METHOD OF OPERATION OF ROTATING ROUND SUPERSONIC REACTION NOZZLE OF TURBOJET ENGINE AND DEVICE FOR IMPLEMENTING THIS METHOD Russian patent published in 2000 - IPC

FIELD: aviation industry; reaction nozzles of turbojet engines. SUBSTANCE: outer movable ring is turned relative to two-support trunnions at changing of direction of thrust vector in vertical plane. Force from outer movable ring is transmitted to inner movable ring through two axle-shafts of ring hinge joint, thus making inner movable ring turn together with outer ring through the same angle. In its turn, inner movable ring turns nozzle critical section and supersonic part changing mechanism through the same angle by means of subsonic insert, thus changing direction of nozzle thrust vector in vertical plane. For changing direction of thrust vector in horizontal plane, inner movable ring is turned relative to outer ring in horizontal plane area by additional control cylinders, inner movable ring being turned around axle-shafts of ring hinge joint. In its turn, inner movable ring turns nozzle critical section and supersonic part changing mechanism through the same angle by subsonic insert coupled with inner movable ring which provides changing of direction of nozzle thrust vector in horizontal plane. EFFECT: provision of independent turning of nozzle in vertical and horizontal planes and axial symmetry of nozzle being turned in either side. 5 cl, 5 dwg
