FULLY-VARIABLE REACTIVE NOZZLE OF GAS-TURBINE ENGINE WITH ALL ASPECT THRUST VECTOR DEFLECTION Russian patent published in 2004 - IPC

FIELD: aircraft industry. SUBSTANCE: proposed reactive nozzle of gas-turbine engine has housing round in cross section with rims of narrowing and hinge-connected widening flaps and air ejector arranged coaxially with housing and made in from of two ring shells coaxially arranged behind exit section of nozzle housing, flaps and rims on inner and outer flaps hinge-connected to each other. First of rims is directly hinge connected to inner shell, and second rim is connected to shell by means of system of articulated tie-rods. Outer shell is hinge-connected with nozzle housing for turning by means of drive coupled with nozzle housing relative to horizontal axis square to longitudinal axis of nozzle. Shells are hinge-connected for turning relative to each other in vertical axis of nozzle by means of drive coupled with shells. EFFECT: improved economy and reliability of gas-turbine engine.
