GTRE GTX 35VS Kaveri

[Anants]

Kaveri is a leaky turbojet right now. The proposal for a VCE is still a proposal.

We are aiming to operationalize the Kaveri first & foremost.

Theoretically, a leaky turbojet can be converted to a VCE. But this would require a big upgrade to the hot section of the engine. VCE would allow the bypass ratio to be increased, with that the TET would also increase. If the hot section of the engine cannot survive a higher TET, VCE would be pointless.

Kaveri prototype 8 (K8)- 1430 kg (equiaxed blades & vanes)
Kaveri prototype 9 (K9)- 1235 kg (DS blades & vanes. This prototype was flight tested in Russia)
upgraded Kaveri prototype 9 (K9)- 1180 kg (new distortion tolerant fan, single crystal blades & vanes, YSZ-LZ TBC, modified gearbox)
Kaveri prototype 8 (K10)- 1100 kg (target weight)

Modification to the design, especially the afterburners. Inclusion of 3D printed parts in cold section of the engine.

Lab scale production. Used for ablative testing so far.

By itself BMGs may not be as effective. But, BMG when sandwiched with CMC can make excellent TBC material.

BMGs are metals except they don't have crystalline atomic matrix. They have an amorphous matrix like glasses. BMGs are incredibly tough, very lightweight & have better high temp creep resistance than CMCs.

CERMET is a subset of CMC.

=============================


The above is a conversation between myself & Gautam Sarkar of Strategic Frontier . He's been following the program for a long time & has done his Masters in metallurgical engineering which means he knows what he's talking about.

Can you ask Gautam to join here?

He's a moderator there . Doubt he'd join. Moreover he was a member of DFI though he rarely posted there.

what is the service life of these chinese engine? if it is 3000 hours plus, then India is cooked.

Ya'll last time heard it was still sub 3k but they don't care about it.

 

[pipebomb]

Which FTB are they going to use for kaveri ?

Ya'll Twin engined ofcourse probably a MKI.

As long as they don't use single engine aircraft all is good. MKIs are precious resources though

The guy's right... That's exactly what we should think like.

Its 4th gen engine. Kaveri is 3/3.5

GTRE Mate you should be looking for 414 replacement also.

Jumping too much ahead is also how they fell first time. We can't skip the steps from F404->F414->75/110 Class.

Lol... 404 and 414 are both same generation engine(4th). Jump is when you are going to next generation like what would you power AMCA MK2 with(Variable Cycle 5th/6th gen). 414 replacement would be reusing 404 tech for 414 size engine. So GTRE should in parallel start developing 414 replacement like now because that will be mainstay of two near future fighters LCA MK2 and AMCA MK1

Do watch.

Trying to understand if this report says the Test Facility, i.e Test Equipment, sensors etc is nearing commissioning or is this just completion of the building that is will at some point in future host such equipment?

Since we haven`t even begun designing this engine, can`t think of why this facility will need to be operational in a hurry unless it is planned to use this facility to test current iterations of Kaveri
