Abstract : TWO STATIC DEVELOPMENT FIRINGS AND FOUR STATIC DEMONSTRATION FIRINGS WERE CONDUCTED ON THE LW-1 escape system. The development firings were required to define the lateral rocket thrust moment arm and to perfect the separation latch assembly. The demonstration firings proved the system's recovery capabilities under zero attitude, zero speed condtions. Analytical substantiation of recovery at velocities up to 300 knots is presented. Catapult acceleration forces are less than 2 G's with rates of onset of acceleration less than 250 G's/second. Maximum sink rate and angle of dive recovery capabilities are achieved by the immediate allistic deployment of the personnel parachute. Design simplicity minimizes maintenance reqirements. Design simplicity and redundant gas systems optimize reiability.
