Design Considerations for Electrohydrostatic Actuators

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.
