This document provides a description of a process for development of fly-by-wire actuation systems. Included are (1) the development of requirements for the servo-actuator hardware and the electronics hardware and software, (2) actuator and servo-electronics interface definitions and, (3) the required communications and interactions between the servo-actuator and the servo-electronics designers.
This SAE Standard provides general design performance requirements and related test procedures for composite lighting unit assemblies, other than signaling and marking devices, used on construction and industrial machines as defined in SAE J1116. Purpose To provide general guidelines and design parameters for lighting assemblies used on construction and industrial machinery.
This SAE Recommended Practice establishes the instrumentation, test site, and test procedure for determining the maximum exterior sound level for snowmobiles. Sound propagation is directly related to the ground cover and provides the largest variation to the measured result. A correction factor is introduced to improve year round test repeatability of the results on grass surfaces by correcting their spectrum to be similar to snow covered spectra. Measured sound pressure levels are also highly dependent on the degree of track slip present when performing the vehicle acceleration. Operators should attempt to limit track slip as much as possible while maintaining the requirements described in 5.1.1.
This specification covers one type of a nonmelting, heat stable silicone compound for use in high tension electrical connections, ignition systems and electronics equipment; for application to unpainted mating threaded or non-threaded surfaces, and as a lubricant for components fabricated from rubber. This compound is effective in the temperature range from -54°C (-65°F) to +204°C (+400°F) for extended periods and to 260°C (500°F) for short periods. This compound is identified by NATO symbol S-736 (see 6.5).
To establish criteria for acceptability of discontinuities as revealed by inspection by magnetic particle, fluorescent penetrant, or contrast dye penetrant inspection. Criteria for acceptability of discontinuities cited herein revealed by other methods required by applicable part specification shall be as specified in applicable part specification. This specification is primarily intended to cover standard parts such as pins, nuts and fittings. It may be applied to any item which must meet the specified requirements except that the requirements of AS 1177 apply to bolts, screws and studs.
This recommended practice provides the dimensional data for the diameters of surfaces that interface with the following tee head bolt series: AS 3232 thru AS 3235, MS 9397 thru MS 9402 and MS 9432 thru MS 9437, or other parts with compatible dimensions.
Consideration for the damaging effects to aircraft from the failure of wheels and tires should be evaluated. This document discusses the types of problems in-service aircraft have experienced and methodology in place to assist the designers when evaluating threats for new aircraft design. The purpose of this document is to provide a history of in-service problems, provide a historical summary of the design improvements made to wheels and tires during the past 40 years and to offer methodology which has been used to help designers assess the threat to ensure the functionality of systems and equipment located in and around the landing gear and in wheel wells.
