Kaveri Engine or some other? How far is India from indigenous fighter jet engine, AK Bharti answers

Kailash

That certainly looks like a A/B integrated Kaveri - not sure if this is KDE+A/B or a baseline K9+brand new A/B (maybe from Brahmos Aerospace). But either way, certainly a +ve development ... Should be the KDE. It is the most natural evolution sir. Technologically, manufacturing wise and level of te...

Flown on an indigenous platform.. so Kaveri will go straight on to Tejas mk1/2. The confidence should be high, to skip a twin engine platform like a mig29 and directly put it on a single engine. Hoping this happens within the next 2-3 years

Exactly Maitya ji. The Japanese engine is an orphan, which has consumed a lot of funds, time etc. Only thing left is for them to monetize it. We will have a workhorse that serves us for the next 2-3 decades. If it will consume more time to derate it to 120-140kn, a powerful single engine fighter in ...

Can we expect anything substantive for Kaveri 2.0, in terms of testing infrastructure, or a KDE+AB flying on a Tejas or a mig29 after PMs passing reference during the independence day speech? KDE never had any fanfare or PR until the testing in Russia was almost completed, and it exceeded the design...

Give the Kaveri program at least half $3.5B and see what happens. Kaveri is so important not only for aircrafts but Ships for Indian Navy. All of the modern ships for Navy currently have GE powerplant - destroyers, frigates, aircraft carriers. A good Kaveri program can lead to ship engines which ar...

Lot of questions about the Japanese engine can it be quickly modified to the dimensions of the F414 how much of testing was done, reliability etc whether we can quickly use it, as is, in a LIFT- hlft42 or su75/f35 type single engine behemoth How are they able to make that work with single stage lpt/...

The nature of air war is changing. Fanne ji, I'm in 100% agreement. Kinetic performance like speed and maneuveability though vital, is not everything in today's war. Speed of fighter design can't catchup with speed of missile or radar development, or speed of EW development. Beauty is it doesn't ha...

Even if Kaveri weight is brought to say under 1100 kg with a 81KN wet thrust, with the flat rating, kaveri is nothing to be scoffed at. What we need is integration, even if it finally leads us only to a less powerful export variant of Tejas. A slightly heavier, similar thrust Tejas doesn't sound so ...

yt rumour has it that PV-5 and one more lca PV will be used to qualify it. No takeoff without A/B. Either too many milestones have been kept well hidden, or we are still a few years off.

Has the full scale development of Ghatak UCAV been sponsored yet?

We should immediately fly what we have, while trying to improve it. Is the A/B integration done??

Maitya ji, if these companies are so cash strapped, would it not make sense to buy them outright or at least take some strategic stake in in these companies? Another noob question I have is don't we have a combined requirement for over 2000-3000 engines in the next twenty years? Will we not extract ...

Even the japanese have a high altitude engine test facility. We lack creativity when trying to find solutions. This is assuming we did not want to go to any of the western nations.

Really hope we have a few squadrons of the UCAV, just to allow unobstructed manufacturing of kaveri KDE.. if not for anything else, to keep the private players commercially interested on the project.

This is a question to all seniors, why can we not delink a mission mode engine dependent initiative, incubate and fund it irrespective of customer wants?

Basant ji, thought I see the logic in your argument. But I feel research funding/timelines should not be held captive to requirements of services. In other words, engine research should be sustained with a vision for a family of useful engines ranging from turbo-shaft, -prop, -jet , -fan with as muc...

Maitya ji, I don't see the French in your long post defining the short medium long and ultra long term plans. Was this deliberate? Do we not need them in the mix?

So this new fan is part of the 8 engines produced already. Will this additional fan fit within the envisaged dimensions/weight of the afterburning Kaveri?

It is a twin engine jet. My supposition is 230*2*2(replacements over lifetime), could be to the upwards of 900+ engines. If that's not the case we'll probably be getting the IPR, paying a one time royalty on future production as well..
