    Not sure how much Russia will allow France to take part in FGFA, there is bad blood between them now.

    the FGFA is totally Indian, as Su30 was updated here then, same way the T 50 will be changed to FGFA with each & every thing IAF wants, it will be fitted in, be it be french or from Israel .... surely not from USA

    no no not at all

    US needs to put its feet in the door be it be fighters for IN or IAF .

    with EMALS the door will open.

    we need & buy a few $ 100 billions over next 10 15 years .

    US will want to have it all ....... but ............... they r still ringing the bell .................. waiting for that door to open.

    man if EMALS or F22 or B2 or that laser gun can open the door .... then i think they will offer them all.

    If a 3.9 meters long engine can be fitted in, a 3.5m one is not a problem...

    Main problem is that Kaveri is a little bit bigger in diameter (+20mm nearly), and the center of gravity is not the same also.

    BUT, but Tejas was studied for Kaveri so I think these 2 problems are not.

    If you study the stability of an aircraft, you will realise that between a longer engine and a compact engine, the CG shift is negligible provided the weight difference is not huge.

    The CG of a Jet engine is around 40% of its length for non afterburning engines as the Fan+Compressor has the maximum weight. For an afterburning engine, the CG is around 45% of the length of the engine. Now let us take the case study of F404 with 3.91m and Kaveri with 3.5m with equal weight of 1050kgs.
    The CG of F404 will lie 1.564m from rear and that of Kaveri will lie at 1.575m of the engine length. For an RSS aircraft, this rearward marginal shift in CG will allow for better agility.

    Manohar Parrikar confirms French help for revival of Indian Kaveri engine
    By Manu Pubby, ET Bureau | Updated: 14 Feb, 2017, 17:59 hrs IST
    • Rafale fighter deal likely to be used to fund it, Defence Minister Manohar Parrikar has said, adding that India will requires a large quantity of engines in the future, including over 5,000 for helicopters itself.

      Parrikar said that French firm Safran - which has developed the M88 engines for the Rafale - will be using technology from its engines that go on the Rafale to revive the Indian project. The minister has confirmed a story first reported by ET on July 4, 2016 about the Kaveri revival plan.

      As reported by ET, leading manufacturer Safran has finalised a $2 million consultancy agreement to revive the project for combat planes and unmanned aircraft. French experts have studied Kaveri gas turbine project -- which was stalled in 2014 -- and have draw a joint development plan.
    • France has offered a one billion euro investment to revive the combat jet engine project, proposing a joint development plan to use offsets credits that will come from the Rafale fighter jet deal.

      The Rafale deal has a offset obligation of 50 per cent of the contract cost, which translating into over 3 billion euros. Several rounds of discussions have already taken place between French company Safran and Indian developers since January.

      The Kaveri engine project was more of less abandoned for aviation use in 2014 due to power shortcomings. While the consultancy agreement will lead to a detailed plan, initial assessments by French experts has brought out that 25-30 per cent more work is needed for it to get combat worthy.

    With French company Safran agreeing to help India revive its Kaveri combat jet engine project, a senior DRDO official said on Thursday they hope to fly the engine in the next Aero India. The issue of safety is involved since the engine is supposed to be used in Light Combat Aircraft, Defence Research and Development Organisation’s Aeronautical Systems Director General C.P. Narayanan told IANS on the sidelines of the Aero India 2017. “Safety is a concern if you are flying a single-engine aircraft; if it is a twin engine, there is no problem. Reliability and safety are foremost concerns. Now, someone has to audit this engine and say it is safe for flying.” The Kaveri engine development project was sanctioned in March 1989 but dropped in 2014-15 after repeated failures. The project for an indigenous engine was helmed by the Gas Turbine Research Establishment (GTRE) of DRDO for mastering one of the most complex technologies. Narayanan said assistance is required for defining the ‘flight envelop’ for the indigenous engine. “That envelop development related to safety is very critical, we are taking help now,” he said. A flight envelop describes its safe performance limits in regard to factors like minimum and maximum operating speeds and elevation. He said an updated version of the engine will be developed, which will be called K9. “We have up to now K8 (prototype), now we are going to call it K9,” he said. On Tuesday, Defence Minsiter Manohar Parrikar said the Kaveri fighter engine project will be revived and that the DRDO is in discussions with Safran as part of offsets under the Rafale jet deal, inked between India and France in September 2016. In a written reply to the Lok Sabha in December 2016, Minister of State for Defence Subhash Bhamre had called the effort of the GTRE in developing the engine as “an attempt to mastering one of the most complex technologies”. The minister said the altitude test and flying test bed trials for the engine had been completed and other developmental problems were being addressed to make the engine flight-worthy through in-house efforts as well with assistance from abroad.
