The quasi-linear analysis which has been successfully applied to the nonlinear angular motion of symmetric missiles is extended to include the nonlinear motion of slightly asymmetric missiles. This analysis indicates the existence of three special spin rates - zero spin, resonant spin, and approximately three times resonant spin. The exact solution for the small amplitude motion about a large trim angle of a nonspinning missile with a cubic static moment is obtained and the quasi-linear relations are shown to agree well with this exact result. Relations for a cubic damping moment and a cubic lift force are derived. Author
