I hope i posted on the right forum...
I've been considering writing a simple(?) R/C flight simulator for quite some time. After reading about aerodynamics i concluded that a simulation software are bound to make great simplifications, and may only model a subset of the actual physics involved. However, there seem to be very little written on the subject, when it comes to good simplified simulation software for planes. Any pointers would be most welcome. Perhaps there are some GPL projects that has related simulation models? Thanks in advance, Mike

I'm a total rookie on flight dynamics. I have better understanding of general physics, as I've spent a few years working with AI based games and 3D rendering engines. Honestly, after spending about 30 hours on the net reading about aerodynamics, i felt discouraged by the complexity  it appears mankind still don't know exactly why we can fly =) Indeed, reading a few books on the subject would be a good thing. However, i was hoping to find some shortcuts in terms of simplified, easy to understand, simulation models that would be a good starting point. Perhaps in the long run, simulation could be refined with experience and knowledge. I found the sss project (GPL) that has some pointers. Unfortunately, very little documentation exists on the actual flight simulation and the theory behind it. Any help is most welcome! Thanks, Mike

R/C plane simulation
http://www.princeton.edu/~stengel/MAE331.html As a first cut, you may want to consider a very simple linearized simulation.

I have started reading and find it quite easy to follow, though some explanations would help. I stumbled on some very simple equations on this NASA page: Thrust = m(dot) V Lift = k V^2 A cl Drag = k V^2 A cd where k is Smeaton's coefficient (.00327), cl is the lift coefficient and cd is the drag coefficient. Are this equations (and some basic newton stuff) to far simplified for being useful in a first attempt? /Mike
