The Aeronautical Development Agency (ADA) is giving the final touches to the preliminary design of the Light Combat Aircraft (LCA) Tejas Mk-II, scheduled to be completed by the end of March. An official told Express on Saturday that the detailed design phase of LCA Mk-II would begin in the second quarter of 2014.
A separate project team from ADA and Hindustan Aeronautics Ltd (HAL), dedicated to the upgraded version, is currently undertaking daily reviews to get the first cut of the design out by next month.
The main scope of Tejas Mk-II programme is to have the engine changed from the current GE F-404 to GE F-414. A development contract for eight engines for the preliminary design phase has already been signed with GE, with the critical design review already been completed at its Boston facility.
The Mk-II fighter will have OBOGS (Onboard Oxygen Generating System), which is being developed by Defence Bioengineering and Electromedical Laboratory, a Bangalore-based Defence Research and Development Organisation lab. “Currently, the ground development is over for OBOGS and the systems are undergoing various stages of qualification process,” an official said.
Tejas Mk-II will have a unified electronic warfare system aimed at detecting and ducking enemy radar and later jamming it. “It is likely to be the most maintenance-friendly aircraft in its class and all equipment onboard can be easily removed and re-installed smoothly. The Tejas MK-I has some scope for improving the maintenance aspects, which is being addressed in Mk-II,” the official said. “The Mk-I has some dead weight in the form of lead plates installed to balance the aircraft which will disappear in Mk-II. It will also have considerable amount of extra fuel capability in operational clean configuration,” he added.
The point performance of Mk-II will be higher than Mk-I, which means the aircraft will have better rate of climb, transonic acceleration and turn rates. The new version will have an in-flight refuelling system and the ADA-HAL combination is planning to take a new route for Mk-II production.
“We are going for the DFMA (Design for Manufacturing and Assembly) technique for the production of Mk-II. The DFMA concept will be used for the first time for an Indian aviation programme, which will decrease the production time and cost, also increase the quality quotient,” the official said.
With the avionics systems changing at a faster rate leading to technology obsolescence, the makers of Tejas have an uphill task of making the fighter contemporary even in the 2025s.

Considering it look 3 years to redesign JF-17, it should take about this same amount of time to design Mk 2 from Mk 1.
