AXISYMMETRIC SUPERSONIC REACTION NOZZLE Russian patent published in 2003 - IPC

FIELD: turbojet engines. SUBSTANCE: proposed axisymmetric supersonic reaction nozzle of turbojet engine contains rim of convergent flaps and rim of divergent flaps. Divergent flaps are additionally coupled with thrust vector control ring set into motion by several power cylinders to provide adjusting of outlet cross section of divergent part and deflecting flow of discharge gases. Power cylinders are connected with thrust vector control ring by means of ball joint and are secured on fixed structure to take up tangential forces acting from side of discharged gas flow onto divergent to provide positioning of thrust vector control ring. Proposed invention makes it possible to combine on power drive the functions of control and positioning of thrust vector control ring and take up side forces caused by deflection of vector of discharged gas flow. EFFECT: improved quality of nozzle. 8 cl, 6 dwg
