ADJUSTING THRUST VECTOR OF EJECTION SEAT ROCKET MOTOR

摘要

For adjustment of the direction of its thrust vector, an ejection seat rocket motor is mounted on the ejectable frame element for bodily angular motion, or has an adjustable gas deflector. The seat element, heightwise adjustable on the frame element, has a motion transmitting connection with the rocket motor whereby the thrust vector is maintained in desired relation to the center of gravity of the seat/occupant mass in every position of seat adjustment. At high speeds an airspeed responsive member transiently engages, during ejection, a sensing member associated with said connection, modifying the thrust vector adjustment.
