Ejection seat system differential equations are derived which describe the system trajectories from escape initiation to crew recovery. The equations are solved by digital computer through a numerical integration algorithm, and time history plots are presented for preliminary design information. Trajectory dynamics are computed for the seat as it is catapuled along a set of flexible rails constrained to translate with the aircraft. The impetus of seat-rail separation is simulated, and the airplane and seat trajectories are portrayed as the seat responds to a sequence of forces from rockets and parachutes. Acceleration loads on the man are computed throughout the time history, demonstrating the effects of parachute projection, snatch forces, and opening shocks as well as catapult and sustainer rocket forces. A comparative analysis of catapult and sustainer rocket techniques is included. Author
