REVERSING DEVICE OF OUTER LOOP OF GAS-TURBINE ENGINE Russian patent published in 2003 - IPC

FIELD: aircraft gas-turbine engines. SUBSTANCE: proposed reversing device contains fixed and movable housing and turnable flaps hinge-coupled by two-link leverage with front fixed housing. Turnable flaps consists of front and rear leaves hinge-coupled to each other, with spring placed in between. Spacers consisting of front and rear spacer are installed between flaps. Spacers are interconnected by hinge joints. Front ends of spacers are hinge-coupled with movable housing and telescopically connected with flaps. Ribs are made on outer ends of rear spacers. Rear leaves are made for contact with ribs in circumferential direction by their side surfaces. Ratio of axial displacement of movable housing 1 to height of ring channel of outer loop h is equal to 1.1-1.5. EFFECT: improved reliability of reversing device by reducing gas dynamic loads at reverse thrust. 4 dwg
