Them having cutting edge SiCf based CMCs and EBCs is sorta hard to believe. But if they have, that would be a massive achievement. Or are these roadmaps rather than anything at even TRL 2-3 levels?

Prasad

uhh there's no association with sss

maitya,
the sx blades are from dmrl.

Prasad

Maitya Given that both rr&Safran are ahead of us in tech capability, what 'co-development' will actually happen and how much will we absorb from them if they develop the core and we do the lp and ab sections? Foreign oems developed new alloy compositions for new engines and engine related improv...

Prasad

Right, Afterburner should have been relatively easier than the TF core - however the expectation/specification is over the top - it's 60% thrust augmentation but with a mass-factor of 1.1 . Most TFs aim for 50%, which is what K9 also achieved - but 60% up-thrusting is where M88-2/EJ200/F414 levels,...

Mk2 happened because the Indian NAVY had a vision for a better LCA. IAF just jumped on that bandwagon and ran with it. Mk2 is a single engined fighter and was supposed to be a quicker solution to overcome Mk1's shortcomings. But given the way things happen in this country, the quick solution has tak...

Prasad

Do people not realise that the Mk2 is just a modern M2k? And that the air force drove requirements from the Mk1 to the Mk2 over the 2009-14 period when the current configuration was chosen? Come on, just look at the specs!

Kaveri engine approved for inflight testing: A breakthrough in Indian aerospace ...

Prasad

If Kaveri generates more power than Rafale's M88, why would that be an issue? Kaveri isn't certified. Only the dry kaveri is considered a ready thing. And even then, GTRE has to put the entire engine including the afterburner on a fighter, fly it extensively. Then, I'm sure there will be things the...

Prasad

I still can't understand why TEDBF was not based on Kaveri. The engine could have been certified by the time of first flight or there about. And a dual engine fighter would have been a very safe option. More than LCA, TEDBF was a bigger backstabbing to the desi engine. Because Navy won't take anyth...

With the GCAP program firming up an alliance with Japan and Saudis as a possible funding backstop & customer to provide scale, it looks like RR might not be in as dire straits as they appeared to be even 3 years back.

5 tons of fuel is roughly just over 5000 litres of fuel. Could well top up a flight of 6 aircraft onwards or on their return leg.

Pratyushji, as far as the Super Su-30MKI upgrade program is concerned, for IAF, I think the AL-41 boat has long sailed, and only Saturn AL-51F/Izdeliye-30, would be able to rekindle that interest. After all, it was not for nothing, IAF was insistent on some kind of participation to the Izdeliya-30 ...

Speculation about Naval Tejas induction? Purely based on a recent comment by the ADA chief Dr Jitendra Yadav - apparently, 1 sq to be inducted, on primarily a Trainer role - will help smooth out production risks of TEDBF and will also increase the sortie rate of the MiG-29K platforms.

... Which in turn means, 1) In the Turbine complex - 4th Gen SC based HPT, better HPT blade-cooling architecture, better TBC, maybe 4th Gen DS Vanes ( SC ones would be prohibitively costly ), PM turbine discs etc Any rough estimate on the cost difference between DS & SC for a given component?

Prasad

We might end up buying 36 more Rafales and however many Navy manages to convince the PMO to buy. If that is another 24-36, it'll adding up to 70 or so a/c. Perhaps that would set the ball rolling on making it here. But with no future prospects, especially if TEDBF is finally sanctioned and starts pr...

We need more diesel-electrics and the nuclear ones to prowl further out and tail PLAN fleets. Our current and near future sub force levels are nowhere near enough for what the PLAN and PN can throw at us in the entire IOR.

What reform? The first point in the agenda itself is to remove drdo chief from secretary r&d position and appoint a babu instead.

Maitya,

High hardness cores are a done deal. I think it was even stated so in some tech focus IIRC.

Prasad

Even in the CMCs we don't have the tech to manufacture certain fibres. And our research into gamma TiAl is still not where we would want. So replacing Ni alloys in the core with these alloys, CMCs in non rotating parts (theyve done tons of research into umra high temperature composites. where are th...

More outreach was his aim and I agree with him. Somnath's answer was that all outreach currently is done by ISRO personnel of their own volition. That is not acceptable at all in this day and age.

GTRE wants to test the Kaveri with afterburner on the Tejas to generate data. Has been asking for it for a few years now. Not the dry version.

Not just that but how much can be extracted from the 414 over the lifetime of the MK2& TEDBF? DRDO wants F135-level engine parameters ( that you'd listed in an earlier post) in a smaller form factor with corresponding thrust levels, nominally 110kN. Even if we get an engine with all these techs ...

No he quoted the tweet. All this is from a couple of chaps in the US IBC. Right until the end, the authors never say there is work going on to create exemptions in itar or capability development assistance in anything bigger than startups who in the Indian context are smaller players for now.
