I can only laugh at us forum members who were dreaming about Kaveri flying by 2018 with the help of the french, these French have not done any great help which we were looking for and by spending all the money on expensive Rafales and ignoring Russia we have also pissed off Russia and they may sell SU35 etc in future to Pakistan.
It may be an art but has been developed by Russians, British, French, Americans and recently Chinese. Also, the first 4 developed engines of high standards by 1990 itself.
This is extremely stupid talk. You speak as if you are the know all. No one asked your opinion. It is a fact that HAL makes AL31f from raw materials. Just because you are useless does not mean everyone else is. Your psychopathic mindset may not be willing to accept it but that does not matter. India is not an idiot either. It may have made some technology on its own. Also, China makes AL31F engines themselves which they name as WS10. Russia, apparently gives 1 generation older technology to its close partners
I have been repeatedly telling you to compare France of 1990 with India of 2020. Let us not go into an infinite loop. rance made M88 in 1990 even before supercomputing, internet and advanced softwares were available. Supercomputing started in 1990 and expanded between 1990-2000. Compare that with India of today.
Are you comparing India of today with France of 1990? If not you sound extremely stupid and probably even proven yourself to be one. France made M88 in 1990 and India is making Kaveri today with same standards. The technology has saturated and has not yet grown. The problems with slightly smaller lifespan is insignificant for now.
I never said that experience is wasteful. I am only saying that there is something called "saturation level' beyond which one can't go. That is also the reason why France has not been able to make any better engine than the 1990 made M88. So, stop fooling yourself and everyone else with theory of "infinite growth" over accumulated experience.
So, now you are changing the tack? By the way, certification is not something that requires great technology. It just needs some experience in debugging. WEven without certification, an engine can fly. Certification is just a formal approval of reliability upto certain standards. It does not constitute ToT in any way.
So, giving credit to France for ToT is absurd when all they are doing is certifying
More than 85% of the engine is made in India, and it will rise some more. Only some very highly secretive materials are imported.
The only reason the French are willing to give us engine technology is because we are extending the Rafale carrot to them.
GTRE is waiting for funds. The govt hasn't yet released it.
I don't know where you 85% comes from or 15% secretive parts come from. HAL openly boasts of makinge verything from nut and bolts to disks and blades. Al31F is older generation engine and has TET of 1700K. With addition of cooling vanes, the TET can come to 1750K even without having 2nd or 3rd generation SCB which requires rhenium.
The 15% you are talking may be the raw material cost which is imported from Russia as part of the contract as "license fee". It is only raw material and not processed components and only serve as a form of license fee payment to Russia rather than capability gap. The raw material can be sourced from India itself or from other countries like Canada, Australia or Africa too and there won't be any difference.
So, if we exclude the raw material cost, the entire manufacturing is done inhouse. Raw material is not HAL's work (HAL is not a mining company) and hence not to be included in manufacturing ability
I first said Certification is important. Its not just documentations alone. You need a separate test system to certify that this product is good. And that test system has a series of do's and dont's and has its own laws and criterion to satisfy. Oh God. !!
And second, I do not know if France "have" helped us or not. But I do support France helping us. Cos their engines of 1990 are flying in their aircrafts and our dont. Now they have experience in building and maintaining engines. They are themselves looking to replace M88 and build next gen engines. Now is our time to do joint R&D to develop an better engine for both of us. If the French sees potential in Kaveri and use it to adopt it themselves for future requirements it will be win win for both.
However I am not sure if Safran had done any work on Kaveri. But it would be good if they do. Bye.
they were planning to convert this engine into a general purpose gas turbine for use in electricity power plants. what happened?
Not related to Kaveri. We are working with GE for power plants.
BHEL tests new gas turbine
For alternate uses of Kaveri, our first objective is navy ships. We have to scale up or design a brand new engine from there.
Once the Kaveri project is done and dusted , the potential spin offs are enormous. From ships to powerplants to rail engines , etc .
Not so easy.
Each steel manufacturer has some specific items, specially in this high grades. It's possible you can't find a perfect substitute, and what about the warranty.
For exemple, does india produce HLE 80 ? It's a 30 years old product.... (maybe it's the case. I really don't know).
Raw materials are not processed materials. They are quite easy to make. Even though India may not have the resources to make in industrial scale of million tonnes a year, defence related items can have a few thousand tonnes a year production. The definition of raw material is that the technology used is relatively simple to get to that form.
A single crystal blade, before machining, is a raw material. But all but easy to mimic.
You are not understanding the difference between intermediate goods and raw material. SC block is an intermediate good which is obtained after processing (alloying, heat treating) of raw materials
France's Safran Aircraft Engines, which carried out a technical audit on @DRDO_India's Kaveri jet engine development program, has stated in a report that the engine had attained sufficient maturity to be integrated with an aircraft for limited envelope flight testing.
S
so when we can expect this engine to be integrated with aircrafts? No timeline
a few years.S

From limited flight testing to full combat ready it takes time. Let's say 3 years.
