My Experiences

Both Navy and Indian Air Force are going to need a fighter jet to secure our skies both near land borders and maritime coast. This can be the  main peace time  workhorse to guard Indian skies.   Navy calls its version Twin Engine Deck Based Fighter (TEDBF) , while Air Force can call it as Medium Weight Fighter (MWF) or Omni Role Combat Aircraft (ORCA). Here, the need is to make a fighter using the existing research on Tejas Mk2 and AMCA. We are reaching the goal of making our own Multi-role fighter with Tejas Mk 2. At present it has been designed to be a single engine jet with General Electric F414-GE-INS6 turbofan, 58.5 kN thrust dry, 98 kN with afterburner. The present expected weight of Tejas Mk2 is as follows: 1. Gross Weight: 11,300 kg 2. Max Take Off Weight: 17,500 kg. That means payload capacity is 6,200 kg. But, Tejas Mk2 being a single engine fighter cannot be used by Navy as Twin Engine Deck Based Fighter. Similarly, Air Force cannot make Mk 2 in larg...

We are reaching the goal of making our own Multirole fighter with Tejas Mk 2. At present it has been designed to be a single engine jet with General Electric F414-GE-INS6 turbofan engine. This engine has 58.5 kN (13,200 lbf) dry thrust and 98 kN thrust (22,000 lbf) with afterburner. The present expected weight of Tejas Mk 2 is as follows: 1. Gross Weight: 11,300 kg 2. Max Take Off Weight: 17,500 kg. That means payload capacity is 6,200 kg. Now this  General Electric F414  engine has a dry weight of 1,110 kg. Its thrust characteristics are sufficient for our expected Tejas Mk 2 aircraft. But if we have a twin-engine version then the range and reliability of the aircraft can be increased along with its size. The present wing area is 44 sq.m. Let us consider if we use our own Kaveri GTX-35VS engine. Its weight is 1,236 kg. With two engines total weight of engines will increase to 2,472 kg. While total thrust will be 104 kN dry to 162 kN with afterburner. This makes the max t...
