Hi, whether for a reversible or irreversible elevator control system, the current model needs some improvements, as in:
1) calculation of the "local" alpha at the elevator due to downwash effects of the wing/body, 2) determination of the elevator float angle for a "free stick" condition, and, 3) required elevator angle for the elevator positon and trim tab for balanced flight; i.e., pitch moment equal to zero 4) for control loading a force gradient base on stick displacement from the trimmed location, dynamic pressure, and g-loading The only parts lacking in the JSBSim as best as I can determine are some numbers to define the elevator aero coefficents, hinge moments as a function of tail alpha and deflection, and changes in the aspect ratio of the wing as a function of flap deflections that will be used to calculate the downwash for a specific wing configuration and flight condition Any comments??
