Kaveri Engine

[kshkumsin]

Sir thanks but recent SEA wasp engine( latest vesion) has 85+KN thrust & even 81Kn as u mentioned is far better than 70.4KN Kaveri , my question is what is harm in reverse engineering those tech & update it into Kavery?

well it says kaveri has 81 kn

 

[Kunal Biswas]

Yes, that can be tried but even reverse engg takes lots of time and even more resources, And chance of failure are more in such process..

 

[Decklander]

Reverse engg allows you to copy design and not materials. Kaveri needs advanced materials which no one is willing to share with India.

would have got a sweeter deal had this thing done before MMRCA deal..

 

[Somreet Bhattacharya]

I hope Rafale deal includes transfer of Tech for M88 engines also. Kaveri is unique in many areas and if it comes good, it will be best in its class in the world.

But Sir,
I dont think Snecma will part with the M88 core...given that is the only thing they can ultimately extract the moolah out of India...

 

[Armand2REP]

Is there any possiblity of AL-31 technology being transfered to Kaveri, for increasing the trust? if yes how? if no, then what is purpose of technology transfer?

AL-31 is 123+KN rated engine ,HAL license produces both AL-31 & Klimov RD series then why can't few good technology go into kaveri which can improve thrust

Nothing of AL-31 is compatible with Tejas. The engine is far too large to ever scale. Russians don't want to give SCB technology.

To china bhai,
( @cir @tony4562)
What's the Thrust-to-Weight ratio of Chinese Engine (WS-10) ?
(Please dont disclose if there's a slightest bit of chance of CCP throwing you bhai's in slavery camp for disclosing it on an Indian Forum)


CHINA STRONG

Dream of fitting indigenous Kaveri engine into LCA-Tejas over

Bangalore: The dream of fitting Kaveri engine being developed indigenously into the home-grown Light Combat Aircraft LCA-Tejas appears to be as good as over.

"Kaveri engine as such will never come into LCA", P S Subramanyam, Director of Aeronautical Development Agency (ADA), a DRDO lab, which is the nodal agency for the design and development of LCA with HAL as the principal partner, told PTI here.

Noting that LCA-Mark 1 and Mark 2 will have engines from GE, he, however, said the LCA would support Kaveri engine's flight tests and demonstrations and certification.

"As and when there is support required by the Kaveri engine, LCA will give support of its flying test facilities", Subramanyam said.

He expected flying tests of Kaveri engine to lead to its fitting into unmanned air systems.

Subramanyam said Kaveri engine-fitted LCA would not go into the Services. "In the production aircraft (LCA) going into the Services, Kaveri engine will not be there".

Kaveri engine, originally intended to power the LCA, was taken up for development by Bangalore-based Gas Turbine Research Establishment (GTRE) about two-and-half-decades ago but the project has been dogged by delays, with the DRDO lab not being fully able to overcome technical challenges and development snags.

Scientific Advisor to Defence Minister and DRDO Director General V K Saraswat said unmanned air systems would see the integration of Kaveri engine for different applications.

Kaveri engine will be demonstrated on board an Indian origin aircraft, added Saraswat, also Secretary in the Department of Defence (R&D).

Meanwhile, Subramanyam said the first LCA produced by HAL would be ready in the third quarter of this year.

See when the present K-9 is put into tejas for flight certification(as per ADA chief's statement) and validated for all it's technical parameters,
it will be a very significant development,
even though it is not fit for Tejas mk-2 ,it is the prime candidate for AURA which is as important as TEJAS,

Also it gives a capability to ADA (if sane people in IAf and MOD take a serious look at it)of building a completely indigenous TEJAS mk-3 stealth variant very quickly with twin k-9 engines totaling 100 kn dry thrust with 150 plus kn wet thrust , which will give super cruise capability, without a single foreign component.

Both are strategically vital capabilities for any emerging super power besides the obvious other application for marine purpose,

If latter the lower thrust is rectified with K-10 program(international tender is called for that purpose) then during the first engine upgrade all the AURA and Tejas mk-3 variant can be upgraded with higher power k-10 engines.

