Abstract
Uose ?~~croasymmetry has been shown to determine the direction and magnitude of the large sideforce generated by a slender forebody at high angles of attack. It has also been shown that this force can cause the yawing moment characteristics of an advanced aircraft to vary between several highly nonlinear types, requiring extensive testing to define. The present paper shows that such extensive tests would he of little help, and that the coupling between vehicle motion and forebody flow separation, the so called moving-wall effect, will determine the characteristics in free flight.
