The Fourth Generation Escape System Technologies Demonstration Program was conducted to develop and demonstrate technologies that will enable the expansion of the escape envelope beyond that of current, third generation escape systems. The areas of the escape envelope in which expansion was demonstrated were escape under low-altitude, adverse-attitude conditions and escape at extremely high speed. The primary technologies that were developed for demonstration were: controllable propulsion, digital flight controls, and devices for crew member protection at high speed. The program was a two-phase program. In Phase I, two competing controllable propulsion subsystems were designed, developed, and demonstrated. A trade study was used to select the propulsion system, the digital flight control system, and the high-speed protection devices to demonstrate in Phase II. In Phase II, the new technology systems were integrated into an ejection seat test vehicle and a series of ten ejection tests were conducted at a high-speed test track. The tests successfully demonstrated safe escape at speeds up to 700 knots equivalent airspeed and at adverse conditions as severe as 20 degrees of yaw at 450 knots equivalent airspeed. The system also successfully demonstrated an upward-seeking trajectory resulting in a ground avoidance capability.
