Abstract : IN Ballistic Research Laboratories rept. no. 1114 (AD-247 271) the nonlinear motion of symmetric missiles was analyzed by means of a perturbation technique. Owing to the algebraic complexity of this technique, it was only applied to the relatively simple problem of nearly circular motion. This report shows that the planar motion of nonspinning symmetric missiles possesses similar algebraic simplicity. The influence of various cubic static and damping moments is investigated in detail. Planar limit oscillations about a trim angle are found to exist under certain conditions. Finally, the analysis is combined with the almost circular motion analysis of BRL report no. 1114 to determine the basic features of the complete generalized amplitude plane. (Author)
