Kaveri Engine

[ersakthivel]

Thanks. You are right, that's the reason soldiers break their steps on bridges.
Since nobody is talking about any spooling problem I guess there is none like in
chinese engines.

It is going for a high altitude flight trials means no debilitating problem is there. but still it is a generation behind it's western peers in so many parameters that needs to be worked on for a decade at least.But it validates most of the theory calculation and it's practical application, which is not so insignificant mile stone.

You are correct not civilian version, RD-93 used on JF-17 fighter.

License Mfg. of 99 GE-414 as per Wiki.

I said GE-404? I meant GE-414.

Kaveri we all hope for the best, that problems will be solved.

Sir,
I dont refer wiki but the GE-F 414 is NOT going to be license produced in India, if the US could give the tech to produce the product under license, they would have to give the technology first...which is what we need...get the meaning of license production clear.

 

[Dinesh_Kumar]

Yes, I see your point of view.

Using same approach as AL-31 engine, which we have been making under license from raw material stage, can we build 90-100 KN engine?

After all, 90-100 KN is less difficult (probably) to achieve than 123 KN of existing engine, which we make under license from Russia, and that too, from raw material stage.

In case of Al-31FP, AFAIK they are just assembled and not produced from scratch...gurus wud know better....

 

[Kunal Biswas]

RD-93 is a modification not a upgrade of older RD-33 engines from mid 80s, It has to do with the gear box..

===========

We have already archive crystal blade tech, Preciously what we lack is >>

1. Turbine: Increasing the TeT from 1400deg C to 1700deg C regimes, by mastering the 3-4th Gen SCB tech.
2. Compressor ..

There is NO civilian version called RD-93 it is an upgrade of the RD-33

Lastly the problem with the Kaveri is with its compressor and crystal blades,

Russian option,.

======================================

It is licensed produced, Also a little modified..

In case of Al-31FP, AFAIK they are just assembled and not produced from scratch...gurus wud know better....

Dumb question can we use kavari for bombers ? Let say we make supersonic bomber with 4 of these engines for long range missions ?

why we need four or five engines for single bomb...
we already have small turbo engine ....That we use in Nirbhay missile.

Kaveri engine is designed to lift Aircraft

Ever saw something like blackjack kind of aircraft ?

Maybe, we cannot be sure.

Two engines will be enough for the Bomber.. Lot of technology is already there If started Can be done in 5 years. with present day technology and infrastructure.
If stealth is applied we can have medium size long range bomber.

Long range bomber, this would be good start.

 

[sayareakd]

We must get success in Engine, then super cruise engine is next step.

Once we get engine, then we can build almost all types of aircrafts.

 

[dealwithit]

Our aviation in Industry is little boy.. in front of giants like America, Russia, UK, France and Germany.. There aviation industry is best estb and started 50 years head of us.

I think DRDO worked very hard to keep pace with world. And it is getting nearer day by day.. And unlike western countries DRDO is state owned Organization.

our students in Mumbai helped airbus jet engines to reduce noise.. But, this talent choose to travel Abroad for various reasons(money,life)

If will build our final engine in next 3-4 years.

 

[sayareakd]

I think Engine is important and more funds should be spend on this.

We should have three routes to this. 1st local R&D, 2nd buying tech and JV with others and 3rd other means to get tech.

All three are needed to get self sufficent in engine tech, not just for LCA, but for future engines too.

 

[dealwithit]

Long range bomber, this would be good start.

DRDO always goes with LIGHT LIGHT LIGHT... LCA LCH LUH.

can't expect to start Bomber with Long Range. Considering China Stealth is more important..

As for now DRDO just doesn't want build any thing.. It thrives for perfection.

It is not their fault it is operational requirement. Just wait till we go for next generation things.

But for some strange reasons neither IAF or Indian navy have raised any needs for domestically produced bomber or transport aircraft of AWACS or naval reckon aircraft till now.

I am sure the country will need a lot of 4 engined heavy military transport as well as AWACS and bomber platforms in future.

If such requirements are not forthcoming from the services DRDO alone cannot get a government nod for such a program.

May be they are not sure if DRDO can make it, but what is more amazing is the fact that they have never asked for such platform (bombers), except for Navy which wanted long range recon aircraft.

We currently don't have a requirement for a bomber. We can't build any at home for two reasons. One is obviously we can't build one. The second is that even if we build one we won't be able to make the project viable since the numbers ordered will be too less.

The Americans made the C-17 and ordered in the hundreds (224). The Russians are ordering at least 39 IL-476 initially and a follow on order at a later date. You can expect the Chinese to order aircraft in the hundreds as well. We ordered a paltry 10 C-17s.

Anyway, if we ever decide to build a transport aircraft, it won't be DRDO's responsibility. Sense will prevail and the order will go to HAL or even NAL. NAL is working on the R&D to build wide bodied aircraft while HAL will be fresh from the experience with IL-214. DRDO can never even think of making one.
