Why in News:
- India and France are going conclude a deal, for the joint development of a 125KN engine for the indigenous fifth generation Advanced Medium Combat Aircraft (AMCA).
- AMCA will be a single-seat, twin-engine, stealth all-weather swing-role fighter aircraft.
- The AMCA design is optimised for low radar cross section and supercruise capability.
- It would be a twin engine stealth aircraft with an internal weapons bay and a diverterless supersonic intake, which has been developed for the first time for which the design is complete.
- It will be a 25-tonne aircraft with internal carriage of 1,500 kg of payload and 5,500-kg external payload with 6,500 kg of internal fuel.
- The AMCA which is intended to perform a multitude of missions including air superiority, ground-strike, Suppression of Enemy Air Defenses (SEAD) and electronic warfare (EW) missions would be a potent replacement for the Sukhoi Su-30MKI air superiority fighter, which forms the backbone of the IAF fighter fleet.
- The AMCA will have stealth and non-stealth configuration and will be developed in two phases, AMCA Mk1 with existing GE414 engine and an AMCA Mk2 with an advanced, more powerful engine.
- There are two primary approaches to making a military platform more stealthy.
- Geometric stealth: the aircraft’s form is angled in such a way that maximum radar waves are deflected away, reducing the radar cross-section.
- Material stealth: The aircraft is made of radar-absorbing materials, which absorb radio waves and so reduce the radar footprint.
- India has in the past unsuccessfully attempted to indigenously design and develop a jet engine for the LCA under the Kaveri programme sanctioned in 1989.
- The Shakti engine, which powers the indigenous Advanced Light Helicopter and its later variants, is a joint development between Safran and HAL.
