Compressor variable stage remote actuation for turbine engine
Abstract:
A turbine engine locates an actuator (55) for the compressor variable guide vanes (54a, b, c) at a location remote from the variable guide vanes. The actuator is connected to the variable guide vanes through a torque rod (56) inside an inlet guide vane. The torque rod rotatably drives an activation ring (57) about the engine centerline. The activation ring is coupled to each of the variable compressor vanes via linkage, such that rotation of the activation ring about the engine centerline causes all of the variable compressor vanes to pivot. With this configuration, a tip turbine engine can be more easily provided with variable compressor vanes for the axial compressor.
