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.
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.
The company says that all aerospace flexible shaft products are designed to one of the industry’s “highest performance criteria” by utilising a “unique” computer modelling software program developed by S.S. White called PERFLEXION.
This program allows the design engineers to more fully model the behavioural 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.
