I.D.# C1207Printable Description
Duration: .5 Day

This four-hour short course intends to present an overview of electrically powered flight control actuation systems, covering commercial applications. The scope covers issues related to the mechanical design of actuators themselves, with limited reference to their control electronics. Additionally, this course will provide participants an understanding of the design considerations behind these actuation systems.

Learning Objectives
By attending this seminar, you will be able to:

  • Explain electromechanical actuation systems in aircraft flight control systems
  • Identify key design considerations of electromechanical actuators
  • Identify a few key design considerations of electric actuator control electronics
  • Evaluate overall design considerations of electromechanical flight control actuation systems

Who Should Attend
This seminar is designed for engineers and other key personnel with little or no previous electromechanical flight control actuation knowledge.

Prerequisites
None.
