10 Megabit/sec Network Configuration Digital Time Division Command/Response Multiplex Data Bus

2013-04-29
HISTORICAL
AS5652
This SAE Aerospace Standard (AS) contains requirements for a digital time division command/response multiplex data bus, for use in systems integration that is functionally similar to MIL-STD-1553B with Notice 2 but with a star topology and some deleted functionality. Even with the use of this document, differences may exist between multiplex data buses in different system applications due to particular application requirements and the options allowed in this document. The system designer must recognize this fact and design the multiplex bus controller (BC) hardware and software to accommodate such differences. These designer selected options must exist to allow the necessary flexibility in the design of specific multiplex systems in order to provide for the control mechanism, architectural redundancy, degradation concept, and traffic patterns peculiar to the specific application requirements.

IEEE-1394b Interface Requirements for Military and Aerospace Vehicle Applications

2013-04-29
HISTORICAL
AS5643A
This SAE Aerospace Standard (AS) establishes the requirements for the use of IEEE-1394b as a data bus network in military and aerospace vehicles. It defines the concept of operations and information flow on the network. As discussed in 1.4, this specification contains extensions/restrictions to “off-the-shelf” IEEE-1394 standards, and assumes that the reader already has a working knowledge of IEEE-1394. This document is referred to as the “base” specification, containing the generic requirements that specify data bus characteristics, data formats and node operation. It is important to note that this specification is not stand-alone - several requirements provide only example implementations and delegate the actual implementation to be specified by the network architect/integrator for a particular vehicle application. This information is typically contained in a “network profile” slash sheet that is subservient to this base specification.

Validation Testing of Electric Fuel Pumps for Gasoline Fuel Injection Systems

2013-04-29
HISTORICAL
J1537_201304
This SAE Recommended Practice defines the minimum design verification testing required to verify the suitability of in-tank mounted electric motor driven fuel pumps used for pumping gasoline or gasoline blend fuels. Additional tests not specified in SAE J1537 will be required for frame mounted pump applications or pumps intended for use on aircraft, motorcycles, or marine equipment.

Mechanical and Material Requirements for Externally Threaded Fasteners

2013-04-29
HISTORICAL
J429_201304
This SAE Standard covers the mechanical and material requirements for inch-series steel bolts, screws, studs, screws for sems1, and U-bolts2 in sizes to 1-1/2 in. inclusive. The term “stud” as referred to herein applies to a cylindrical rod of moderate length threaded on either one or both ends or throughout its entire length. It does not apply to headed, collared, or similar products which are more closely characterized by requirements shown herein for bolts. The mechanical properties included in Table 1 were compiled at an ambient temperature of approximately 20 °C (68 °F). These properties are valid within a temperature range which depends upon the material grade used and thermal and mechanical processing.

Shot Peening Coverage Determination

2013-04-24
HISTORICAL
J2277_201304
This SAE recommended practice provides some procedure for determining shot peening coverage and relating coverage to part exposure to the media stream. Effectiveness of shot peening is directly dependent on coverage. Either incomplete or excessive coverage can be detrimental to fatigue strength and life.

CURRENT
ARP5624
This SAE Aerospace Recommended Practice (ARP) provides recommended definitions for terms commonly used in aircraft inflight icing system design and analysis, research, and operations. Some general thermodynamic terms are included that are frequently used in icing analysis, but this document is not meant to be an inclusive list of such terms.

Rotor Blade Electrothermal Ice Protection Design Considerations

2013-04-23
CURRENT
AIR1667A
This SAE Aerospace Information Report (AIR) identifies and summarizes the various factors that should be considered during design, development, certification, or testing of helicopter rotor blade ice protection systems. Although various concepts of ice protection are mentioned in this report, the text is limited generally to those factors associated with design and substantiation of cyclic electrothermal ice protection systems as applicable to the protection of helicopter rotor blades. Other systems are described briefly in Appendix A. Applications consider main rotor blades, conventional tail rotor blades, and other types of antitorque devices. The information contained in this report is also limited to the identification of factors that should be considered and why the factor is important. Specific design, analysis and test methodologies are not included. For additional information refer to the references listed in 2.1.

Information on Brake-By-Wire (BBW) Brake Control Systems

2013-04-22
HISTORICAL
AIR5372
A panel of the SAE A-5A Committee prepared this SAE Aerospace Information Report (AIR). The document describes the design approaches used for current applications of Brake-by-Wire (BBW) control systems that are used on commercial and military airplanes. The document also discusses the experience gained during service in the commercial and military environments, and covers system, ergonomic, hardware, and development aspects. The treatment includes the lessons that have been learned during application of the technology. Although there are a variety of approaches that have been used in the design of BBW systems, the main focus of this document is on systems that use the electro-hydraulic method of control. The overall range of implementations is briefly described in 2.3. Sections 3, 4, and 5 describe the electro-hydraulic method in detail.
