Systems and Methods to Control Variable Stator Vanes in Gas Turbine Engines

摘要

Embodiments of the present application include a variable stator vanes control mechanism for a gas turbine engine. The control mechanism may include a moveable actuation rod in operative communication with a torque shaft such that movement of the actuation rod rotates the torque shaft. The control mechanism also may include a first unison ring in operative communication with the torque shaft such that rotation of the torque shaft drives the first unison ring. Moreover, the control mechanism may include a second unison ring in operative communication with the torque shaft such that rotation of the torque shaft drives the second unison ring.
