S.S. White Flexible Rotary Shafts Drive Flap Actuation Systems on the Embraer Phenom 100 & 300 Jets

Oct. 18, 2012 - PRLog -- Piscataway, New Jersey --- S.S. White Technologies is the aerospace
industry’s leading performance-driven producer of aerospace flexible rotary
shafts for the flap systems on the Embraer Phenom 100 and 300 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 through a series of precise operating positions from
full “extend” to full “retract” during flight.

S.S. White’s POWER-FLEX aerospace qualified flexible shafts are uniquely
engineered to transmit the proper amount of torque to the linear actuators to
control the precise position of the flap surfaces especially during take-off and
landing.  Extending the flaps 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
standards.
