Light Combat Aircraft 'Tejas' in R-Day Parade

Asian Defense News: Bangalore: Indigenously developed Light Combat Aircraft (LCA) 'Tejas' will be seen during the Republic Day Parade in New Delhi on January 26.
Official sources here today said ''the prestigious ''TEJAS'' will be seen in the Republic Day Parade for the first time in New Delhi.''
The two-seater indigenous LCA made its maiden flight at the Hindustan Aeronautics Limited (HAL) Airport here on November 26, 2009.
The successful flight flew at an altitude of nine km and attained Mach 0.85. The prototype was flown by Group Captain Ritu Raj Tyagi of the National Flight Test Centre with Project Director (Flight Test) Air Commodore Rohit Varma in the rear.
The IAF is reported to have a requirement for 200 single-seat and 20 two-seat conversion trainers, while the Indian Navy may order up to 40 single-seaters to replace its Sea Harrier FRS.51 and Harrier T.60.
The LCA naval variant is expected to take to the skies by 2009. Recent developments suggest that the aircraft will be inducted into the Indian Air Force by end of 2010 or early 2011.
During its sea level flight trials off Goa during December 2009, Tejas notched a speed of over 1,350 km per hour, thus becoming the first supersonic fighter being manufactured indigenously by Hindustan Aeronautics Limited.

India developing Next Generation Fighter Aircraft

Asian Defense News: Recently when Requirements of MCA now re-named to NGFA (Next Generation Fighter Aircraft) by Indian Air force was made public in section of media , IAF clear dedicates what it wants for NGFA and seems to leave very little room for developers ADE and other DRDO labs .
IAF seems will not compromise on the aircrafts capabilities from the start.
For years NGFA was rumored to be a strike aircraft with secondary role of Air defence capabilities.
Now IAF wants a fully multirole Aircraft with almost all the technology which only a 5th Generation Aircraft like Pak-Fa which India is partnered with Russia for its development will have, India’s contribution to Pak-Fa is limited to sub-system of it avionics and its core software very similar work which was done with Sukhoi-Su30 MKI.
Other then Avionics which can be further developed from Tejas MK-II platform they are tones of other things which NGFA will need to make it truly a 5TH Generation Aircraft .
IAF seems to be clear that it wants most of the Avionics and Engine for NGFA to be indigenous, Specially the AESA Radar; it seems IAF will not settle for AESA which has been developed by LRDE for Tejas Mk-II, it want to be more sophisticated than the Current AESA technology what LDRE is working on and better Avionics and Self-defence systems for the aircraft which will take lot of time unless similar Pak-Fa Avionics package is chosen.
The Kaveri-Snecma Engine based on core of M-88 has been seen has the possible engine which will power NGFA, Details of this engine is still not clear and what level of Technology French will bring is also crucial, GTRE failed to develop current Kaveri engine in time to power Tejas Combat aircraft .
The new engine should be based on consultation with IAF to avoid future disappointments and should be ready in time to power NGFA which will have a tech demonstrator, three prototype vehicles and two production jets. No intermediate Engine has been sought, Kaveri-II have to be ready in time for NGFA to make its first flight.
Stealthy Airframe Requirements seems to have thrown out any DRDO’s plans of having Aircraft with low Stealth characters, it wants Stealthy Airframe from the start and Current level of technology in India does not have such high end materials, composites and radar observing airframe materials and paints.
Wind-tunnel model which was displayed at Aero India 2009 of MCA will need designs changes to meet IAF’s demand of full Stealthy Airframe, while wind tunnel model seemed like Aircraft with Stealth features but not fully stealth aircraft.
Time frame set by ADA is again over ambitious. ADA plans to have the first test flight of the NGFA by 7-8 years, once go head is given which may come by end of 2010, this is simply not possible since most of the technology required for it is still not in pipeline, since various Labs will be working on it any delays by any Lab will affect the schedule flight plan and again it will look similar way which LCA was made to go.
Consultancy and joint development of various systems should be considered to meet the deadline for NGFA’s first flight; Aircraft should be developed with possible export market in mind. To give air forces around the world a cheap and high technology 5TH Generation fighter this can compete with American and Chinese aircrafts in future.
