S.S. White Technologies (Hall 4 Stand A4) has been selected to provide flexible rotary shafts for the Pratt & Whitney PW1000G engine’s nacelle. The shafts will transfer power on the variable area fan nozzle (VAFN) and synchronize actuators on the thrust reversers. The U.S. company has already provided two flexible rotary shafts for the thrust reverser rig, and previously supplied two flexible shafts for the VAFN test setup.

The PW1000G geared turbofan, which is to power the Bombardier CSeries, is the first to feature a VAFN. It is a variable duct that deploys at takeoff to increase the fan exit area. This protects the engine against possible fan resonance and flutter, according to nacelle manufacturer Goodrich. It also increases the bypass ratio, which helps to improve fuel efficiency.
