COEFFICIENTS !!!

Well for those of you who have a some idea of AERODYNAMICS would have heard of the terms like Coefficient of lift drag blah blah..
But for those innocent Homo-sapiens who are left yet untouched by this Great field this article may be an eye opener

All the forces and moments in Aircraft dynamics are defined in terms of Coefficients like coefficient of lift due to body i.e fuselage, coefficient of lift due to tail deflection, coefficient of drag due to aileron deflection and soooo on...

If you have to determine the dynamics of your vehicle then you need to identify the forces acting on it. Forces are defined by 12 fundamental non linear differential equations of motion.
In the end for an aerial vehicle to be completely characterized, you basically need all its AERODYNAMIC COEFFICIENTS.
Well these for a simple UAV they are about 50 to 70.(Depending in which frame you are using your equations).

It took Mr. Kaul 2 months to determine all of these and it was Captain Nigel M Jodeh at some airforce base in US , Dr. Robert Nelson and USAF Digital Datcom which rescued us.

So as of today Mr. KAUL is still checking his coefficients

Best of luck to him..
