Message #1312 gtre kaveri thread - strat front

It is underway trials technically, the engine will be put on the FTB in September though (for now). The same person reported this as well btw. The interesting thing to note from the two pieces is : "25 hours of testing left" and paraphrasing "some changes were made in the engine". I can't draw the conclusions because I lack the technical knowledge.

Can someone suggest some good books on gas turbines

Japa were progressing pretty nicely with their own jet engine program until, they were told ( threatened) by unkill to stop it

Japan + UK had very similar requirements for a new fighter. It made sense to join forces. Japan expected to spend 40 billion USD on its F3 programme. Why duplicate cost if another country was pursuing a similar objective? 100 F3 were expected to be ordered initially. UK, Italy perhaps 200 Tempest. Massive saving on dev costs and economies of scale on production from a joint UK, Japan, Italy programme, enabling Japan to order far more than 100 fighters.

You engineering major is CS, as far a I can remember.
Wouldn't reading about Gas turbine be counter productive and redundant utilization of your college time?

electrical is my branch but i am also a part of software engineer factory due to situation, rn i have 1.5 months break still left so thought to read about gas turbines a bit more

to grasp basics you may refer to books pertaining to thermodynamics, fluid mechanics and heat transfer

a dedicated subject of Gas Turbine Aero-Thermodynamics may have their own set of specialised books for topics

i remember we had a giant ass 1600 some page wali Engineering Thermodynamics book with a jet engine cutout on its cover when i did my enginiggering, but only some elementary chapters were picked from it for our common Engg Thermodynamics subject in first year of unified studies, but it might not be sufficient for thorough studies I think

That's some weird ass afterburning section from Pratt & Whitney.

Designed to minimise infra red signature of exiting gases.
IR stealth.

Also the model of ngad used here is a render from an artist, not an official design of ngad.

kaveri toh lmao ded ho gya fr fr no cap

KDE dry is gonna happen at maximum

I don't think it's dead, may be used experience in another project.

Remember given after burner project to bhrahmos jv team.

Tbh there are problem with Kaveri's design itself. And even with afterburner and new materials. They won't be able to reach necessary thrust to weight ratio. So, ig they decided to abandon it in favour of a new project. Kaveri became KDE that's it. So technically not dead. Partial success you could say because KDE will power Ghatak.

i still believe that if we pursue the project properly, kaveri can be integrated with the 97 tejas mk1a or atleast 2/3rd ie the last 60 mk1a

but the reason to lmao ded it might be to shift the entire workforce to amca engine development, idk what was the reason to kill it, but i hope we can get the next gen engine in 8-9 years

Tbh most of that news about afterburner, new material, crustal blade, etc. are an internal project. Basically R&D of Kaveri is still alive so they can use the learning experience on next project. The orginal Kaveri is just an internal pet project of DRDO now. All that learning experience will go into new engine.

maybe we should all go on the iah program and spam our doubts like what's the actual timeline of tejas mk2, what is the future of kde and new afterburner coupling, kusha timeline, what is the status of frcv right now, what is happening with indigenous diesel sub, who will design it? project 18?

@4 min in this video, saurav says, kde dry has completed ftb trials in russia

i think giving ghatak to ade was stupidity, you know ade is bs lab, why give it to them?

 

[redpanda]

Are dukh kyun ho rahe? KDE is still there. This is how R&D goes. You should be glad we learnt something from it and it finally became useful for something. Atleast this R&D went into something. Future of KDE is bright because it exceeds thrust requirements. All they have to do is reduce weight.

Yes. Full credit to DRDO & GTRE for keeping the project alive thru internal funding & for incremental development of various technologies not fully realised on the Kaveri respectively after BA in History / Eng Lit ( Hons ) from St Stephens / JNU babooos in MoD / MoF cut off funding.

Ironically this was done in MP's tenure as Raksha Mantri IIRC. Whatever may be the case it was a monumental blunder on par with whatever we did with the Marut project.

dukhi isliye hun kyunki agar hum kaveri par all in bet karte to maybe 41st tejas se hi kaveri aa jata with full 85kn thrust, we have always let the bus leave, we never missed the bus, we as a country are banana republic

and full respect to drdo people and gtre who somehow continued to research on kaveri and turbofans, atleast we had hopes, which meant we believed them, they redesigned almost every part, from turbine entry fan blades to blisks to bypass ducts to new afterburner

again an ignored and forgotten warrior for kde was dmrl, they have the work to work n superalloys and single crystals, they worked on it in really good way, if given proper funding, work could have been accelerated

kaveri was a really good journey, although didnt finish on a high note on how we wanted, but its daughter kde will fulfil the dreams with ghatak

now all i want to see is amca engine on amca mk2 with full mass production by 2035-36

Tbh we did try to revive it with Snecma Collab. But Snecma tried to sell us Chuna in the name of ToT and then it died again after fallout with GTRE. That is why I have a lot of fear with JV engine. Nothing stops such spats from arising again over ToT.

What is the official source which says Aerospace is developing the new Afterburner ?? as of now all these are just rumors, stop hyping things, stop prophecizing

True. As of now only IDRW is reporting the news.

Did a bit of digging & asking around only for this to turn up .

Trust this satisfies the skeptics. After all an AFB without the dry version of the TF sounds suspicious. And if the AFB is being fabricated it follows that it's going to be utilised somewhere. Connect the dots & see if you arrive at any other conclusion.
