HARMONIC DRIVE ACTUATOR FOR VARIABLE VANES

An actuator system (118E) includes a harmonic drive (122) operable to drive a variable vane system of a gas turbine engine (20). The harmonic drive (122) drives a shaft (200) that drives first and second actuator gears (210, 214) of first and second variable vane stages (212, 216).
