Abstract:

Methods, ranging from rigorous and complicated to simple and approximate, are presented for estimating flying qualities in accordance with such specifications as MIL-F-8785 ASG. Aerodynamic and inertial data are assumed to be known. Intended mainly for design use, the report gives enough detail to indicate derivations and conditions for validity. Topics include the static and dynamic, controls-fixed and controls-free aspects of aircraft stability, control, and trim. Although emphasis is on linear analysis, methods are given or indicated for such nonlinear problems as drag, pitch-up, inertial coupling, and spinning. Appendixes give an introduction to aeroelastic effects, ways to analyze control tabs, a derivation of the controls-free equations of motion, and an introduction to root locus analysis. Author
