I am not good at speculating, being away from the Aerospace industry for close to a decade now, I am quite cut off from general development and industry mindset.
India has a price point advantage for general engineering product development, but knowing US engineering industry, critical component, even as trivial as a profile for a screw compressor is guarded with utmost priority to such extent that even quality and ops cannot get access to design engineering data within the same organisation in the same country. So this entire idea that International Aerospace industry will outsource components to Indian counter parts, which in turn will gain engineering know how and in turn will benefit local industry is beyond my comprehension. If I am wrong, great, but I have my apprehensions based on my experience.
I used to discuss this with sancho who was a great proponent of technology transfer driving local engineering development. Till date I maintain, there is no alternate to what we used to call "ragda",it roughly translates to sit down and relentlessly design. I pretty much owe everything to this philosophy, where engineer/s is/are given a system/design problem. Utilize 9 step to formulate strategy and 7 ways to for solution approach, and then sit down and design. No other task until you come up with the solution. This "ragda" strategy got us fuel increase in Mig21Bison, integration of jammer, integration for Mission computers, LCA aerofoil and aeroframe, pretty much all of the jigs and fixtures in HAL (albeit some of it was just by intuitive nature of engineering connect that the technicians had with the platform and production back then). I was programmed with this in formative days, so everytime I have to adapt a Tech Transfer i cringe at the G2. Purely from engineering standpoint, I will take an under-performing GTRX kaveri over a tech transfer GE 404, because I know more on my system that I have developed that I can ever know about a system I was donated by some other dude.
Apologize for the rant, I don't think this addresses your query. But apna hi thread hai.
