getting massage is not illegal in India, infact having sex is not illegal in India only paying for sex is illegal. If he could deliver Kaveri, we would love to send some good masseurs to suit his taste.

Paying for sex should also be legal, particularly when we pay lawyers to lie for us!

shit... i ve been talking about snecma kaveri engine like 2-3 years, and possible induction,
and here comes the news NO AGREEMENT YET.....


it looks LCA ENGINE and RADAR are definitely linked to MMRCA deal...

Railways keen on using Kaveri engines developed by DRDO: Parliamentary Committee

NEW DELHI: The Indian Railways has shown keen interest in the Kaveri engine, which is being developed for fighter aircraft, to power its trains, the Defence Research and Development Organisation (DRDO) has told a Parliamentary Committee.

"A request has come from the Indian Railways to know that whether Kaveri engines can be used for powering locomotives," DRDO told the Standing Committee on Defence.

In its report tabled in Parliament last week, the Committee said the DRDO has plans of producing Kaveri engine in large number in collaboration with Bharat Heavy Electricals Limited (BHEL).

DRDO officials told PTI that the Railways were showing keen interest in the programme as gas-turbine engines were the best and most fuel efficient.

"Though the engine is being developed for fighter aircraft, it can also be used on other platforms such as ships and heavy vehicles," they said.

Kaveri engine is being developed for the Light Combat Aircraft (LCA) and for the future ventures of the DRDO in the field of aeronautics at its Bangalore-based lab Gas Turbine Research Establishment (GRTE).

The engine recently successfully completed its first test-bed flight test in Russia and has completed other stages of development, including component testing, safety tests, ground based and endurance tests.

The engine has been put through a series of more such tests both in Russia and GTRE facility to prove its reliability, airworthiness and safety.

In the last two decades, DRDO has has spent close to USD 455 million on development of the Kaveri engine.

The indigenous fighter aircraft engine programme was first started in 1986 but suffered delays and cost over-runs due to the technology denial regimes in the 90s.

great god speed the work on kaveri and kick out the GE as early as possible

since the dry thrust of kaveri is nearly on par with those of foreign engines of similar class,nearly on par with the fuel efficiency and being much cheaper and being made in desh will make it best suitable for our needs. I think GTRE should grab the oppourtunity with both hands and do the needful at the earliest............

bhai kya scene hai railway ka.... desh ka rail.. indian rail ab jet engine laga kar track pe chalega ya hawa main udega??

It seems that kaveri has met a dead end with thrust increase for now {should atleast increase overall pressure as an incremental change } but they should decrease weight to make it fit for AJT and LCA Trainer.

 

[rudresh]

Now GTRE should think about titanium and its alloys,as titanium sponge is being produced in desh to decrease the weight of kaveri,they should go for different designs and modifications for ships and high bypass versions for transport and cargo planes and better team up with HAL for producing the Turboprops.

DRDO says its Kaveri engine can power combat drones, warships and possibly trains

So what if it cannot power fighter jets as of now, it's perfectly suitable for combat drones, warships and possibly even trains! Or, so the never-say-die Defence Research and Development Organization (DRDO) is now proclaiming as far as its Kaveri engine is concerned.

DRDO officials say the Kaveri aero-engine, which incidentally is over 22 years in the making by now with a sanctioned cost of Rs 2,893 crore, can power unmanned combat aerial vehicles (UCAVs) because they "do not require the kind of higher thrust" needed for the indigenous Tejas LCA (light combat aircraft).

"Nine prototypes of Kaveri engine and four prototypes of Kaveri Core (Kabini) engines have been developed with over 2,000 hours of testing...the engine is proven with almost 80 kilonewtons (kN) of thrust now, which is enough for our UCAVs (Tejas requires 90 kN)," said an official.

This comes even as DRDO has now begun preliminary work on developing stealth UCAVs, under the secretive 'autonomous unmanned research aircraft' programme. This UCAV will weigh less than 15 tonnes, fly at altitudes of 30,000 feet and fire missiles and bombs with precision, as earlier reported by TOI.

DRDO has also come up with a modified Kaveri version, by "designing a free-power turbine to generate shaft power", for propulsion of warships. The Navy, as per DRDO, has shown "a lot of interest" in the engine which has a 12 MW power output.

"With Kaveri, we have proven several gas turbine technologies for a variety of applications. Indian Railways is also interested in knowing whether Kaveri can be used for powering trains," said the official.

