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