If Kaveri doesn't become ready in time, we will have to import the power plant for the AMCA from the US, UK or France. I am sure that out of the three countries I mentioned, we will be using American GE series engines to power the initial batches of AMCA. Subsequent Batches will utilise Kaveri or a engine made through a JV with either GE, Safran or Rolls Royce but directly imported though. For now, we need to play our cards well if we want an engine for AMCA, it's not an easy task to maintain a balanced geopolitical stand between the US and Russia, few countries on the planet have the privilege to achieve such a feat, fingers crossed that Kaveri eventually succeeds because jet engine technology=>crucial.
I would like to give an quite controversial suggestion.
There is a saying.
If something is very important and necessary.Then to achieve the objective - 'Beg, Borrow or Steal'
Now I am not saying that we do not have the brains to achieve the objective.But sometimes short cuts have to be resorted to to save time.
Set up an exclusive fund of 100 million US dollars (to start with)to enable R&AW to begin efforts to acquire the crucial hot engine technology of high performance turbofan engines.Use covert techniques to bribe,recruit senior scientists in the top aero engine manufacturing companies.
If it is called stealing technology,so be it.
Nothing new.The USSR I believe gained access to nuclear weapons technology by recruitment of senior US/UK scientists.Espionage operations.
The US got an Soviet pilot to defect with an then high technology Mig 25 plane because it wanted access to its technology.
There would have been many many incidents of the US and the then Soviet Union stealing each others technology secrets.It is a fact of international relations.
Morally wrong may be.
Even the pigs next door Pakistan stole gas centrifuge technology for enrichment of uranium from companies/organisations in Europe.The infamous A.Q.Khan network.
If detected, bilateral ties may get affected.I guess an bearable cost if the objective is achieved.
Would it be an impossible task to successfully infiltrate the top turbofan manufacturing companies even though firewalls would have been setup by these organisations.
The alternative is to follow the Chinese.Invest billions of US dollars and set up multiple teams to solve each part of the Turbofan Engine puzzle.
Involve the private sector heavily.Continue heavy funding till we succeed.
