Abstract (en)

Embodiments of the present application include a variable stator vanes control mechanism (100) for a gas turbine engine. The control mechanism (100) includes a moveable actuation rod (102) in operative communication with a first unison ring (104) such that movement of the actuation rod (102) drives the first unison ring (104). The control mechanism (100) also includes a linkage (114) in operative communication with the first unison ring (104) and a second unison ring (116) such that movement of the first unison ring (104) drives the second unison ring (116).
