Abstract:

Large accelerations must be imposed upon an escape system in order for this system to rapidly leave the cockpit and safely clear the aircraft empennage. An upper bound to this acceleration-time history is imposed by the physiological limitations of the escape system occupant. The report contributes to the search for an optimum acceleration-time history which will, for a given physiological stress level, minimize the escape time and maximize the escape velocity. The authors conclude that an impulsive velocity spike, followed by a zero rise time constant acceleration, will give a 70 reduction in escape time, relative to present systems. Although this velocity profile is not shown to be the mathematically optimum form of excitation, it is the best of those investigated. Author
