GTRE Kaveri Engine

once the deal is officially signed / disclosed ,

we will know Ashish info s are right or wrong , if right then how far ahead he has given Us.

lets wait for it.

It's not my Theory, it's not a hope it's something existing and tested, and which was proposed to UAE.

There is the same bypass ratio 0.3 And Safran said it's the same core. The new dimentions are slighty bigger but fit inside Rafale without modifications, only Intake need some very light modification.

It might be possible, but then it might decrease the engine life and increase LCC (Life Cycle Cost)!!!

Due to improved technology, at the time of this proposition the choice was:
  • Improve the service life and decrease the LCC by 60%
  • Or improve the Thrust from 7.5 t to 9 t with the same service life and the same LCC (M88 9t).
France choose the second approach. But M88 LCC and service life is now exceptional.
To day there is again an improved technology available and again we have the choice between an improved thrust at 8.3t without specification changes of dimentions, or an improved thrust at 10 t in the dimention of the M88 9t, or to improve again LCC and service life.

As of now it is a speculation. Livefist did not get any data about it and hence they can't tell how much cost or what exactly it is. France had stated that consultancy for Kaveri had been sought for 2 million dollars.

Here is one article which states that a 2 million dollar contract has been finalised. whereas 1 billion dollar contract is under negotiation with finalisation not yet certain:

French boost to jet engine plan, Kaveri project being revived
NEW DELHI: India’s quest to develop its own fighter jet engine got a leg up after a $2-million consultancy agreement was finalised with leading French defence manufacturer Safran to help revive the Kaveri project.

The project stalled in 2014 after the Kaveri gas turbine engine developed for combat planes and unmanned aircraft was unable to provide the required power thrust — a fact French experts expect to correct after study.

Initial assessments by the French company show that 25-30% more work is needed for the Kaveri engine to be combat-worthy.

A detailed joint development plan will be drawn up that could use offset credits — the obligation is 50% of contract cost, which translates to over 3 billion euros — coming from the Rafale fighter jet deal.

As reported by ET in July, France has offered a 1-billion euro investment to revive the project. Several rounds of discussions have already taken place since January between Safran, which has developed the M88 engines for Rafale, and Indian developers.

Apart from the initial consultancy fees, India may not need to spend on development as the French side has proposed to make the Kaveri flight-worthy within 18 months for integration into the Tejas Light Combat Aircraft by 2020.

Manu pubby, the one whose article you quoted last time also has stated the same in another article (self-contradiction?):
French boost to jet engine plan, Kaveri project being revived

Statement of Macron who arrived in India recently stated that the negotiations are going on:

"The leaders noted ongoing discussions between DRDO and SAFRAN on combat aircraft engine and encouraged necessary measures and forward-looking approaches to facilitate early conclusion," the joint statement said.

In a series of slides accessed by Livefist, the contours of the ‘Make in India’ elements of the Rafale deal stand revealed for the first time. The details that follow pertain principally to the Rafale platform itself, and doesn’t include the $1-billion partnership between France’s SAFRAN and India’s DRDO for the Kaveri turbofan engine, a major thrust area for both countries that will also count in the offsets program.

India’s stalled Kaveri gas turbine engine developed for combat planes received a major boost after leading French defence manufacturer Safran agreed to help revive the Kaveri project and make it combat-worthy in 18 months was cleared by Ministry of Defence (MOD) as offset obligation on 36 Rafale fighter jet deal.

Kaveri engine powered LCA-Tejas by 2018-19 could be reality – Indian Defence Research Wing
Negociation are going on to use the results of the development, but the development have started long ago, we even had given a link showing the profile needed to lead the project as described by Safran in it's research of such a profile.
 
That is something I know. But the kaveri engine was only sanctioned on paper. The financial crisis of 1989-1991 due to USSR collapse had taken a toll on India. Also, India only had access to the older generation engines technology till then, primarily the MiG21 R25 engines and the needed expertise for a next generation engine did not exist. India experimented with turbojet engines and various other forms in the early 1990s due to lack of expertise. The metallurgy of single crystal or directionally solidified blades had to be taken up first before delving into the manufacturing of next generation engine.

Combination of the two factors delayed the Kaveri engine beginning to 1995. It is only then that India actually started the program of the current Kaveri engine. The prototype kabini core ran in 1996 for the first time, but was not yet successful.

So, when one speaks of Kaveri engine development, one must begin from the day when the current model of engine started, which is 1995, not when the project of engine development started.

The program is two decades late. So why it missed 96 deadline doesn't matter. And don't write about how we didn't have tech then, its common sense. The point is that they promised to deliver on unreasonable timelines and failed continuously. So making similar claims don't cut it.

Actually, the project did not start till 1995 mainly because of political reasons. We are only evaluating the technical performance. The political reasons from 2008-2014 also have to be considered. The timelines were unreasonable only to some extent but the political aspects are to be excluded. Only technical aspects are to be evaluated. When timelines are specified, it is assumed that all clearances and funding will be provided without hiccup. Just look at fund requested and fund released timelines for better evaluation of political delays

When you BS at least take time to come up with some source. Would you? GTX37-14U first ran in 1977. They know very well what they are getting in to by 1986 when it was proposed.

First Kabani core ran in 1995. Did they make it out of thin air without any funding? 'evaluating the technical performance' what does that even mean ?

Why do you have to comment on every subject under the sun, when you miss basics of it?
