following instruments: 1. Refueling Control Panel 2. Stand By Equipment (SBI) 3. Complex Information Signaling System 4. Flight Data Recorder (FDR) 5. Integrated System (SOS) 6. Transponder
Fuel Quantity Unit Computes quantity of fuel in service tank based on signals from fuel quantity transmitters and temperature probes.
It delivers the information to following instruments: 1. Refueling Control Panel 2. Stand By Equipment (SBI) 3. Complex Information Signaling System 4. Digital Light Indicator
It gives warning signal to pilot for residual fuel of 1500 Kg in main tank.
Digital Light Indicator It is an electronic display device in cockpit. It continuously displays fuel quantity of service tank.
Semiconductor Relay Control Unit It is a part of automatic control portion. It works as an amplifier and a switching device for the signals required for opening and closing of valves of various tanks in aircraft.
