  7. 7. SUKHOI-30 MKI<br />
  8. 8. Sukhoi Su-30 MKI<br /><ul><li>The Sukhoi Su-30MKI has been jointly-developed by Russia's </li></ul>Sukhoi Corporation and India's Hindustan Aeronautics Limited<br /> (HAL) for the Indian Air Force (IAF). <br /><ul><li> It is a heavy class, long-range air superiority fighter aircraft.
  9. 9. The Su-30 MKI is more advanced than the basic Su-30MK, the </li></ul> Chinese Su-30 MKK, and the Malaysian Su-30 MKM.<br /><ul><li> The aircraft features state of the art avionics developed by</li></ul> Russia, India , Israel , France and South Africa which includes<br /> display, navigation, targeting and electronic warfare systems.<br /><ul><li>MKI stands for "ModernizirovannyiKommercheskiyIndiski" </li></ul> meaning "Modernized Commercial India".<br />
  10. 10. General Features of Sukhoi 30 MKI<br /><ul><li>Sukhoi 30 MKI is a 4.5 generation fighter aircraft . Fifth</li></ul> generation planes are yet to come.<br /><ul><li> Cost of single Su-30 MKI is $ 35 million or Rs 1.61 billion
  11. 11. As per deal between Russia’s Sukhoi Corporation and </li></ul> India’s HAL , in the first phase, components will be <br /> imported from Russia and only assembling will be done <br /> in India.<br /><ul><li> In the second phase , there will be transfer of technology</li></ul> from Russia to India , and then both manufacturing & <br /> assembling will be done in India. <br /><ul><li> Various independent sources have claimed Su-30 MKI</li></ul> to be the most superior fighter plane in present World. <br />
  12. 12. Fuel Flow And Metering SystemIn Sukhoi 30 MKI<br /><ul><li> Fuel capacity of Sukhoi 30 MKI: 12 ton or 12000Kg
  13. 13. There are 5 fuel tanks of which one is service tank or main tank.
  14. 14. Service tank is centrally located is the most important one.
  15. 15. Fuel from all other tanks pass through service tank before</li></ul> consumption.<br /><ul><li> So in the end fuel remains only in the service tank.
  16. 16. All the 5 tanks are so placed that the aircraft is</li></ul>aerodynamically balanced.<br />TANK 3<br />SERVICE<br />TANK<br />TANK 1<br />TANK 2<br />TANK 4<br />TANK 5<br />
  17. 17. STRUCTURE<br />Fuel quantity & flow metering system can be subdivided into:<br />Fuel Flow Metering<br /> > It computes the total quantity of fuel available in aircraft.<br /> Uses impeller type of sensors.<br />2. Fuel Quantity Gauging<br /> > It computes the quantity of fuel in the service tank.<br /> Uses capacitance type electronic sensors.<br />3. Automatic Control<br /> > It manages the sequence of fuel flow to/from various <br /> tanks during refueling and consumption.<br />
  18. 18. FUEL FLOW METERING<br /><ul><li> Computes the quantity of fuel left in aircraft.
  19. 19. Based on the principle of impeller movement.
  20. 20. Impeller is a device which rotates due to the movement of</li></ul> liquid(fuel) through pipe.<br /><ul><li> One complete rotation of impeller is associated with a</li></ul> unique amount of fuel flow. This gives us the volume of <br /> fuel consumed.<br /><ul><li> So weight of fuel consumed:</li></ul> weight of fuel = volume * density<br /><ul><li> Net fuel remaining = initial quantity of fuel – fuel consumed</li></li></ul><li>FUEL QUANTITY GAUGING<br /><ul><li> Computes the quantity of fuel left in service tank.
  21. 21. It is an electronic system based on the principle of variation of</li></ul> capacitance with change in dielectric medium.<br /><ul><li> It consists of uniform cylindrical shaped capacitor with the</li></ul> fuel acting as the dielectric.<br /><ul><li> As the fuel gets consumed , the fuel is replaced by air as </li></ul> dielectric and there is a change in capacitance.<br /><ul><li> So , the remaining fuel in the service tank can be calculated </li></ul> on the basis of variation in capacitance.<br /><ul><li>Fuel quantity gauge is of utmost importance when</li></ul> 1. Only service tank is left with fuel.<br /> 2. Flow metering system fails. <br />
  22. 22. Continued……..<br /><ul><li> The system comprises of</li></ul> 1 . A capacitance based gauging probe.<br /> 2. Cable assembly.<br /> 3. Sensing amplifier box.<br /><ul><li> The gauging probe assembly in the fuel tank is connected</li></ul> to the sensing box by means of cable assembly.<br /><ul><li> Depending on the fuel level in the tank , the capacitance</li></ul> formed is sensed and amplified by the amplifier box and <br /> the data is sent to the electronic display in the cockpit.<br />Cable<br />assembly<br />Electronic<br />Display in<br />cockpit<br />Capacitance<br />Based<br />Gauging<br />probe<br />Amplifier<br />box<br />display<br />
  23. 23. AUTOMATIC CONTROL PORTION<br /><ul><li> Automatic control manages sequence of fuel flow to/from </li></ul> various tanks during refueling as well as consumption.<br /><ul><li> The fuel from all the five tanks is taken in such a way that</li></ul> the aerodynamic balance of the plane is not disturbed.<br /><ul><li>This is done with the help of automatic control system.
  24. 24. Fuel from a certain tank is not taken all at once. After taking</li></ul> a certain quantity of fuel from one tank, the valve is closed<br /> and then fuel is drawn from another tank.<br /><ul><li>So, the sequence of fuel flow from various tanks is decided by</li></ul> automatic control system.<br />

  26. 26. Brief Discussion Of Components<br />Signaling Transmitters(DSMK)<br /><ul><li> These are sensors for sensing the fuel levels in various</li></ul> tanks.<br /><ul><li>Magnetic operated level switches of these probes generates</li></ul> signal at one particular level of fuel.<br /><ul><li> Signals generated by these sensors act as an input for</li></ul> automatic control portion.<br /><ul><li> 6 types of such sensors are fitted in various tanks.</li></li></ul><li>FUEL FLOW TRANSMITTERS<br /><ul><li>These are impeller type of sensors which produce electrical</li></ul> signal proportional to the rate of flow of fuel through it.<br /><ul><li>Fuel consumed by aircraft is computed based on the signals</li></ul> provided by these sensors.<br />FUEL QUANTITY TRANSMITTERS<br /><ul><li> These are sensors for computing fuel quantity in service tank.
  27. 27. Capacitance of these probes change with variation in fuel level</li></ul> in tank.<br /><ul><li> Resultant capacitance acts as an input for computing fuel in </li></ul> service tank.<br />
  28. 28. Fuel Flow Unit<br /><ul><li> Computes quantity of total fuel available in aircraft based on</li></ul> signals from sensors which are impeller type fuel flow <br /> transmitters and temperature probes.<br /><ul><li> It delivers the information to following instruments:</li></ul> 1. Refueling Control Panel<br /> 2. Stand By Equipment (SBI)<br /> 3. Complex Information Signaling System <br /> 4. Flight Data Recorder (FDR)<br /> 5. Integrated System (SOS)<br /> 6. Transponder <br />
