Kaveri Engine

[LondonParisTokyo]

Everything has a cost. A high upfront cost usually pays off after some time. Definitely the case with a domestic testbed

 

[Dark Sorrow]

How much does it cost approximately? I mean it can't be that expensive. If we have to become self reliant in Jet Engine technology we have to have a test bed. That test bed can also be utilized for high bypass engines tests too when we start building transport aircraft on our own.

A single test bed will cost around $500 million. This include the aircraft with structural modification, airworthy certification, pilot training, sensors and test equipment.
However this will only be for Kaveri and engines having similar characteristics (physical, fluid-dynamics, etc).
The same test-bed can't be used for high bypass engines tests. Either will have to modify the existing test-bed or buy a new test-bed completely.

This is peanuts. Look at the complete development cost of Kaveri. Domestic testbed saves time on testing, saves time on renting foreign equipment

 

[Blademaster]

Is that for the drone program or is it actually the jet version? Would be great if it was the jet version. If it is only for the drone program, I'm like eh

So why can't we modify some Air India passenger jet or even Embraer Jet which we have in our inventory?

No, you can. But in order to do that, you have to change the structure of the plane, also the internal wire, electricity supply and installation of other machines, so you either get assistance from the plane manufacturer at massive cost or taking the huge fault risk by doing it yourselves (no one can).

Peanut? Well, only look at this field, yes, it is. But don't forget there are quite a lot other programs are also asking for money. Even if every one is only asking for peanut, together the demand is more than any government can afford. Keep this in mind: the demanding is unlimited, the resource is always limited.

By the way, today, India is only having one jet engine program, that means more than 90% of time, this test bed will stay on the ground. No one in his right mind will buy a test bed for such low usage.

Is there no other way to simulate high altitude testing? Even if the test bed is expensive it's something necessary for self reliance. The cost is a necessary evil which we have to bear for our own security.

Their are programs available like GSP or PROOSIS where by you can mathematically simulate high altitude testing which is also done by GTRE but live testing is needed where production and manufacturing limitations and defects also come in play and need to be analyzed.

 

[Super Flanker]

So from what I understood from reading the threads, we have been able to successfully able to demonstrate usable dry thrust Kaveri. Is there any reason we haven't seen this engine being used in some subsonic applications? Like bombers whose engines generally are made from the traditional engines without the hot core??

I had heard some news reports few months back that Kaveri Dry thrust engine can be used to power our upcoming Ghatak UAV.

In 2015, our than Defence Minister Manohar Parrikar had said in the Rajya Sabha that Ghatak will be powered by a dry Kaveri engine variant, which will have a thrust of 52 kilonewtons.

Very funny.

Lack of testing facility delays Kaveri dry engine, meant to power India’s first stealth unmanned combat aerial vehicle

Once the Kaveri Dry engine clears these simulated high altitude tests, GTRE will position the engine in the flying test bed (FTB), which is a modified Ilyushin (Il)-76 fixed-wing, four-engine turbofan aircraft.

What nonsense is this ! How many times the same circus keeps repeating right since LCA days ! Effing babus never learn, must first invest in a flying test bed asap, and no its not cheap ! Jet engine dev never is

Recently defense decode said its going through ground testing

ENGINE DEAL FOR AMCA COULD BE FINALISED DURING PM MODI'S UPCOMING VISIT TO FRANCE
Talks on with French firm for making its engine in India


In a major development for India’s fighter jet program, talks are in final stages to co-develop an engine with French major Safran. These engines will be used to power the Advanced Medium Combat Aircraft (AMCA), a fifth-generation fighter jet being designed and made indigenously.

Prime Minister Narendra Modi is expected to travel to Europe from May 2 to May 6 to have bilateral meetings with re-elected French President Emmanuel Macron and German Chancellor Olaf Scholz apart from addressing the key India-Nordic summit in Copenhagen. With Macron getting re-elected as French President for the second term with a resounding vote, PM Modi is expected to drop by in Paris to meet and greet the leader of one of India’s closest bilateral partners.

The French company, which has an existing partnership to make engines for helicopters in India, is ready to make the engines in India and as per India’s requirements, sources said, adding that the final round of discussions was on.

The AMCA is proposed to be a twin-engine stealth fighter jet that will come in two variants – stealth and non-stealth version.

According to ADA the final configuration of the AMCA has been frozen (finalised) and by year-end, the CDR (Comprehensive Design Review) is slated to be completed.

A successful CDR means its design has been found viable.

The DRDO had announced the use of the US engine would be an interim measure until India developed a higher-thrust power plant. The F414 has a thrust of over 90 kilonewton (kN), while the DRDO is looking to develop an engine with 110kN of thrust with foreign assistance. Higher thrust allows heavier take-off weights, enabling carriage of more fuel and weapons. It also endows an aircraft with greater manoeuvrability, a major advantage in aerial combat and evading anti-aircraft missiles.
