Abstract
The behavior indicated in Figs. 3 and 4 suggests that a small shape change would occur with each pitch oscillation of the vehicle, so that the resulting trim moments would tend to cancel out. If the net trim remained sufficiently small, then the epicyclic motion would persist until it damped out from inherent pitch and normal force damping. Because successive points of minimum ! I and presumed shape change occur on essentially opposite meridians (from the point of view of an observer fixed in space), the lift nonaveraging dispersion associated with equal increments of shape change should be minimal.' It is emphasized that these conclusions are based on the assumption that very small incipient ablation or erosion asymmetries exist which do not influence the motion. A more rigorous treatment of the problem should include the effects of these shape asymmetries on the coupling between the angle of attack and windward-meridian rotation rate.
