We have already got the naval Kaveri out of this (have not heard anything else since the initial announcement of it). But it is good to have this behind us as we learn how to build a better and more powerful engine as our scientists now know what to ask/look for.

Its sheer tomfoolery to think that only money motivates people as anon@14:39 thinks.

I mean, with the amount of money and time we have spent on these programs, indigenization has caused more problems than it has solved.<br /><br />Don't you think we'd do better by either following the reverse engineering approach or by privatizing the matter like the US.<br /><br />At least less public money would be wasted. <br /><br />The Tatas have already expressed their intention to get into making fighter jets. I think other majors like L&T, etc would not mind getting into joint ventures with foreign firms to come up with semi-indigenous defense products.<br /><br />PS: I don't really believe that the best Indian talent serves in companies and organisations like the DRDO.

QUOTE...http://en.wikipedia.org/wiki/Shenyang_WS-10<br /><br />QUOTE>> The WS-10 project had it roots in the earlier WS-6 turbofan which was abandoned at the start of the 1980s.[3] Development of the WS-10 started in 1987 by Shenyang Aeroengine Research Institute (606 Institute) of the China Aviation Industry Corporation. The original WS-10 was found to lack the performance needed for modern jet-powered fighters and was never used to power an aircraft. The design was modified and an improved version, the WS-10A, was tested on a prototype Shenyang J-11 fighter in 2002. <<UNQUOTE<br /><br />It is a copy/cut & paste story of WS-10.Mr. Ranoreply@blogger.comtag:blogger.com,1999:blog-8726844009873922462.post-2764315350645613432010-11-05T11:43:04.338-07:002010-11-05T11:43:04.338-07:00It is also said by gtre officials that 93% of desi...It is also said by gtre officials that 93% of desired thrust(90Kn) have been realized i.e. 83KnAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-8726844009873922462.post-86143576991167474362010-11-05T11:39:00.554-07:002010-11-05T11:39:00.554-07:00Hey MPtatel,
