Aerospace Hydraulic Components C1421

SAE International is pleased to offer this professional development seminar in conjunction with the SAE A-6 Aerospace Actuation, Control and Fluid Power Systems Committee meeting Oct. 20-23 Santa Barbara, CA.

This 4 hour short course will provide an overview of the hydraulic components used on aircraft. There will be a brief overview of hydraulics, aircraft hydraulic systems, and aircraft flight controls. You will learn the function of each component used within the hydraulic system, and then look in depth at each component"s design.

Jeffrey C. Dickey

Jeffrey C. Dickey is Executive Vice President - Hydraulics for The Lee Company, a manufacturer of high precision miniature hydraulics components used in the aerospace, medical, and industrial industries. He is responsible for seven business units, overseeing both engineering and manufacturing. Mr. Dickey has been designing hydraulic components since 1986, starting as a project engineer and working his way up to his current position. He has designed and developed an array of proprietary hydraulic component designs for plugs, restrictors, check valves, pressure relief valves, flow regulating valves, pressure regulating valves, pilot operated valves, shuttle valves, bypass valves, solenoid valves, etc. His designs have helped solve issues within hydraulic systems for aerospace, medical implants, military vehicles, missiles, satellites, submarines, down-hole oil tools, formula 1 race cars, etc. He has Patents on a High-Pressure Pin Plug (Patent 4867333) and Expansion Sealing Device (Patent 5121947). He is an active member of the SAE - A6 Fluid Power, Actuation and Control Technology Committee. He is currently the Panel Chairman of the A6C5 Components Panel, and Co-Author of SAE Paper 912134 "Total Flexibility in Cartridge Valve Porting Through Innovative Sealing Technology". Mr. Dickey received his B.S. in Mechanical Engineering from the University of Connecticut.
