So much professed superiority and presumptions but we don't even have a single turbine engine in operation today.
Let's get this straight. We all yearn for the same thing. The fate of KAAN and the nation's independence is contingent on this engine. Any dose of optimism or pessimism does not call into question of someone's loyalty or his enthusiasm.
The ability of producing blisks or single-crystal superalloys do not automatically translate to design and production capability of a complete large 5th gen turbofan engine. Unlike some other countries, to solve a single problem we need to solve 100 other problems due to our lack of infrastructure and know-how.
All these problems and the ones we haven't faced yet will be solved if the money and the will is there. However, the crux of the matter is the
timeframe.
Just one last note, a prototype and deliverable product are two vastly different things. This is especially true for the non-legacy players like us.
