An Investigation of the Departure Modes of a F-4D Aircraft from a Steady Sideslip Flight Condition.

Abstract

This study consisted of modeling the motion of an F-4D with both the linear and non-linear equations of motion. The characteristic roots of the linear equations were first analyzed to predict the unstable flight conditions in the high angle of attack flight regime. The linear equations were then integrated to obtain a time history, and more explicit picture, of motion predicted by the characteristic roots when the aircraft is perturbed from the unstable condition. The validity of the linear equations is then checked and a more detailed picture of the nature of the motion obtained by numerically integrating the non-linear equations of motion at the same flight condition.
