AXISYMMETRIC SUPERSONIC JET PROPULSION NOZZLE WITH CHANGE OF ORIENTATION BY MEANS OF CONTROLLABLE RING

摘要

FIELD: turbojet engines. SUBSTANCE: in proposed axisymmetric supersonic jet propulsion nozzle of turbojet engine in which direction of thrust vector can be changed by means of controllable ring, according to invention, guide devices of ring for changing thrust vector have three cuts made along axis in feet secured on housing, whose middle planes intersect along axis of turbojet engine. Side walls of cuts serve as guides of three ball rollers secured on radial rods connected with thrust vector changing ring and arranged at equal distances from each other. EFFECT: provision of guide of thrust vector changing ring with use of three rails along which ring can move without wedging. 6 cl, 5 dwg
