This Aerospace Recommended Practice (ARP) provides guidance on methods for system level pump ripple and pulsation testing. Covered are pump testing versus system pulsation testing, test conditions, instrumentation and data collection, data reduction and analysis, and resolution of issues identified during testing.

Much of the available long-term storage test data has been reviewed and topically separated to enable the independent discussion of storage effects on fluids, seals, hydraulic components, and hydraulic systems. Comments are made in Section 4 concerning the applicability of the test results and regarding design practices for storability. Conclusions are drawn in Section 5 regarding inactive storage of hydraulic systems for at least a 7 year period.

This SAE Aerospace Information Report (AIR) provides design data reliability information relative to the long-term storage of gas containers or pressure vessels charged with nitrogen or helium at pressures ranging from 6000 to 12 000 psi. The gas containers are cylindrical, spherical, or toroidal in shape. Internal volumes range up to 1385 in3. Applications for this type cold gas actuation system include tactical missiles, guided projectiles, and smart bombs. A typical system is described.

This specification covers the design and installation requirements for Types I and II military aircraft hydraulic systems.

This SAE Aerospace Standard (AS) provides general requirements for components that are used in military aircraft and missile hydraulic systems.

This specification covers the general requirements that are common to most hydraulic components (see 6.2), used in aeronautical hydraulic systems (see 6.1).

This report supplies data on various survivability design approaches and techniques to provide a broad frame of reference for future fluid power designers. Before the designer embarks on the overall system design, a comprehensive understanding of the total hostile environment in which the air vehicle is to operate is mandatory. The overall approach is heavily dependent upon the level of threat, small arms versus medium, or heavy caliber antiaircraft projectiles, missile, single or multiple hit survivability and the projected angle of fire. Overall aircraft stability is a factor which dictates recovery speed from any given failure and limits the magnitude of transient disturbances in the control system. The designer should strive to achieve at a minimum a system which allows high performance type aircraft to obtain a quasi-stable period following total control loss to allow safe ejection of the air crew.

The purpose of this document is to outline and publish the criteria applicable to design and installation for types I and II, classes 4000 and 5000 psi aircraft hydraulic systems.

Systems shall be classified in terms of type, category and class.

This SAE Aerospace Recommended Practice (ARP) provides processes for achieving the required cleanliness standards during the fabrication, assembly, and functional test of aircraft hydraulic systems. It covers exclusion and removal of solid and liquid contaminants from tubing during manufacture and final assembly, flushing of the installed system, and final checks to ensure cleanliness requirements are met.

This SAE Aerospace Recommended Practice (ARP) establishes the processes to achieve and maintain the required cleanliness levels in flight vehicle hydraulic systems during fabrication, assembly and pre-flight functional tests. This recommended practice covers exclusion and removal primarily of solid contaminants that occur or are created during these successive steps. The flushing procedure for installed tubing is detailed. This ARP does not address contamination levels of hydraulic fluids as purchased, operation and maintenance of ground carts, details of component cleanliness or of contamination measurement. This ARP applies to military aircraft and helicopters designed to AS5440, commercial aircraft hydraulic systems designed to ARP4752 and commercial helicopter hydraulic systems designed to ARP4925.
