Linear Perturbation Equations of Missiles in Pushover and Terminal Dive.

Abstract

In this report the linear perturbation equations of missiles are derived as they apply to the pushover and terminal flight phases. Starting with the most general perturbation equations of flight mechanics, simplifications are introduced that lead to nonautonomous linear differential equations. They are presented in a state-variable matrix format that is most convenient for flight control system analysis. A gravitational term, not previously considered, is included and shown to be of significant importance for vertical terminal dive. To validate the equations, selected time histories are compared with the results of a full-up nonlinear six-degree-of-freedom computer simulation. Good agreement is reached for the small angle range of interest for linear control system analysis. (Author)
