Influence of Gravity and Applied Side Forces on the Stability of a Spinning Projectile.

Abstract

The non-linear equations of motion of a spinning projectile are linearised by a method different from that traditionally used. This results in extra terms being retained, giving a more complete description of the shell behaviour and revealing some new information on stability. The resulting equations are solved as an eigenvalue problem, since this method of solution is the least tortuous and produces a good insight into the dynamic behaviour of the shell. It is found that the stability of the precessional and nutational modes is influenced by gravity and applied side forces. Results of numerical simulations which confirm these conclusions are given.
