An emergency landing system for an aircraft, particularly a helicopter, in which a plurality of rocket members are mounted on the fuselage of the aircraft and directed downward about the center of gravity of the fuselage. The rocket members are activated to direct upward reactive forces by the energization of a proximity switch located on the fuselage and adapted to sense the ground level when the fuselage has descended within a predetermined elevation above the ground level so that the downward movement of a disabled aircraft is substantially decelerate...
An emergency landing system for a helicopter, comprising: (a) a helicopter fuselage having top and bottom surfaces and a center of gravity, (b) a plurality of rocket members, each having a discharge end and a rocket actuator for creating a reactive force, (c) means mounting said rocket members on said fuselage at spaced intervals about said center of gravity so that said discharge ends are directed downward, (d) proximity switch means on said fuselage adapted to sense the ground level below said fuselage and having operative and inoperative modes, said s...
