Commercial Aircraft Hydraulic Systems focuses on the operational principles and design technology of aircraft hydraulic systems, including the hydraulic power supply system and actuation system. . The book also describes some new types of structures and components such as the 2H/2E structure design method and the use of electro hydrostatic actuators (EHAs). Based on the commercial aircraft hydraulic system, this is the first textbook book describing the whole life cycle of integrated design, analysis, and assessment methods and technologies, enabling readers to tackle challenging high-pressure and high-power hydraulic system problems in university researchand industrial R&D contexts. Commercial Aircraft Hydraulic Systems is the latest in a series published by The Shanghai Jiao Tong University Press Aerospace Series, covering the latest advances in research and development in aerospace. Its scope includes theoretical studies, design methods, and real-world implementations and applications. The readership for the series is broad, reflecting the wide range of aerospace interest and application, but focuses on engineering. Titles within the series include: Reliability Analysis of Dynamic Systems, Wake Vortex Control, Aeroacoustics: Fundamentals and Applications in Aeropropulsion Systems, Computational Intelligence in Aerospace Engineering, and Unsteady Flow and Aeroelasticity in Turbomachinery.
