Abstract : Dynamic models were ejected from the side and base of a carrier vehicle at Mach numbers of 2, 4, 5 and 8. Two capsule shapes were investigated in this program to enable determination of the effects of capsule geometry. The flared capsule confiquration was ballasted in two ways to pro vide two pitch moments of inertia. The cylindrical shape capsule possessed one moment of inertia. The data obtained from these ejections were in the form of high speed motion pictures. The Mach 2, 4, and 5 data were obtained through a Schlieren optical system. The Mach 8 data were obtained with a conventional high speed camera. All 55 data films were analyzed and trajectories are presented. Qualitative descriptions of the dynamic behavior and preliminary quantitative calculations were performed to compare the aerodynamic coefficients obtained from the dynamic tests with those obtained from static tests discussed in Volumes II and III.
