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.

In efforts to increase the accuracy and reliability of altimetry, speed measurement and other aspects of air data, a great deal of attention and money have been expended on new and refined pressure transducing and computing systems and on the standards by which they are calibrated. So much progress has been made in this that the limiting factor is, or may soon be, the sensing and transmitting in the aircraft of the pressures to be transduced. Until the appearance of References 1-13 and 18 there was little guidance available on the maintenance of pitot and static systems. This report presents what information is available, suggests limits, and lists the principal original papers on the subject.

This SAE Aerospace Information Report (AIR) defines a Generic Aircraft-Store Interface Framework (GASIF). This is a common framework for modeling and specifying aircraft-store logical interfaces. GASIF complies with the OSI Basic Reference Model (ITU-T Rec. X.200 | ISO/IEC 7498-1) in that it describes operations and mechanisms which are assignable to layers as specified in the OSI Basic Reference Model. This AIR provides a mapping of the Interface Standard for Aircraft-store Electrical Interconnection System (AEIS), MIL-STD-1760, in Appendix C.

The purpose of this document is to establish the requirements for sensor/video interconnect subsystems. These requirements have been driven predominantly, but not exclusively, by aerospace-type military platforms and commercial aircraft. These requirements are intended to be used as the criteria to establish a sensor/video interconnection standard that will foster the development of common hardware to simplify the total interconnectivity of future avionics platforms.

This section defines the scope of the document, provides a brief history of the Pi-Bus, discusses key features of the Pi-Bus, and provides an overview of the operation of the Pi-Bus. This document is a handbook intended to accompany AS4710 Pi-Bus standard. The purpose of this document is to provide information to aid users of the Pi-Bus, whether they be implementors of Pi-Bus controllers, architects of systems considering using the Pi-Bus, or programmers who must develop applications in a system which uses the Pi-Bus as the backplane communications bus. This document also provides rationale for many of the Pi-Bus requirements as defined in AS4710 and a discussion of potential enhancements that are being considered for the Pi-Bus.

This information report provides a review of liquid drop and ice crystal particle sizing instruments used for facility based icing research and in-flight testing commonly used for aircraft certification icing envelopes. This report will provide an overview of the theory of operation of these instruments and practical considerations when using them for cloud characterization. Methods in use for data reduction (including combining output from multiple probes) as well as potential error sources are provided for information. Measurement methods from prior revisions of this AIR that are no longer commonly used (e.g. oil slides and rotating cylinders) will be retained for reference. This document does not include other icing cloud measurements such as liquid or total water contents, or measurement of other types of phenomena such as snow, sleet or hail.

The original purpose of this document was to establish interface requirements for modular avionics backplanes to be prototyped up to 1995. The document was issued as ARD50011 in September 1992. It is being reissued as an SAE Aerospace Information Report (AIR) in order to: Preserve the requirements for more than 2 years Support design of retrofits and avionics systems to be fielded in the years 1995 to 2000 Provide a baseline for updating the requirements of future integrated systems These requirements were and are intended to promote standardization of modular avionic backplane interfaces. These requirements have been driven predominantly, but not exclusively, by aerospace type military platforms.

This SAE Aerospace Information Report (AIR) has been prepared to provide information regarding options for optical control of fluid power actuation devices. It is not intended to establish standards for optical fluid power control, but rather is intended to provide a baseline or foundation from which standards can be developed. It presents and discusses approaches for command and communication with the actuation device via electro-optic means. The development of standards will require industry wide participation and cooperation to ensure interface commonality, reliability, and early reduction to practice. To facilitate such participation, this document provides potential users of the technology a balanced consensus on its present state of development, the prospects for demonstration of production readiness, and a discussion of problem areas within this technology.

Gas compressors (air and other compressible fluids) have been used sporadically since the 1940's for various utility functions in aerospace applications. They have been used to provide power to gun purge and drive systems, engine or APU starters (recharge accumulators), reservoir pressurization, cockpit pressurization, braking systems, canopy seals, engine control devices, landing gear activation, and boosted flight controls (see Table 1). In current state-of-the-art aircraft, most pneumatic system power is extracted from a stage of compression in the turbo-jet engine. As more and more demands are put on new generation engines for fuel economy and performance there is an increasing need for a new source of pneumatic power. This document is intended to describe current state-of-the-art technology in compressors, define the limitations, discuss enhancements needed and attempt to predict the needs of the future.

This document discusses, in broad general terms, typical present instrumentation practice for post-overhaul gas turbine engine testing. Production engine testing and engine development work are outside the scope of this document as they will typically use many more channels of instrumentation, and in most cases will have requirements for measurements that are never made in post-overhaul testing, such as fan airflow measurements, or strain measurements on compressor blades. The specifications for each parameter to be measured, in terms of measurement range and measurement accuracy, are established by the engine manufacturers. Each test cell instrument system should meet or exceed those requirements. Furthermore, each instrument system should be recalibrated regularly, to ensure that it is still performing correctly.

This information report presents a preliminary discussion of liquid propellant gas generation (LPGG) systems. A LPGG system, as used herein, is defined as a system which stores a liquid propellant and, on command, discharges and converts the liquid propellant to a gas. The LPGG system can interface with a gas-to-mechanical energy conversion device to make up an auxiliary power system. Figure 1 shows a block diagram of LPGG system components which include a propellant tank, propellant expulsion system, propellant control and a decomposition (or combustion) chamber. The purpose of this report is to provide general information on the variety of components and system arrangements which can be considered in LPGG design, summarize advantages and disadvantages of various approaches and provide basic sizing methods suitable for initial tradeoff purposes.
