Can you tell us what do we lack?

Going through other threads and pdfs
I understood that first thing these aren't the only critical things there are others which as usual they won't share
Secondly our desired numbers can't be achieved not bcoz absence of basic hot section components but their metallurgy which will achieve the desired numbers that's why we are constantly working on improving the metallurgy of these components and getting new versions of those
It will take time

My doubt I can we learn something regarding American material science through the teaching in machining and coating

Yes, HAL can learn a lots new things from F414 deal, but
<Which Gov Agency responsible for R&D&D of TF engine ??
Is that particular .org part of the deal ??>
it is only good for making the same thing again & again
Good news is, current gov is very serious about LCA pgrm, and need next term for fast tracking this pgrm

From my understanding, we are getting TOT for maintenance and limited manufacture tech. No tech for production from raw materials, mostly unfinished parts shipped from US to be finished here.

Why didn't the Russians provided us this or our govt hasn't done any recruitment to hire experts in this field especially indian Americans who are have experience in core engine tech,yes it requires more funding and doent fetch votes for political party.Why don't we have the 1000 talent program like chinese had to recruit non resident indians or even mixed indians who are working in usa and europe.

HAL Hands Over the 50th Raw Material Phase Engine of Su-30MKI to IAF

“The AL31FP engine powers Su30 MKI and is manufactured from raw material stage. All the components, including heavy forgings are manufactured at HAL”, said CMD, HAL, T. Suvarna Raju. He handed over the documents related to the 50th Raw Material Phase Engine of Su-30MKI to Air Marshal S.B. Deo, VCAS.

"In the last 50 years, we have manufactured 1574 engines and overhauled 7417 engines. We have achieved a turnover of around Rs 1579 core during the financial year 2013-14,"

If this is done then why do we struggle to make drone engines and going to the next step is there a funding issue.

IPR
Simply consider Chinese struggle in developing TF engine
HAL is not responsible for R&D of engines for fixed wing, but in future they will, for CATS

At first 100% ToT which we knew that it would be assembly or manufacturing or maintainance not of the hot core section nor complete
Engine now 80% by value with no clarity
But these cnbc report indicates atmost the 80% tech transferred is regarding maintainance assembly and spares
So it's okay type of deal considering America

It's a really good deal. Mind you this is not a deal for the co-development of a 110kn engine. Even then we are getting significant transfer of technology. Even if we don't get an IPR this goes a long way in ensuring good availability rates and sanction-proofing.
In fact, I doubt either France or UK would have shared 100% tech. Safran was insisting on using the M88 core and if I remember correctly RR's offer was based around its 6th gen engine.

 

[rambogandhi]

Will this 80 percent make it itar free or just like those engine plants in turkey and korea by usa.Usa never sells any military equipment they just lease it one sanction and those will be gone.

I doubt even 100% will do that, we won't be able to export them freely without IP rights.

It's just parts of less technically critical or mostly developed by us being offered to be made
And note that nothing is from raw material stage although even if it would have been then also those so called 80% parts are not that critical
Coming to which particular field are the giving ToT is it manufacturing tech or assembly tech or actual engine tech
As far as I think it's a mix of field being offered but overall not major development it can give us apart from soem learning about their material science
It's not 110kn deal which may may have some significant tech transfer

I think this will help us in sanction proofing. And it makes sense, Americans know Indians distrust them seems to me like a trust-building measure.

India-US deal on jet engines to pave the way for 80% tech transfer by value

CNBC-TV18 has learnt that the deal for co-production has been approved by the highest political levels in India and the US and will be formally announced during the state visit of Prime Minister Narendra Modi.
India and the US are all set to seal a deal for the co-production of fighter jet engines. "The deal, which will be signed between General Electric and Hindustan Aeronautics Limited (HAL), will entail 80 percent transfer of jet engine technology by value," said a source requesting anonymity.

CNBC-TV18 has learnt that the deal for co-production has been approved by the highest political levels in India and the US and will be formally announced during the state visit of Prime Minister Narendra Modi.

According to reports, this is likely to be a multi-billion dollar deal. Both sides are now in final negotiations on payment mechanisms, procurement of machinery and tech transfer modalities.


Sources said the US has not shared engine technology with any country to this extent. "This level of technology transfer has not been given by the US, the UK and France to any country," said a source privy to deliberations on the deal.

India and HAL will get technology for the following aspects of GE jet engines:

> Special coating for erosion and corrosion
> Repair technology for turbine
> Compression disc and blades
> Coating and machining of single crystal turbine blades
> Machining & coating of hot end parts
> Complete tech transfer for blisk machining
> Machining of powder metallurgy
> Polymer matrix composite
> Laser drilling for combustion
> Bottle boring of shafts

The process of collaboration on jet engine production will begin after the signing of the deal between GE and HAL. The technology transfer is likely to happen in phases and by the end of three years, 80 percent of the value added to the engine will happen in India.

In the tweet I linked News18 is reporting that exports are on the cards.

Exports with permission from the US. We can't do it they block it.

Please list out any prospective countries (such as those which are considering Tejas now and follow-ons) where you think they will block us.

US provide India technology for single crystal turbine blades used in jet engines.
