There will be no PV4!

 

[SATISH]

I heard PV 4 was supposed to be the naval prototype. So i guess we will have to wait till the new engine is selected.

Thanks , Nitesh for posting such a nice video footage of our LCA project and description by a Foreign Channel and from Western perspective. I think this was from National Geographic Series, enjoyed that one very much.

Regards

Its more than a year since newest LCA joined test program. Can only hope "Very Soon" will atleast be soon. Nevertheless its good to hear something good.

seems PV-5 has finished EGR! next LSTT then HSTT and then airborne! may be in a month. PV-5 looks splendid in photos!

IAF rejects French offer on engine for Tejas

‘Kaveri’ under development at the GTRE for 20 years

Snecma offer did not meet IAF requirements


--------------------------------------------------------------------------------
BANGALORE: It’s final: the indigenous Kaveri aero engine, under development at the Gas Turbine Research Establishment (GTRE) for 20 years with the specific objective of powering the Light Combat Aircraft (LCA) Tejas, will now not fulfil that task.

The LCA will not be operationalised with the Kaveri, since GTRE will not be able to satisfy the Indian Air Force’s requirement for a low altitude, high speed engine with a thrust of at least 90 kilo Newton (kN) within the extended timeframe, weight or volume.

GTRE officials told The Hindu that they hoped a Kaveri engine co-developed by the GTRE and the French aero engine house Snecma could at least become, in the distant future, the power for the Medium Combat Aircraft (MCA) that is still to be designed. “The IAF agrees that the MCA should be designed around a 90 kN thrust Snecma-GTRE Kaveri engine. The Kaveri could be tested on the LCA, but the aircraft won’t be operationalised.”

Conditions not met


The final blow for the Kaveri engine project, which was launched in 1989 as “the engine for the LCA,” and which has cost the exchequer over Rs. 2,000 crore in development, comes after the IAF rejected the offer from Snecma to co-develop the Kaveri along with the GTRE.

In 2005, after GTRE indicated that it would not be able to develop the core technology (hot end parts) for the Kaveri on its own, help was sought: France’s Snecma and Russia’s NPO Saturn made offers to collaborate with the GTRE, the former being pre-selected as the technical partner.

The IAF’s rejection of the French offer comes after a committee, headed by Air Vice-Marshal M. Matheswaran, pointed out that the Snecma offer did not meet the Air Force’s performance (air staff) requirements, did not give the GTRE the core engine technology it was looking for, and did not help eliminate deficiencies in the Kaveri’s design.

“Assimilate” technology


Both Snecma and the GTRE contested the IAF’s stand, saying that the relevant design technology would, in stages, be assimilated to the Indian defence laboratories.

According to Snecma’s chairman and chief executive officer Philippe Petitcolin, his company could pass on the design and manufacturing technology to Indian entities as soon as it “could assimilate it.” Mr. Petitcolin told The Hindu that collaboration could save the GTRE at least 20 years in developing an aero engine.

The IAF committee, which also has members from other key constituents of the LCA programme, suggested restructuring of the GTRE, with research and development being made the area of focus. “GTRE had unrealistically promised to make the Kaveri operational in seven years,” an IAF official said.

bad bad news, i was hoping that one day we could power our LCA with our own engine. So is't a virtual end for kaveri?

 

[Sridhar]

It may power our future ships , trainers and may be cruise missiles ...

Cruise missiles?? ok no one puts a after burning turbojet into a cruise missiles, ships, tanks and trainers no problems but cruise missiles, no way. I am glad snecma lost, they suck. Its either Eurojet or GE for the LCA mk-2. I think we simply need to allocate more money for the Kaveri and spend time perfecting it ourselves, besides there is no rush, as long as Kaveri is ready by the time an engine is needed for the MCA. Obviously we need to get an engine with 100Kn in dry thrust and 130 Kn in wet thrust per engine for the MCA which is expected to weigh around 19 to 20 tons. One of these engines will be gr8 for the LCA which will be able to supercruise well over mach 1.4 with a full load with such an engine.

Sorry my bad ,, it should be UAVs

i dont think we need after burning version for uavs. a simple dry thrust engine is good enough.

Yes a scaled nown , I haven't said it should be a after burning one.

 

[John]

The engine is ideal for small ships, missile cruisers etc, will give excellent speed. An armed UAV based on the LCA-mk-1 would be gr8, no cockpit, more room for more sensors and ability fire A2A missiles, A2G missiles and PGMs. give it the Kaveri, pretty much could be the best UAV on the planet.

This is from the website mate and its official.
http://www.lca-tejas.org/avionics.html

Mission Computer (MC): MC performs the central processing functions apart from performing as Bus Controller and is the central core of the Avionics system. The hardware architecture is based on a dual 80386 based computer with dual port RAM for interprocessor communication. There are three dual redundant communication channels meeting with MIL-STD-1553B data bus specifications. The hardware unit development was done by ASIEO, Bangalore and software design & development by ADA.

p2p! MC with 80386? old news! ! it has most modern MC(OAC)!

I did not understand with the last part.

If you mean to say new processors are being used. We know it. But, we don't know which one. The nearest speculation comes to IBMs PowerPC 400 series.

The 80386 was for dark's information.:113:
