This SAE Aerospace Recommended Practice (ARP) establishes the factors which should be considered in the design and installation of a hydraulic system that is fitted to a commercial transport aircraft.

This SAE Aerospace Recommended Practice (ARP) establishes the factors which should be considered in the design and installation of a commercial transport rotorcraft hydraulic system, including the applicable airworthiness regulations that affect the hydraulic system.This ARP also provides information and guidelines on the many factors that arise in the design process to provide cost effectiveness, reliability, maintainability and accepted design and installation practices. The changes to ARP4925 at Revision B include: aTechnical changes to reflect the latest hydraulic system technologies. bEditorial changes including updating the references and improving the readability of the document.

Commercial Aircraft Hydraulic Systems: Shanghai Jiao Tong University Press Aerospace Series focuses on the operational principles and design technology of aircraft hydraulic systems, including the hydraulic power supply and actuation system and describing 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 that describes the whole lifecycle of integrated design, analysis, and assessment methods and technologies, enabling readers to tackle challenging high-pressure and high-power hydraulic system problems in university research and industrial contexts. Commercial Aircraft Hydraulic Systems is the latest in a series published by the Shanghai Jiao Tong University Press Aerospace Series that covers 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. 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. - Presents the first book to describe the interface between the hydraulic system and the flight control system in commercial aircraft - Focuses on the operational principles and design technology of aircraft hydraulic systems, including the hydraulic power supply and actuation system - Includes the most advanced methods and technologies of hydraulic systems - Describes the interaction between hydraulic systems and other disciplines

This SAE Aerospace Information Report (AIR) describes hydraulic system design and installation to minimize the effects of lightning, especially when the aircraft structure is composite. Techniques for effective electrical bonding, hydraulic system lightning protection, and lightning protection verification techniques are discussed. There is a need to address the effects of lightning on hydraulic systems in aircraft, especially where there is a significant use of composite materials in the aircraft structure. This is due to the potential structural damage and component failures that could occur. This document addresses this need.

The book addresses hydraulic system operation and design from an aerospace perspective. The book covers issues of fluids and fluid flow, component operation and system design. Component sizing methods, mathematical relationships and modeling equations are presented for each component. A methodology for system level modeling and simulation is also presented. Numerous examples and worked sample problems are included. Version 2 fixes some formatting and typo issues, and adds some technical content, and clarifies technical content in a few areas.

This SAE Aerospace Information Report (AIR) contains regulatory and guidance information related to transport airplane hydraulic systems. It contains certain Civil Air Regulations (CAR) and Federal Aviation Regulations (formerly referred to as FARs) from Title 14 Code of Federal Regulations (CFR) in their current version as well as the historical versions. This gives the reader an ability to assemble certain CAR/CFR parts as they existed at any date in the past (referred to as a Regulatory Basis). A certain amount of preamble explanatory material is included, which led to the regulatory rule changes (Amendments to the CFR). This document has been determined to contain interesting History and associated details still relevant as is for the industry. It is proposed by the committee to stabilize.
