DRDO SHOWING OF THEIR K-10 TO MODi ji?

I hope modi ji understand the depth of jet engine development and release required funds.

An entire lab needs to be dedicated only for engine development.

GTRE is that lab.

Nirbhay, MWF, Uttam AESA, AMCA, Ghatak UCAV, K10 Kaveri
Interesting choice of exhibits.

DRDO needs additional funds for these projects, maybe that's why these all were displayed.

I think India is stuck in vicious circle. When you do not have best of Metallurgy technology, your design shall always be conservative (like Russian do) . If you design an ambitious engine (Such as only 5 stage compression in case of Kaveri), and can not come up with required blade and other metallurgy technologies, your engine will remain inefficient (As it happened in the case of Kaveri.) As we had to bridge a huge gap in technology, a Herculaneum effort was required. we fell short on budget and efforts. Russia was ready to help but we found those technologies bellow par with best. I believe that the only way left is to work hard and allocate a big budget to make it happen and simultaneously develop futuristic technologies such as parts containing ceramics, composite fans etc.
Recently, we have made a good progress in thermal coating and single crystal blade technology. This will require change in design as well to fully exploit these technologies. We must design an ambitious engine and work simultaneously to get the technologies by the time they are required.

GTRE is filled with incompetent govt chaps and kamchors who believe in 'working' 11 to 4 shifts with God knows how many tea breaks....
So much for this 'lab'.

How does one know that it is K-10?

 

[Assassin 2.0]

How does one know that it is K-10?

Because development of old engine is technically over and development of new prototype with 110 KN thrust is started and it is called K-10. And this one is having different fan.

The other thing what went wrong according to me is that we designed Kaveri with very low bypass ratio which requires very high core efficiency. In that time, there was no such engine with such highly ambitious design. Had we taken some practical route, things would have been different.

yeah kaveri has lowest bypass ratio in it class
its essentially turbojet with useless fans which doesnt add any extra thrust except weight.

Such as only 5 stage compression in case of Kaveri),

Previous prototype of kaveri had 5 stages. But after testing it was turned into 6 stages. ( which is a standard nowadays only British EJ-2000 is a 5 stage engine.)
If we keep on adding stages weight of engine also increases with that.

Only solution to the problem is developing better metallurgy capabilities.

Better metallurgy as well as better design. Metallurgy becomes more important in hot area.

Actually if GTRE would not have been there, our Missile program itself would not have taken place. There would have been no Shakti engine. There would have been 0% of indigenous components in Marine gas section.
One aspect which we all just ignore is that these are labs and they are not into manufacturing part. GTRE is responsible for sub components designing of almost all the engine parts because of which we are being able to increase indigenous components in those engines.

Infact, it is a fashion of many guys here to curse DRDO and other government organization. They are slow because of many procedural aspects but they have delivered. What ever respectable position we hold today is because of their efforts. These are wonderful organizations. We should think about how to strengthen them.

Foul mouthing DRDO, HAL and others is mostly Arms Merchants inspired topics of discussion. Most of the anti Indian topics in the media or discussions in forum begins with Arms Merchants starting the discussion. Then it becomes an open season for young and brash to continue unhealthy discussion. Later the the so called analysts pick up the discussion and continue with articles, mostly unhealthy and each is claiming insider sources. In someways the arms merchants are highly successful in their approach.

True. They have their typical inefficiencies but whatever they have delivered in a small budget is mind boggling. In that tiny budget, they have either have put as at par or even ahead of many developed nations. They have delivered excellently in the area of missile technology. They have delivered reasonably well in radars and fighter plane technologies and other areas. In many futuristic technologies, we are far ahead of most of the so called developed nations.

I'd like to know about a few of them..

The highest service from GTRE now will be providing a 40+KN engine to stop 110 jaguars from going wasted.

HAL HTFE-25 seems to be perfect fit for Jaguar.
