Ramana-ji, couple of points to note;
1) The Kaveri program was comatose, until the Rafale contract signed in Sept 2016. See below (written by Anantha Krishnan)...DRDO to abandon indigenous fighter jet engine Kaveri projecthttps://tarmak007.blogspot.com/2014/11/ ... andon.html
18 Nov 2014 and if you click on the link above, the author updated the article (in Jan 2015) via a link at the bottom of the page.
The Defence Research and Development Organisation (DRDO) has decided to wind up the Kaveri engine (GTX-35VS) programme, signaling an end to a desi dream of equipping its own fighter jet with a home-grown power plant. Sources in the Ministry of Defence (MoD) confirmed to OneIndia on Tuesday that the DRDO has already moved a file recently seeking the closure of the ambitious engine development project undertaken by Bengaluru-based Gas Turbine Research Establishment (GTRE).
2) By mid 2016, news reports started coming in that France offered to revive the Kaveri program. See below...France offers help to resurrect Kaveri engine for Tejashttp://www.thehindu.com/news/national/F ... 475955.ece
France has offered to help India revive the unsuccessful Kaveri engine project for the indigenous Tejas aircraft and a host of other high-end collaborations. This is a part of the offsets in the multi-billion Euro Rafale fighter plane deal, which is now in the final stages.
An upgraded Kaveri engine with 90 kN thrust compared to the existing 72 kN can be developed with French cooperation, which can eventually be used for Tejas, which currently uses an American engine.
This was a brilliant move by the French, because they knew whatever ailed the Kaveri was fixable. We bit the bullet and in Sept 2016, the Rafale deal was signed in New Delhi, between India and France.
Prasannasimha-ji did a wonderful job by posting that snippet on the Kaveri program. From 2014 to the end of 2016, there was little or no movement of any significance on the Kaveri program. In Sept 2016, the Rafale deal was signed and France promised to have the Kaveri fly by Aero India 2019. By the end of 2017, five prototypes were tested for a total of 145 hours. Safran conducted a technical audit and states that the engine has attained sufficient level of maturity.
Now GTRE could have done this themselves and saved US $1 billion in the bargain. But remember, DRDO wanted to shut down the program in 2014. Four years later, the program has done a complete u-turn. We always knew Safran would make the Kaveri work, whether they actually wanted to do it was the real proof in the pudding. And if that news snippet is correct, Safran has delivered albeit half way. The next deliverable from Safran is get the Kaveri to fly and the one after that is to get the Kaveri certified.
What exactly Safran did, we will likely never know unless we have chaiwallahs in GTRE
Audit can be anything and Katare has provided clarity on that. Now this by Prasannasimha-ji is very interesting. Safran was supposed to put the M88 core in and make the Kaveri work. But that has not happened. The Kabini core itself has been modified by Safran.
prasannasimha wrote:^ I think the Kaveri Safran has audited did not have an M88 core. It is still the original Kabini core with some modifications.
Now I will make an educated guess of my own. I believe Safran has "modified" the core to meet - at minimum - the original design specifications, which I am assuming is around 90 kN. I believe - in this very dhaaga - we came to conclusion that the M88 core cannot be installed in the Kaveri engine. Please correct me if I am wrong. But regardless, the above is even better news.
Now you make a valid point...is this help from Safran really worth US $1 billion? Please remember (I know, I sound like a broken record player)...the program was officially de-linked from the Tejas. If Safran can make the Kaveri fly and certified
- via audit, via modifications or whatever - that is IMHO a very sound investment. As per wiki chacha, we have spent more than US $640 million on the program, add another US $1 billion (Kaveri offset) and a few hundred million more and India will have spent ~ US $2 billion to date on this program. Sir - as long as the engine works - that is peanuts. The payoffs for India are huge.
Now Safran has provided its input and its report. Now the first step is get the Kaveri to fly. The next step (a long way to go for this) is certification. My lungi is ready for Aero India 2019. I will either lungi shiver or lungi dance, depending on the news
