HI Everyone.
First of all, I'm not an aeronautical or mechanical engineer. I'm an electronics engineer but I'm currently doing a group project where I'm required to carry out a stability analysis on an aircraft that we've designed using the simulator software, X Plane.
I apologise in advance if any of these questions are stupid...
I know where the aircraft centre of gravity is but
How do I determine the Aerodynamic Centre of my aircraft?
I know that during steady flight, I must prove that all resultant moments acting around the centre of gravity should = 0, and
I've got Cm vs Alpha graphs for the tail airfoil (NACA 0009) and I'm in the process of trying to get the same graphs off X plane for the wing airfoils (Boeing Subsonic) but these will give me 2 completely separate moment coefficients for 2 different airfoils.
How do I get the Moment Coefficient about the Centre of Gravity from these?
Any help would be very gratefully received.
Thanks
