摘要：A gas turbine engine (20), having an engine central longitudinal axis (A-A'),includes at least one of a vane support (142), a vane stage (146), a blade outer air sealsupport (152), and a blade outer air seal (134, 154). At least one of the vane support(142), the vane stage (146), the blade outer air seal support (152), and the blade outer airseal (134, 154) is rotatable about the engine central longitudinal axis (A-A'). The gasturbine engine (20) may further include a drive system configured to rotate at least oneof the vane support (142), the vane stage (146), the blade outer air seal support (152),and the blade outer air seal (134, 154) about the engine central longitudinal axis (A-A').
