If they can get the underpowered version into an LCA as a test they can iterate it to the correct powered version. That is how technology is developed. If they take this seriously, I believe they will have it within 5 years.

Atleast things will be started.

Indeed,
Once you have an indian engine that works, you will be ready to improve it small step by small step.
a real ait test bed will give you much more datas that a ground one.
It will take time, but the goal is on the horizon.

Kaveri in house
( the version Godrej I'd making that will go into ghatak will have make max sustained dry thrust of 48kn)

Max dry thrust-52kn.


Max wet thrust-81kn.

F404-"IN20" engine, used in the Tejas

Max Dry Thrust: ~53.9 kN ( 3.6% more than Kaveri inhouse)

Max Afterburning (Wet) Thrust: ~85 kN( 4.71% more than Kaveri in house).


F404 in20 ( with after burner)- 1180kg.
Last know weight of Kaveri( with after burner)- aproxc 1180kg.
So almost same weight.
But if we go by twr of 7.8 in booklet weight of Kaveri comes down to :- 1059kg( with after burner), which Is 10.26 percent lighter than f404 in20.



f404 in20 is barely enough for tejas, meaning tejas is slightly above being underpowered with this engine.
It will be slightly underpowered with Kaveri, if one with inhouse test no. Is fitted.

Godrej is making a weaker afterburner for thrust upto 75kn as jets use dry thrust most of the time, and it's for testing purpose.

F-404 isn't flat rated , Kaveri is. Consider dry thrust of Kaveri as 60 KN at same parameters as for ratings given for F-404 & wet thrust at 90 KN.

If that's true then why isn't thus being integrated in Tejas at fast pace for testing?
Specially after delay of f404 for more than a year?
Kaveri has completed ground and aerial test with ill76 succesfully

Because it's not been flight tested except for the FTB & from what I understand they're planning on testing only the Dry Version of the KDE aboard the LCA as of the present meaning in the next 2-3 years.

If those tests turn out to be successful , they'd mate the AFB onto it & carry out further tests. Can't vouch for the veracity of this news as it doesn't make sense given the dry version of the KDE is going on board the Ghatak which should also fly in 3-4 years from now.

Means one more modi term required, i dont think other party will support this.

I believe the initial Flight Tests of the KDE will be on board the LCA. If the basic parameters are satisfied 2 developments are lined up - the first being the KDE goes on board the Ghatak where it will be certified for FOC of the entire system & the second development (which is still not clear ) comprises of either mating the AFB with the existing KDE ( Dry Thrust 47 KN & Wet Thrust 73 KN) & testing it on board the LCA or sanctioning of a new program the Flat Rated Kaveri 2.0 expected to give an output of 54 KN Dry Thrust & 81 KN Wet Thrust meaning 60 KN Dry Thrust & 90 KN Wet Thrust at ISA.

It could also be that in case of the second development the 73 KN KDE version is tested followed by a new project to construct the Flat Rated Kaveri / KED 2.0 with 81 KN Wet Thrust.

Please note that the above information is my inference NOT from any single source but which comes from multiple sources on SM . Take it with a pinch of salt.

Any idea how much of this is for kaveri jet engine dev ? Does it continue to be peanuts ? Why no patrakar asks these Qs ? I thought Saurav Jha and his team would cover such things and ask tough Qs, but I guess they're short of manpower, rest are busy jerking off to cricket, sullawood and politics 24x7. Maybe we should form a media team ourselves here at DFB and go ask these Qs We might get jailed by herr genrols, but hey, desha seva, janani janmabhoomishcha and all that...

Bruh, you are going way into Bhavishyat kaal, first let maulana release massive funds for jet engine dev and allow them to acquire FTB. Orders are later.

BTW I firmly believe if we had an FTB, by now we would have ironed out most of the problems in kaveri. Its a huge statement on incompetence of MoD GoI babus and GTRE babus that the former did not provide funds to acquire the same and the latter failed to convince them to release funds for the same (or maybe GTRE babua wanted to continue this mnrega kaveri gravy train as a life long project).

Also can anyone tell me why a CATS warrior can't be modified to become an unmanned FTB for kaveri ? That way you can avoid the requirement for a manned twin engine jet as an FTB.

@Ayan Barat &/or @Bhartiya Sainik are the best people to answer this question. They post on so many topics, one would have thought these original thinkers would have thought up something like this .

But it had to be you . Jaise daane daane par likha hain khaane wale ka naam theek usi tarah khayal khayal par likha hain sochne wale ka naam.

BTW it's a very novel suggestion. I wish I could've thought of it. Feeling jealous.

Doesn't flat rated mean it will be 54/81 at ISA too ?
