Design Considerations for Electrohydrostatic Actuators C1304
Topics: Quality, Safety & Maintenance
This course is verified by Probitas Authentication as meeting the AS9104/3A requirements for continuing Professional Development.
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 course you will be able to:
- Describe the evolution of EHA for aircraft flight controls

- 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 course 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, other key personnel desiring an understanding of aircraft electrohydrostatic actuation systems will benefit.
You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
Jérôme Socheleau or Dominique van den Bossche
Jérôme Socheleau currently serves as the Head of Systems Group at UTAS Actuation Systems in France. He has been working for more than 20 years in Aircraft Primary Flight Controls domain; he was in charge of the development of several primary flight control actuation systems for new aircraft involving the state of the art "Fly By Wire" technology on A340-500/600 and the introduction of first EHAs on A380. Additionally, Mr. Socheleau led the design of several advanced primary flight control actuator prototypes in the field of Research and Technology projects, these include hybrid Electrically Assisted Hydraulic Actuator (EAHA), which enables hydraulic and electric power summing in a single actuator hydraulic power ram, and also the TRL6 demonstration of several ElectroMechanical Actuator (EMA) for Primary Flight Control Actuation. He is currently responsible of Systems activities development for UTAS in France, his teams are involved in R&T activities including Power Drive Electronics and Flight Control electronics as well as EMA, they are additionally in charge of products development for new platforms such as Embraer KC-390 and Irkut MC-21. At last, Mr. Socheleau is the current vice chairperson for the SAE A6B2 Electrohydrostatic Actuation Panel aimed at providing guidelines and recommended practices for EHA design and use. He received a Master’s Degree in Aeronautics at the French Engineering School “Ecole Nationale Supérieure de Mécanique et d’Aérotechnique” at Poitiers.
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 Aéronautiques. 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 École Nationale Supérieure D'ingénieurs de Constructions Aéronautiques.
