Hi dear
@The Deterrent
I really do not think memes and smilies are needed in a serious discussions. It would be great if we can avoid it here. Instead of getting riled up, kindly prove your point based on facts and established literature-- but I know you can not prove-- there is a difference between "proving" and "speculating". I am unfortunately not much into the latter.
As for the Babur, there are a plethora of literature available on the origins and development. Please lets not tread that path or else it will very easily turn into mud-slinging competition between two groups who I am sure would have never worked on any aerial vehicle in any capacity.
btw, do you really know what it takes to design a cruise missile? Does pakistan even have a certifying agency to certify the hardware and software for cruise missiles?
It is a fact--if you care to go through various American publications-- that a lot of KH-55 were indeed transferred to China in early 90s and also couple of un-exploded tomhawks(via pakistan in early 2000s). Now once you have a physical model-- you can create your own similar model and pass it through numerous wind tunnel tests at various AoAs, Side slip angles etc etc to create a matrix of data(Various Aerodynamic Coefficients). Various curve fitting techniques are then brought to bear to make out a relationship between aerodynamic coefficients and variables like alpha, beta, elevator deflection, rudder deflection, roll rates etc etc. Once you have these relationships, you can then linearize your model, about lets say level flight condition and then design a simple linear control. I am not sure if pakistan has even once passed the Babur through wind tunnel tests etc.
You would be guessing, as to why one can not use traditional off the shelf autopilots such as APM or PX4,right? Well they simply do not meet the stringent mil requirements. For a cruise missile you would have to design your own control and integrate it with a mission planner. The hardware and software should both adhere to mil requirements.
PS- Kindly note, I do not quote any Indian source just to make it neutral. All of my observations are based on either American or European sources. Also note I am not claiming that pakistan did nothing, Pakistan did infact work out ababeel almost entirely on their own-- which is a commendable job, although in cruise missiles, I do believe that it was China which had active help in Babur and South Africa that helped in Ra'ad.
