India's indigenous light combat aircraft (LCA), the Tejas, was flown in formation at the Aero India show this month, with a two-seat version was on display in the static park. The Tejas MkI received initial operational clearance in January, and full operational clearance is due next year. Changes in weapons, sensors and avionics will be made according to Indian Air Force (IAF) requirements. The Tejas MkI is powered by a single GE 404-IN20 engine. The Mark II version, displayed at the show in model form, is expected to have a GE F414-IN S6 engine. However, the Defense Research and Development Organisation (DRDO) has not yet announced the finalization of this contract.
Development of the indigenous Kaveri engine for the LCA has been problematic. DRDO director general Dr. V K Saraswat said that a joint venture with Snecma to produce an 18,000-pound-thrust version of the Kaveri engine is proceeding successfully, and will incorporate the French companyπs single crystal blade technology.
