S.S. White Technologies (Hall 6, Stand C9) has won a contract from Honeywell Aerospace to supply flexible rotary shafts for the starter air valve on the GE9X. Specially designed to transmit rotary torque for the manual override of the starter air valve, the flexible shaft allows ground crews to manually actuate the Honeywell component in case of an operational failure.

The starter air valve controls air flow from the engine bleed, APU or ground supply to the air turbine starter.

S.S. White uses a unique computer modeling software program it developed call Perflexion to design all its flexible shaft products. The program allows engineers to more fully model the behavioral characteristics of the wire bundles within the shaft core and arrive at a product with maximum flexibility and torsion strength.

At the show, S.S. White is displaying several rotary shaft applications and senior management and engineers are available to demonstrate the technology and address various product applications.
