Abstract

A nonlinear differential equation representing the initial nutational vibrations of a spinning projectile in the presence of a nonlinear Magnus moment has been approximated by a perturbed Duffing’s equation and the quantitative and qualitative agreement of the approximation brought out. Then the combined motion in nutation and precession has been examined and sufficient conditions for the Magnus instability of the normal motion establishedvia Lyapunov’s second method.
