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 includes a moveable actuation rod in operative communication with a first unison ring such that movement of the actuation rod drives the first unison ring. The control mechanism also includes a bell crank mechanism in operative communication with the first unison ring and a second unison ring such that movement of the first unison ring drives the second unison ring.

主权项

1. A variable stator vanes control mechanism for a gas turbine engine, comprising:
a first unison ring; a second unison ring; a moveable actuation rod in operative communication with the first unison ring such that movement of the actuation rod drives the first unison ring in a first direction; and a bell crank mechanism in operative communication with the first unison ring and the second unison ring such that movement of the first unison ring in the first direction drives the second unison ring in a second direction.
