Design Considerations for Hydraulically Powered Fly-By-Wire Flight Control Actuation Systems C1132


This four-hour short course will present an overview of hydraulically powered flight control actuation systems used on fly-by-wire aircraft, covering both military and commercial applications. The scope this course covers the issues related to the mechanical design of actuators themselves, as well as their control electronics. Additionally, this course will provide participants an overview of the design considerations behind these flight control actuation systems.


Learning Objectives
By attending this seminar, you will be able to:
  • Explain flight control actuation systems in military and commercial aircraft fly-by-wire systems
  • Identify key design considerations of control actuators
  • Identify the design considerations of actuator control electronics
  • Evaluate overall design considerations of flight control actuation systems

W. Scott Schaefer

W. Scott Schaefer has been employed at Moog Inc. since 1983, mostly in the aircraft flight control arena. He has held various management and engineering positions, including key positions in the development of various aircraft actuation systems, including the DHC-8, X-¬29, B-2, V-22, F-35, B-787 and KC-46 refueling boom. Before joining Moog, Mr. Schaefer was a Senior Systems Engineer at Link Aviation where he helped develop motion systems and control loading systems for Link's line of flight simulators. He is a member of the SAE- A-6 Aerospace Actuation, Control and Fluid Power Systems committee and is currently the Chairman of the Actuation and Control subcommittee. Since 1993, Mr. Schaefer has held offices in a number of committees and sponsored numerous technical documents. He received both his B.S. and M.S. degrees in Mechanical Engineering from The Ohio State University and also an MBA from the State University of New York at Binghamton.
