Aircrew Automated Escape System Simulation Model

Abstract

A math model is presented for simulating the performance of the SEU-3/A Ejection Seat Escape System which employs propulsion, parachute, and stabilization subsystems. Seat/man, man alone, and seat alone configurations are treated as rigid bodies in six degrees-of-freedom. "Canopy first" recovery parachute deployment by rocket and/or drogue parachute is modelled as well as "lines first" drouge deployment. Parachute opening equations are treated in detail, and riser/suspension line forces are assumed to be elastic. In addition, an aircraft model is formulated.
