Abstract : While the linear theory has been the backbone of ballistic missile design and has served with excellent success in its various forms over the years, recent spectacular missile flight failures have appeared unexpectedly and are unaccounted for by this linear theory. It is these flight failures which now require attention and consideration of the non-linearities in the fluid force and moment system which contribute to missile flight performance and dynamic stability. Two types of non-linear flight instability have been isolated and identified as NonLinear Magnus Instability, and Catastrophic Yaw. It is these 2 flight instabilities which will be discussed. Approximate mathematical models will be suggested for the evaluation of missile dynamic stability. Both experimental and analytical applications of these models will be made and discussed.
