ABSTRACT:
An actuation system is provided for transferring axial motion into an interior of a gas turbine engine at a number of locations around an outer casing of the engine, with one synchronous movement. An external hydraulic actuator activates the system by rotating one outer crank which, in turn, rotates a single outer yoke. The yoke is mechanically linked to a plurality of crankshafts that extend through the outer casing of the engine and transmit rotational movement into the engine interior. The crankshafts are linked inside the engine to an annular sliding member causing that member to move axially. In one embodiment of this invention, the actuation system is used to open and close a slide valve between inner and outer bypass ducts of a variable cycle aircraft engine.
