Abstract : The static moment of a symmetric missile is usually assumed to be single-valued although double-valued moments can occur: for example, a missile with a separated flow field. The quasi-linear analysis is generalized to treat the motion of a missile with a relatively simple double-valued static moment and cubic damping moments. The associated amplitude plane is discussed and the special case of planar motion is examined in detail. The quasi-linear frequency and damping are compared with exact values and conditions for the existence of planar limit cycles are stated. (Author)
