Hi
@MastanKhan
You're right, I just wish to elaborate on what you said, Failures are a part of R&D venture. It is impossible to design a new product or technology without facing failures. A lot of Pakistanis on this forum are so painfully oblivious to research and general engineering practices(for instance I've read how hard were you trying to explain trimming to general folks here) that they would argue if somehow your views doesnt fall in line with theirs. No I am not bashing, it is just my personal observation.
India or Pakistan are not exception to this time tested rule. India faced numerous challenges in gas turbines right from acoustic instability, screeching to now metallurgy. And after having spent nearly $700mn on various Gas Turbine related R&D, Kaveri still cant substitute GE404 on Tejas. However it taught various valuable lessons to the GTRE team(I've had interactions with them at def expo-2018). It also spawned off various programs as mentioned in my previous post. One of the programs particularly that of micro turbine for cruise missile applications is going smoothly and will be integrated onto the CM sooner than expected.
The problem with Pakistan is that it is as opaque as a brick when it comes to anything related to defence. It is not like India wherein there exists a CAG(fully autonomous body) that regularly audits and writes scathing reports on the state(delays, shortcomings etc) of many defence programs etc. So, in absence of such a system, Pakistani audience in general tend to believe whatever fancy story they find comfort and solace in. This thought process permeates through even those who are living in west and those who have some exposure to such system of checks and balances.
A lot of people do not know that one would need dedicated research facilities and billions of dollars to design a system. For instance in order to design lets say a CM, they would have to first start with the mission which dictates the kind of endurance and range required. In order to meet that kind of endurance/range, you select the power plant. Then you pass your dummy CM model through numerous wind tunnel tests to find out various stability, control and damping derivatives. Once that is done, you begin the system level engineering design right from electronics, actuators, composites, warheads etc etc. It is at this stage, you need the industrial maturity to source these components from local industry.
