Abstract : Equations are formulated for a hypothetical fighter/close support VTOL aircraft which will simulate a realistically severe crew station escape environment arising from aircraft failures in the VTOL AND HIGH SPEED, LOW ALTITUDE FLIGHT REGIMES. Four candidate airplanes with dissimilar propulsive and control concepts are analyzed and a lift-fan configuration selected to test the feasibility of any crew escape concept. Plotted time histories are presented of aircraft and crew station positions, rates, and accelerations occurring as a consequence of various failure modes. The time histories are summarized to reveal the extreme conditions encountered during VTOL and high speed emergencies, conditions for which existing escape systems are not designed. (Author)
