This document establishes age limits for acceptance of hose and hose assemblies containing elastomeric materials for use in aircraft, space vehicles, missiles and component assemblies thereof at time of delivery to the contractor, procuring activity, or contracting officer. This document does not establish limitations on storage times for military activities nor operating life.
This report summarizes data and background relative to age control of specific classes of those nitrile type synthetic elastomers used in sealing devices which are resistant to petroleum base hydraulic fluids, lubricating oils and aircraft fuels. This includes, but is not limited to, those nitrile (NBR or BUNA-N) elastomers specifically covered by Section I of MIL-STD-1523.
This SAE Aerospace Standard provides standardized gland (groove) design criteria and dimensions for elastomeric seal glands for static and dynamic applications. The glands have been specifically designed for applications using SAE AS568 size O-rings at pressures exceeding 1500 psi utilizing one or two anti-extrusion (backup) rings and applications at pressures under 1500 psi without backup rings. The glands have been sized to provide sufficient squeeze for effective sealing while at the same time limiting squeeze to allow satisfactory operation in dynamic applications. While specifically designed for standard size O-rings, these glands are also to be used with other elastomeric seals.
This Aerospace Information Report (AIR) contains technical information on aerospace hydraulic and actuation technologies lessons learned. The lessons learned were prepared by system designers and hydraulic engineers from the aerospace industry and government services as part of SAE Committee A-6, Aerospace Fluid Power, Actuation, and Control Technologies, and were presented at three Lessons Learned Symposia in 1989 and 1990 held during A-6 Committee meetings. The technical topics represent many years of design experience in hydraulics and actuation, which it is felt is a resource for learning that should be documented and made available to current and future aerospace hydraulic engineers and designers. The document is organized into two sections; systems and components, with further categories within the components section.
This SAE Aerospace Information Report (AIR) lists military and industry specifications, standards, recommended practices and information reports used in the design of aerospace hydraulic and pneumatic components and systems. It is intended as a supplement to specifications ARP4752, MIL-H-5440, and MIL-P-5518. Only those hardware standards specifically applicable to hydraulic or pneumatic components or systems are listed in this document.
This report lists military and industry specifications and standards which are used in aerospace hydraulic and pneumatic systems. It is intended as a supplement to specifications MIL-H-5440 and MIL-P-5518. Only those hardware standards which have been specifically designed for hydraulic or pneumatic use are listed. Revisions and amendments which are current for these specifications and standards are not listed. Order of procedure for the selection of specifications and standards is covered by MIL-STD-970.
This Aerospace Recommended Practice includes the following areas: basis for system requirements; selection of materials coupled with hazards and safety; configuration of design; system operation; and evalua tion testing.
