Abstract
An actuation system for a gas turbine engine is provided for axially translating an annular member such as a cylindrical sleeve valve of a variable area bypass injector (VABI). In one embodiment, the actuation system comprises a crankshaft rotatably attached at an outer casing of the engine for transmitting rotational movement. A crankarm is pivotally connected between the annular member and the crankshaft for transmitting rotation of the crankshaft to helical motion of the annular member. Two linkarms are circumferentially spaced from the crankarm, and are pivotally connected between the annular member and the outer casing. The linkarms are effective for synchronizing the motion of the annular member when the crankshaft is rotated.
