Hint: One way of doing so, is to randomly choose a major subsystem, say (just purely as an example) HPT. Now if you search around carefully for
1) What are it's major subcomponents? Should be fairly easy.
2) What are the material and manufacturing (and some design level data) tech required to manufacturing required for these sub-components
(and don't forget the integration technologies as well)
3) What level of requirement-vs-achieved perf data (and some level of design data) will the OEM be ready to part with?
Remember some level of perf data will be available to the user anyway.
4) Is there any indigenous program that may have delivered or demonstrated equivalent level of technology mastering
... and so on and so forth!!
Should be a good mental exercise, isn't it?
