Actually it's a good news for indian pilots.
and good news for GE as well

another failure by india.
all talk.
if it was not operational we would not have this video would we?
What's wrong here ??? Why is everyone dancing here on Kaveri ???
Ok Kaveri failed to achieve its main objective - LCA. No one should deny.
There are plans to use this for Locomotives and marine use.
JV with French company on the Engine will give LCA it's engine for MLU and India very needed experience to start again new project.
People here are talking like they never failed to achieve anything. China member you all know what your WS-xx is made from.
And Martian - US flagger - failure isnt alien to USA either. So SFU
Kaveri is not a failure. It successfully paid thousands people handsomely. My friend's company got tens of millions for doing nearly nothing. That was a huge success. Carry on.
Hey Ws- 10 engine, have you looked at yourself in the mirror ? You may see Soviet Saturn turbofan in the reflection !!
Jet Engine, excellent job Martian219 tons (or 190 KiloNewtons) of wet thrust (which means with afterburner)
19.1 tons (for F-35/JSF) - Pratt & Whitney F135 (in service 2009 - dates are approximate).
Important note: F135 has a high bypass ratio and F-35 cannot supercruise.
18 tons of wet thrust
18 tons (for J-20) - China's WS-15 ("Initial Operational Capability"/IOC 2020. Successful prototype operation in 2005). WS-15 has a low bypass ratio and J-20 can supercruise.
15 tons of wet thrust
15.6 tons (for F-22) - Pratt & Whitney F119 (IOC 2004). F119 has a low bypass ratio and F-22 can supercruise.
15.5 tons - China's WS-10G (Global Security believes it was installed on J-20 prototype in 2011)
14 tons of wet thrust
14.5 tons (for T-50/Pak-Fa) - AL-41F (in service 2010)
13 tons of wet thrust
13.2 tons (for J-10, J-11, and J-15) - China's WS-10A (in service 2009)
13.2 tons (for Russian Su-30) - AL-31FM1 (in service 2007)
12 tons of wet thrust
12.5 tons (for J-10A) - AL-31FN (in service 2002)
8 tons of wet thrust
8.9 tons (for Eurofighter Typhoon) - Eurojet EJ200 (in service 1991)
7 tons of wet thrust
7.5 tons (for French Rafale) - Snecma M88-2 (in service 1996)

Citation for high bypass turbofans and subsonic speed from Global Security.
Military Aviation Engines
"High bypass turbofans, meaning bypass ratios in the range of 5 to 9, power virtually all transports designed to cruise at high subsonic speeds. High bypass ratio engines provide increased takeoff thrust, low environmental noise, and low specific fuel consumption. The development of the first high bypass ratio turbofans, the TF39 for the C-5A and the JT9D for the Boeing 747, required nearly doubling the cycle pressure ratio from the 12:1 of the JT3/J79 series of jets, and increasing the turbine inlet temperature.
The newest high bypass turbofans have cycle pressure ratios greater than 40:1 and have been made possible by advancements in high temperature materials and cooling technology. In a general sense, increases in hot section materials capability and turbine cooling techniques have paced the development of high pressure ratio engines. Today, turbofans range in size from small missile engines by Teledyne and Williams International, to behemoths in the 100,000 pound thrust class for large transports."
Secondary citation on high bypass ratio turbofan engine:
Overall pressure ratio - Wikipedia, the free encyclopedia
"Military engines are often forced to work under conditions that maximize the heating load. For instance, the General Dynamics F-111 was required to operate at speeds of Mach 1.1 at sea level. As a side-effect of these wide operating conditions, and generally older technology in most cases, military engines typically have lower overall pressure ratios. The Pratt & Whitney TF30 used on the F-111 had a pressure ratio of about 20:1, while newer engines like the General Electric F110 and Pratt & Whitney F135 have improved this to about 30:1.
An additional issue is weight: a higher compression ratio implies a heavier engine, which in turn costs fuel to carry around. Thus, for a particular construction technology and set of flight plans an optimal overall pressure ratio can be determined."
[Note: Thank you to ChineseTiger1986 for highlighting the issue of high bypass ratio for non-supercruising F-35 and low bypass ratio for supercruising F-22 and J-20.]
not really a failure. india never had any serious homegrown jet engine program. the kaveri is made up of parts from all over places, even the testing is done in another country. india is still incredible..
Nope I don't believe its a failure, as long as we can extract as much from Kaveri, it isn't a failure.
U may think that it is just wishful thinking but it is still true.
Failure is another stepping stone to success......
kaveri is a total and utter failure. no amount of spin you put on it will save face.
this is humiliation of the highest order for the indians and their laughable defence industry.
talked a big talk as usual, and then fired blanks as usual. thats an indian trademark.
india is such a corrupt country nothing will ever get done there.
if india could reverse engineer, they would do it gladly to study and help their own industry which will help india become self sufficient in weapons systems and save billions of dollars. but the fact that india cannot even reverse engineer shows how backward indian industry and knowledge is.
and forget about R&D, india is multiple generations away from doing anything innovative.
kaveri engine failure just exposes to everyone the real state of indian military industry.
US had put sanctions on us when we did our nuclear tests in the hope of crippling our economy, and now we are the 3rd largest economy in the world.
SO BOOYAH....................
India is the 11th largest economy not 3rd.
