Design Considerations for Electrohydrostatic Actuators C1304

<p> <i><b>SAE International is pleased to offer this professional development seminar in conjunction with the Joint Technical Committee Week combining the SAE A-5 Aerospace Landing Gear Systems and SAE A-6 Aerospace Actuation, Control and Fluid Power Systems Committee meetings scheduled for October 26 - 30, 2015 in Honolulu, Hawaii. </b></i></p>

This four hour short course will provide an overview of design considerations for electrohydrostatic actuation for transport and business aircraft applications.  The instructor will present the critical topics of electrohydrostatic actuation (EHA) from a systems development perspective (V-Approach).  Beginning with aircraft system requirements, the instructors will then guide participants through EHA subsystem requirements, component design, component verification test, aircraft integration, and use.  Also included will be a short history of the evolution of EHA technology, and an overview of the advantages and system tradeoffs for selection of electrohydrostatic actuation on aircraft.

Learning Objectives

By attending this seminar, you will:

  • Describe the evolution of EHA for aircraft flight controls
  • Evaluate the unique advantages/disadvantages of EHA in flight control applications
  • Establish an awareness of high level aircraft system and requirements for EHA
  • Explain basic design considerations for EHA
  • Identify unique test and verification methodologies for EHA
  • Describe important considerations for aircraft integration
  • Evaluate key lessons learned about EHA development and aircraft usage


Who Should Attend
This seminar is intended for engineers and other key personnel involved in the design and specification of hydraulically powered flight and utility control actuation systems including fluid power, electrical, and systems engineering disciplines and those involved with aircraft certification.  In addition, this seminar will benefit other key personnel desiring an understanding of aircraft electrohydrostatic actuation systems.

Dominique van den Bossche

Dominique van den Bossche is presently an independent consultant for European and US flight control actuation companies. He retired from Airbus in 2009 as the Head of Department in charge of the Primary Flight Control Actuation and Hydraulics Department in the Systems and Integration Tests Center of Competence of the Airbus Engineering organization. He was responsible for the management of R&T, design, development, validation and in-service engineering support of the Primary Flight Control Actuation, Hydraulic Generation and Hydraulic Distribution equipment, for all Airbus models from A300B to A380, A400M and A350. Previously at Aerospatiale, Mr. van den Bossche was a development engineer in charge of A300B hydromechanical flight control equipment. He was also involved in the A310, A300-600, ATR42/72 and A320 flight control equipment developments. He was appointed as the Head of the Pilot Controls and Primary Flight Control Actuation Group prior to his appointment to Head of Department. Holding four patents involving flight control actuation equipment design and application, Mr. van den Bossche has also been recognized with an award by the French Academy of Technology for his achievements on electrohydrostatic actuation technology. In addition to actively serving on the SAE-A6 Fluid Power, Actuation & Control Technology as Vice-Chairman, his industry service also includes serving on the ISO TC20/ SC10/WG9 Hydraulics & Flight Control Actuation committee and the Mechanical Branch Committee and Hydraulic & Actuation working group of the French “Bureau de Normalisation Aéronautique”. He currently teaches Flight Control Actuation Systems at the Institut Universitaire de Technologie (IUT) in Blagnac, France and on-demand courses for various companies and organizations. Mr. van den Bossche received a Master's Degree in Aeronautics at the French “Ecole Nationale Supérieure d' Ingénieurs de Constructions Aéronautiques”.
