Introduction to Aircraft Hydraulic System Design and Certification C1205
Topics: Quality, Safety & Maintenance
This four-hour short course provides an overview of hydraulic system design of typical business and commercial aircraft. Topics will include the principles, system architectures, power sources, and the main components and technologies of hydraulic systems including hydraulic power generation, filtration, fluid storage, distribution, sensing and control. The step by step process of designing a hydraulic system will also be reviewed. Additionally, future trends in hydraulic systems will be discussed.
Learning Objectives
By attending this course, you will be able to:
- Explain the operating principles and design process of an aircraft hydraulic system
- Identify system architectures attributes, including those that affect aircraft safety
- Identify power sources for hydraulic systems and how they operate
- Identify the various components of hydraulic systems
- Describe the hydraulic system design and certification process
Who Should Attend
This course is designed for engineers, program managers, executives, and other key personnel with little or no previous hydraulic system knowledge or experience.
Prerequisites
None
You must complete all course contact hours and successfully pass the learning assessment to obtain CEUs.
Jon Jeffery or Steven Lohe
Jon Jeffery is currently working for Parker Aerospace as Director of Innovation and Marketing for the Hydraulic System Division in Kalamazoo, MI, and is the current Chairman for SAE A-6, the Aerospace Actuation, Control and Fluid Power Systems standards committee. Mr. Jeffery has been employed at Parker Aerospace for 20 years primarily in the development of aircraft hydraulic systems and associated hydraulic equipment. Mr. Jeffery started the hydraulic system product line at Parker in 1994 and has been involved with more than a dozen aircraft hydraulic system designs since that time. Prior to joining Parker, Mr. Jeffery worked at McDonnell Aircraft Company (now Boeing), St. Louis, Missouri for 12 years. He started as a hydraulic system design engineer during the early phase of the F/A-18 aircraft. He then spent 5 years working on hydraulic system research and development in the area of 8000 psi hydraulic system design, low energy consumption hydraulic techniques, enhanced dynamic stiffness for flight control actuators and variable pressure pumps. He published several technical papers on these subjects and was awarded a patent in 1986 for an energy recovery concept entitled “Flow Augmented Servovalve Technology (FAST) Actuator”. Mr. Jeffery later held the position of hydraulic team leader for the A-12 program and then as Unit Chief, Flight Controls & Hydraulic Systems for the F/A-18 programs. Mr. Jeffery received a Bachelor Degree in Mechanical Engineering from the University of Michigan and a Masters Degree in Engineering Management from Washington University in St. Louis, MO.
Steve Lohe has been in subsystems design at McDonnell Douglas/Boeing for thirty three years, mostly working hydraulic system design and analysis. He has worked hydraulics design for A-12, AV-8B, F/A-18E/F, F-15 Fly-by-Wire upgrade, MQ-25, T-7A and several proprietary programs. He has been responsible for the architecture and specification of several clean sheet hydraulic systems, including primary flight control actuation procurement. In addition, he had primary responsibility for the fuel system on X-45C and the environmental control systems on a proprietary proposal effort. He is currently Vice-Chair of the SAE A-6A2 Military panel. He received his B.S. in Mechanical Engineering from University of Missouri – Columbia, and his M.S. in Mechanical Engineering from Washington University.
