Abstract : Equations based on Newtonian impact theory have been derived and a computational procedure developed which enables the determination of the aerodynamic forces and moments acting on arbitrary bodies of revolution with nondecreasing cross-sectional area distributions undergoing either separate or combined angle-of-attack and pitching motions. The analysis considers variations in angle of attack from minus 90 degrees to 90 degrees and allows for both positive and negative pitching velocities of arbitrary magnitude. The results are also directly applicable to bodies in either separate or combined sideslip and yawing maneuvers. (Author)
