This document provides recommended practices for the design of tubing systems that are used for the transmission of liquid and gasses in fluid power systems for aerospace vehicles such as aircraft, missiles and boosters. The primary emphasis is given to recommended practices for line sizing, tube routing, supports and clamping, stress considerations and permissible defects, and provisions for flexure through the use of flexible hoses, coiled tubes, swivel joints, and expansion glands. The sections regarding tubing materials and fitting types are included for reference, but particular recommendations are purposely avoided since their selection is dependent upon the specific requirements of each particular vehicle system and many other factors.
1. SCOPE This Aerospace Recommended Practice (ARP) provides recommendations for the design and test requirements for hydraulic priority valves. The hydraulic priority valve is intended for use in a civil or a military aircraft hydraulic system with a rated system pressure up to 5000 psi (34500 kPa). 1.1 Purpose The recommended requirements contained in this document are compiled for inclusion in a Procurement Specification for a hydraulic priority valve. NOTE: The recommended requirements in this ARP should be reviewed by the Purchaser or the Contractor and only those requirements that are applicable for a specific application should be incorporated in the Procurement Specification. 1.2 Classification The hydraulic priority valve types covered by this ARP are: • The line-mounted type - a valve with standard fitting ends • The cartridge type - a cylindrical valve with O-ring glands for mounting in a manifold, for example
This Aerospace Recommended Practice (ARP) provides recommendations for the design and test requirements for hydraulic flow regulators (also known as flow control valves). The hydraulic flow regulator is intended for use in a civil or a military aircraft hydraulic system with a rated system pressure up to 5000 psi (34500 kPa).
This document is a compendium of recommended practices for the design of tubing systems for the transmission of liquid and gasses influid power systems for aerospace vehicles such as aircraft, missiles and boosters, and is considered applicable to the design of future space vehicles and other applications using aircraft technology. Primary emphasis is given to recommended practices for line sizing, tube routing, supports and clamping, stress considerations and permissible defects, and provisions for flexure through the use of flexible hoses, coiled tubes, swivel joints, and expansion glands. Fluid power systems are differentiated from the normal aircraft fuel and oil systems and the various fluid systems used for environmental control and air conditioning systems; however, the practices cited herein will in many cases be applicable to these other systems.
This SAE Aerospace Standard (AS) specifies the general requirements for hydraulic system reservoirs that are installed in commercial and military aircraft and helicopters and also in missile hydraulic systems.This document includes design, test (production and qualification) criteria for various types of reservoirs. Appendix A provides information on hydraulic fluid volume requirements and reservoir sizing.This document also provides a basis for the Procurement Specification to completely define individual reservoir requirements.

This SAE Aerospace Recommended Practice (ARP) addresses the design, installation, and testing of coiled tube assemblies using Ti-3Al-2.5V cold worked, stress relieved (CWSR) tubing per AMS4945. It specifically details five different configurations of coiled tubing. The configurations detailed herein should be compatible with pressure levels up to 8000 psi (55.2 MPa) upon completion of analysis for the actual stress and life requirement of the intended application. Formal qualification tests are recommended to verify satisfactory installation, clamping, and the life of each unique design. NOTE: For information on design of coiled tube assemblies using CRES steel tubing, see ARP584.

This SAE Aerospace Recommended Practice (ARP) is intended as a guide to aid in the specifying and testing of direct acting three way, two position, single and multiple coil, normally open and normally closed solenoid valves used for the pilot actuation of hydraulic control systems and the control of hydraulic components. The information presented should be useful in standardizing terminology, in specifying requirements and performance parameters, and in defining test methods. The recommendations do not restrict or attempt to define the internal design features of solenoid valves. Standard mechanical, electrical and fluid porting interfaces are recommended to provide commonalty, interchangeability, design flexibility and to be more affordable. In general, this recommended practice is directed toward solenoid valves for use in military and commercial flight control and hydraulic actuation systems.
