RE: Aero Help Needed!!! simulation and coefficients
Check out Robert C. Nelson's _Flight Stability and Automatic Control_. It's my favorite of the S+C texts out there for the very reason that is has a couple of tables that list equations for *estimating* all of the S+C derivatives. Be sure to use Nelson's conventions throughout, though, S+C gurus still haven't settled on a consistent universal set of nondimensionalizations and angle conventions.
MATLAB and Simulink are your friends. If you have MATLAB, PM me with your email address and I'll email you a MATLAB script that takes the geometric and flight condition inputs, calculates the derivatives, and constructs all the matrices for use with state-space simulation, as well as a simulink model with the state-space built and working...
