Sensitivity of Aircraft Spinning Motion to Dynamic Cross-Coupling and Acceleration Derivatives
Abstract
An investigation was conducted to provide an insight into the importance of dynamic cross-coupling and acceleration derivatives in the spinning motion of fighter aircraft. The basic spinning motion of two aircraft was generated with a six-degree-of-freedom motion simulation program. The dynamic cross-coupling and acceleration derivatives were input into the program both individually and simultaneously to note their effect on the time history of spinning motion. Results of the study indicate that the dynamic derivatives can produce significant effects on the aircraft spinning motion and should be considered when conducting a spin analysis. The study also indicates that the spinning motion sensitivity to the dynamic cross-coupling and acceleration derivatives investigated is configuration dependent.
