Flexible Rotary Shafts Drive Flap & Slat Actuation Systems on Embraer 145 Business Jets
S.S. White Technologies is the aerospace industry’s leading performance-driven producer of aerospace flexible rotary shafts for the flap and slat systems on the Embraer 145 business jet platforms.
industry’s leading performance-
shafts for the flap and slat systems on the Embraer 145 business jet platforms.
The aircraft’s “flight control system power drive units” in the wing sections
transfer power through a series of flexible shafts that rotate to activate linear
actuators to control the flaps and slats through a series of precise operating
positions from full “extend” to full “retract” during flight.
S.S. White’s POWER-FLEX aerospace qualified flexible rotary shafts are
uniquely engineered to transmit the proper amount of torque to the linear
actuators to control the precise position of the slat and flap surfaces especially
during take-off and landing. Extending the flaps and slats increases the wing
surface area generating more lift at low speeds. Retracting them reduces wing
area and drag at higher flight speeds to increase performance and efficiency.
In addition, all aerospace flexible shaft products are designed to one of the
industry’s highest performance criteria by utilizing a unique computer modeling
program developed by S. S. White called PERFLEXION. This program allows
design engineers to 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 torsional strength while allowing minimal torsional
deflection with up to a 30 percent improvement above accepted industry
S.S. White Technologies is a world leader in the design, engineering,
manufacture and testing of a wide variety of flexible shaft products for the
aerospace, medical, automotive and industrial markets around the globe. .
Almost all of the commercial and military aircraft platforms in the air today
(except Russian) and more than one-half of US manufactured cars rely on S.S.
White Technologies flexible shaft products. The company currently has
manufacturing facilities in the United States, the United Kingdom and India.
