Kaveri Engine

[amit6371]

I am sure you did not mean the way it comes off....they are still valid but the interactions of other parameters in real world need to be factored in. Errors and losses and few other aspects need to be understood and remedied.

Yes, you are absolutely right. However, the modified equations are just used for initial rough calculations after that, FEA, CFD, and, most important, i.e., experiment data get the first place.

Let me take an example that we do not consider in theoretical calculations. A big portion of the compressed air is extracted from various stages to cool the combustor chamber and turbine blades. This extraction of compressed air heavily affected the efficiency and size of the engine(compressor).

I can share what I know, If you guys are really interested in the technical aspects of Gas turbines.

Happy Diwali

Who "chairs" GTRE and are people aware of what sounds like your fair criticisms of it? What is needed to make the change? what politician needs to be made aware of this?

Happy Diwali bro.

Yes, share more please

None other than mudi ji himself.....all others are useless

Watch recent video of alpha defence .

Watch recent video of alpha defence .

some RQ4 GLobal hawk like HALE program might resurrect enormous funding for GTRE.. It would be beautiful.

Kaveri achieved sustained thrust of 73KN and govt agreed to integrate Kaveri to a Tejas prototype

Nope, that is the suggestion from alpha defence to our gov.

FIrst with LCA t hen with Tedbf's non-navy variant should have some unit as testbed for Kaveri.

watch it again, he said that govt agreed to transfer a Tejas to GTRE to integrate the engine

where.. timestamp 3:50 is a suggestion.

Kaveri achieved sustained thrust of 73KN and govt agreed to integrate Kaveri to a Tejas prototype

Wait now I am confused
Wasn't that kaveri meant for ghatak ucav sent to Russia
I mean required thrust of 50 kn
Now from where did the original variant of kaveri was sent and tested for 73 kn thrust
Pls explain
If it has achieved 73kn in non after burning stage does it mean it can achieve 50 kn without any modification

73 with Afterburner. 50 something with dry..

For comparison RQ4 GLobal hawk with 14000 km range has < 40kN engine.. but has 30% less weight.

We can remove some HP stages for weight reduction. DOn't know the trade off with the thrust.

I didn't see the video did he say 73 kn with after burner

If it had 73 without AB , we wouldn't have been dealing with G.E. anymore , let alone for Tejas MK2 engine.

But requirement for mk1 and mk1a is 83 kn+ right
How could it fulfill it
What's the purpose of integrating it

no one is integrating anywhere yet.
with 50 Dry and 73 wet. Its underpowered for Mk1 and 2 both.

Only twin engine project can create a good T/W ratio jet similar to Rafale / tedbf.

Kaveri won't be powering Tejas.But they are planning to integrate it to a Tejas prototype to flight test in Limited envelope

in Video.. alpha defence is suggesting the govt for utilisation in LCA Mk1 prototype for the time being.
Other than that you got some source ?

Alpha directly spoke to GTRE chief...this is the biggest source. I'm waiting for update from DDR. Our own @jik60 got update that Dry Version is currently under flight testing in Russia

but it is Alpha's suggestion. He didnt say that GTRE chief told him about such future plans.

Maybe GTRE want such path to happen , so they put words via Alpha;s mouth.
