On Tejas.

I think the day we all were waiting for since our birth or our parents birth
integration of both indigenous components finally
The day the flight happens, a party should be sponsored by the owners of this forum and other too

I highly doubt the the KDE will go on an tejas. Won't the lack of the AB will cause unnecessary complications in flight characteristics .. and don't fighter require the AB for takeoff ? (ok this is a moot point .. can always have a longer runway)

Kaveri engine undergoing trials in Russia, to power Indian combat UAV

#FundKaveriEngine trend gains traction as India sends its indigenous fighter jet engine for testing in Russia

The Kaveri jet engine project, long delayed yet vital to Indias defence self-reliance, is gaining fresh attention. Developed by DRDOs Gas Turbine Research Establishment, the engine was originally meant for the Tejas fighter jet but faced setbacks. Now, its derivatives are set to power future...

No and no.
Afterburner are only used for short take off/fast take off/ with full payload short takeoff.

Other than that afterburner is used for rapid acceleration and supersonic performance, for general subsonic performance with good payload, only dry thrust Is used.

Must be some timeline 1 or 2 year

Could be given our babu dum, who knows even more delays can arise.

Multiple news & tweets, nobody knows which is correct or wrong.

Money not issue saar, we will fund saar

On Tejas.

Not happening.. Every Modified tejas belongs to IAF and they haven't cleared such endevour. It is proposed but IAF is not interested.

with or without post combustion ?

Dry thrust tests…
Wet thrust stability is still far for GTRE due to turbine inlet deficiencies

IIRC a new fan has been designed. As far as wet thrust is concerned , B rahmos corp has been roped in for redesigning after burner. Issue was flame flickering in Hot section which were seen when they tried to augment wet thrust to 80 kn from 74 kn. When Kaveri was concluded they settled on 74 kn until new after burner is new designed. Lets see when do we after burner version of new Kaveri.

GTRE has basically asked Govt to look for foreign and private partners to look into hot section for stabilising wet thrust as they lack enough expertise, hot section aka turbine inlet.. hence the RFI for RR and Safran

Turbine Inlet Is not equal to HOT section of Turbine Engine

You are quoting out of context.. Those RFI and JV was for 5th gen even 6th gen Engine..

Inflight testing on what platform?

Its was always for hot section, neither Safran or RR is closer in VCT engines aka next gen engines…

Hot section is basically Turbine Inlet section of Jet engine which need to be stable enough to take very high pressure and very high temp(till 1800 to reach 85 KT wet thrust atleast 15 min)

IL-76 Test bed if I am not wrong we are sending Kaveri from more than a decade for same

I’m not concerned about the hot section—I want to see a dry Kaveri engine actually powering a drone. But there’s no mention of what platform it will be tested on.

Then it’s nothing new

 

[Ajatshatru]

These tests of the Kaveri engine on IL-76 testbed have been going on for the last 30 years—there’s nothing new about it.

Subsonic ghatak dont require more than 30 KN thrust as per current specs .. dry Kavery will get closer to 50 KN on peak load if we are successful lets see
