Aerodynamic Trim Conditions
Aerodynamic Trim Conditions
(OP)
Hello all,I have a program which requires input such as Velocity, Angle of attack, and Fin deflection.
The program goes through and calculates the aerodynamic coefficients for my vehicle, then outputs my Forces and Moments on the body (Fx, Fy, Fz, Mx, My, Mz).
I need to make a "wrapper" of sorts that can find the trim conditions of my Vehicle. In other words, I would like to set my Moments all equal to zero, and have the trim wrapper iterate until it finds what fin deflection will give M = 0.
Is it possible to do some sort of numerical analysis in Matlab to do this? I am not sure where to start, is there a paticular method I should be looking at to do this?
Thanks in advance for your thoughts.

RE: Aerodynamic Trim Conditions
trimmed flight, IMHO, refers to the pilot adjusting the trim controls to save having to keep a constant load on the sitck to maintain the flight attitude he wants. also i think trim tabs create the required lift with less drag.
