S.S. White Technologies Flexible Rotary Shafts Support Thrust Reverser Actuation Systems on CFM LEAP 1-A Turbofan Engines Selected by Scandinavian Airlines

March 5, 2021

S.S. White Technologies is the supplier of flexible shafts that transmit power to activate the critical Thrust Reverser Actuation Systems (TRAS) on the CFM LEAP 1-A turbofan engines selected by Scandinavian Airlines (SAS) to power their latest purchase of 35 Airbus A320neo aircraft. SAS is currently operating a total of 44 A320neo aircraft powered by LEAP 1-A turbofan engines.

S.S. White provides a set of flexible rotary shafts per LEAP 1-A TRAS that transfer power and enable safe operation during flight and deployment of the thrust reverser during landing.

In addition, all aerospace flexible shaft products are designed to one of the industry’s highest performance criteria by utilizing a unique computer modeling software program developed by S.S. White called Perflexion. This program allows the design engineers to more fully model the behavioral characteristics of the wire bundles within the shaft core and arrive at an optimum product that provides maximum bending flexibility and torsion strength while allowing minimal torsion deflection with up to a 30 percent improvement above current industry standards.