DRDO is now also trying to tie up with French company Snecma to jointly develop the "90kN thrust class of upgraded Kaveri engines" for the future requirements of IAF. But the fact remains that the Kaveri project's dismal performance has forced India to ink a $822 million contract for 99 General Electric's F-414 engines, with an option to go for another 49 engines at a later stage, to power the Tejas Mark-II version.

While the first 20 Tejas will be powered by GE-404 engines, the next six Mark-II squadrons (16-18 jets in each) will have the new more powerful GE F-414 engines. Under the LCA project, which itself has been 28 years in the making with an almost 3,000% jump in overall developmental costs, IAF hopes to have its first two fully-operational Tejas squadrons based at the Sulur airbase (Tamil Nadu) by 2015 now.

^^^ Previously, they said kaveri is gonna power LCA Mark2 and then said it will power second batch of LCA Mark2 and then not meant to power LCA at all, it will power AMCA, UCAV & MALE UAV (miniaturized??).

And now say that they're going to power naval ships and trains!!! DRDO people are very clever in putting up front their failures in newer formats... Anyways, we shall conclude that Kabini core has hit a dead end in thrust ratio??

Why should we run behind French company for this too who looks for more cash always and doesn't have a parameter of relationship at all.. I think, better we shall try to make a tie up with Honeywell or pratt & whitney

Do u think that kaveri can power lca? not possible now...simply because it will be needing airframe modifications for lca {a lot more than what F414 require}again so though the engine produce 90 or above 90 kn it will not cut it......

if they would have got some foresight when they first met with failure and did the co-development with snegma they could have got an engine completely tested by now and ready for mark2 but they did not expect mark 2 at that time on seeing IAF.

prat and whitney may help but would take the rights for kaveri and they only agree for design changes and not with any high end parts............on the other hand snegma would help with the critical parts but they will force their core.........

It will be a very difficult call for GTRE to join any one, i feel it is better to go with prat and whitney since they have better engine design knowledge.......... again the engine may not give the required 90kn since metallurgical knowledge to make newer alloys is not our forefather property.

Thats why they are behind the snegma for engine parts since the core makes a great difference or else co develop with prat and whitney and get some parts from snegma or co develop and leave it to the fate and start a new engine design based on the knowledge or co develop with prat and whitney and make a new engine with snegma.

But it is better to get the design knowledge and make do with the juggad from MMRCA goodies......for the k9 { let it power UCAV & MALE UAV only } and for k10 they should go with the france as early as possible........they dont understand the frigging urgency do they? this is how they lost time and didnt got an engine for lca mark 2 if they dont learn that now they will end up with the same fate for AMCA so get the design knowledge get over the mistakes and go for a new engine with french.

Above this IAF wants an engine which fits with the LCA with minimal modifications............snegma know that it should be somewhat similar to GE414IN6 since kaveri,M88 and GE414 are much similar in design {which was one of the reasons behind kicking ej200 out for engines} they know well that the ball is in their court.............and will they be nice without good cash

I wonder why Indian railways is interested in it

8257kg comes to 80.5kn ok they have moved from 75 to 80.5kn congrats for GTRE for that what is impressive about the engine is still the bypass ratio is 0.2 and the overall pressure is 21.5 well that shows that there is a large room for the thrust increase for the engine and atleast we should get some help from EADS if typhoon is chosen day by day it dosent justify for the GTRE for going for an engine with 90kn that we are going to get after four years and after spending 2 billion.

This tie up should happen only for an engine with 100 - 110kn engine with a margin of 20-25percent thrust increase later including 3d blades like that of GE's EPE. IAF does not need 90kn anymore.

Does it look more like 82.5kN? If it is 82.5kN then that is remarkable however one should also see how much fuel it consumes to achieve that thrust!

The LCA PV-1 was built for the Kaveri and it does not need much modification. It has been stored away in some hanger awaiting the Kaveri engine. If the thrust is 82.5kN they should just stick it up the LCA and be done with it.

It don't really matter how much thrust it is rated for if it can't perform at supersonic speeds. You would be better off converting it to high-bypass ratio engines and start your commercial aircraft industry. GoI has given up on this engine for fighters. If they can use it in marine and locomotive applications, more power to them but the real money is commercial aviation.

The air passing through the duct is transonic, which means the air has to slow down to subsonic speeds before turbine entry in any fighter aircraft. Airflow is always slowed down to manageable subsonic speeds!

Also where did you read this speed issue?
