Key Considerations for the Comparison of Power‐by‐Wire and Hydraulically Supplied Solutions for Aerospace Actuation C2307

Topics: Quality, Safety & Maintenance


This four-hour, instructor-led course provides key considerations for the comparison of electrically supplied (Power-by-Wire, or PbW) and hydraulically supplied (Power-by-Pipe, of PbP) actuation for aerospace. The focus is put on the consequence, for designers, of changing the physical principles and the technology used. A particular attention is paid to the unavoidable side effects introduced by the technological realization. Simple examples with realistic numerical values are used to make the comparisons quantitatively realistic.

Learning Objectives

By attending this course, you will be able to:

  • Understand, explain and compare the functional and technological architectures of the different types of actuators (EHSA, EHA/EBHA, EMA)
  • Identify and understand the main differences between actuators concerning
    • the control of power, power management and protection functions
    • the key design drivers for power sizing, thermal balance and control design
    • the technology‐related differences in side effect and natural dynamics
    • the actuator/load/airframe integration

Who Should Attend

This course is designed for engineers and other key personnel who want to get preliminary considerations for comparing the merits and drawbacks of conventional hydraulic actuation and PbW actuation.

Prerequisites

A basic knowledge of hydraulics and electric‐drives will be beneficial, but is not requested.

You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