The teajs-mk-3 twin engined stealth with k-9 is a fall back option if the advanced AMCA project exceeds the developmental time limit,

since Tejas mk-3 will have performance and parts commonality with Tejas mk-2 ,it can be very quickly developed within a decade at a far lower cost , it is a more logical step considering even CHINA has two stealth fighter programs.

would have got a sweeter deal had this thing done before MMRCA deal..

The reason for the long failed negotiation is even more mysterious, actually scandalous if it happened in any other foreign country,

Because the GOI has will fully failed to conclude or scrap the deal before the finishing of MMRCA negotiations , frittering away the crucial pressure point.

What took so many years to arrive at the scrapping of negotiations should merit a separate investigation.

Found this information on bharat-rakshak By Mr Shiv . stating that scientist have developed single crystal blades for the kaveri engine. As to the performance of this blades, is not yet know

 

[halloweene]

In a very recent issue of Air&Cosmos dealing with aeroindia, it was stated that negociations failure had been denied by DRDO and that in fact, Snema may be involved in the dev of a 10T class for AMCA.

Would be really good news if true. No point starting all over again through endless tenders.

If Reputed Air & Cosmos is true, Then who is spreading disinformation here ?

 

[Kunal Biswas]

I was about to post these Photos, But Abhi was fast, Anyways more info on Indian developed Single Crystal Blades :

The image below shows the development of tech (in SDREland) from plain casting (labelled equaxed), to "dirtectionally solidified" to single crystal.

The Blades

For single crystal blades to have a hollow honeycomb interior, a ceramic core is used around which the crystals are grown. The core is leached off later. The image below shows ceramic cores with the hollow part of a blade visible.

Here is a fully formed blade - the extra spiral bits needed for manufacture will be removed for finishing the blade.

From the HAL stall - a single crystal blade used in Al 31

Could just be business blind bet game, overhyped by media.

R Sundar , CEO, Aerospace Engineers in a Interview with AeroMag magazine about Kaveri Engine.

Q:What's the latest on the Kaveri engine? GTRE's association with LCA Tejas programme?

A :Kaveri engine prototype was integrated with IL-76 aircraft at Gromov Flight Research Institute (GFRI), Russia and flight tests have been successfully carried out. Issues required to be addressed have been identified and are being addressed and it is planned to commence flight trials for technology demonstration of Kaveri engine with LCA Tejas Mk-I in about three years
time.


GTRE has so far developed 9 prototypes of Kaveri engines and 4 prototypes of Kabini (Core) engines. The engines have run cumulatively for over 2200 hours at ground and altitude conditions for various requirements including performance, operability, endurance, environmental etc. Further endurance testing is under progress at GTRE. Two major milestones
achieved viz. successful completion of Official Altitude Testing (OAT) and completion of first block of flights of Kaveri engine in Flying Test Bed (FTB) have demonstrated the technological capability and maturing of the indigenous efforts.

Further in the magazine It is mentioned that.

LCA will be tested for Angle of Attack more than 22 and maneuvering greater than 6 g.

Press Information Bureau English Releases

The engine has been tested to its potential of 12 MW at ISA SL 35°C condition which is the requirement of Indian Navy for propelling the SNF (Rajput) class of ships. This engine has been demonstrated to the Prime Minister Dr Manmohan Singh and others including the Scientific Advisor to Raksha Mantri Shri M. Natarajan, Vice Admiral B.S.Randhawa, Dr. D.Banerjee, CC (R&D).

With this development, India will become self-reliant in the technology of gas turbines for ship propulsion. This will put India in the elite club of Marine Gas Turbine designers e.g., USA, Russia, UK and Ukraine.

domain-b.com : Breakthrough for GTRE scientists – develop marine version of the Kaveri engine

Bangalore-based Gas Turbine Research Establishment, part of the chain of laboratories operating under the Defence Research and Development Organisation (DRDO), has achieved a significant breakthrough by developing a modified marine version of the Kaveri engine, which it has been developing for the country's Tejas Light Combat Aircraft (LCA) programme.

The marine version is a spin-off, which is capable of generating shaft power for Indian naval ships. Using the Kaveri engine core, GTRE scientists have added low pressure compressor and turbine as a gas generator and designed a free power turbine to generate shaft power.
