EJECTION SEAT Russian patent published in 1995 - IPC

FIELD: aeronautical and space engineering. SUBSTANCE: ejection seat has head-rest with emergency parachute arranged in it, parachute deployment pyrosystem, parachute devices with mechanisms for switching them on, first stabilizing rods with deployment pyrosystem mounted in vicinity of head-rest, seat, crew member restraint harness, gun mechanism, first booster engine with swivelling nozzle and pyromechanism for turning it, system for separating crew member from seat, self-contained power supply source, seat automatic system, device for switching on the seat automatic system, second booster engine with swivelling nozzle and pyromechanism for turning it mounted under seat and secured to it by means of locks; second stabilizing rods with deployment pyrosystem mounted on second booster engine whose plane passes through center of masses of "ejection seat crew member" system, second booster engine separation system mounted on it. Restraint harness, pyromechanism of first booster engine nozzle, pyromechanism of second booster engine, self-contained power supply source and gun mechanism are electrically connected with on-board automatic system and seat automatic system is electrically connected with device for switching it on, self-contained power supply source, first booster engine, second booster engine with pyrosystem for deployment of first stabilizing rods with pyrosystem for deployment of second stabilizing rods, with second booster engine separation system and with mechanisms for switching on the parachute devices. Seat automatic system consists of switching unit and time programming device. Mounted on second booster engine is device for making the electric circuit which is electrically connected with self-contained power supply source and with electric pyro cartridges of igniter of second booster engine. Separation system consists of pyroinitiator connected with two telescopic cylinders by means of pipe line. Telescopic cylinders have electric pyro cartridges whose chambers are brought in communication with chambers of rods. Pyro initiator is electrically connected with seat automatic system and electric pyro cartridges of cylinders are electrically connected with on-board automatic system. EFFECT: safe escape from space vehicle in case of emergency at launch, injection, re-entry and landing stages. 5 cl, 14 dwg
