As part of the aircraft certification process, landing gear has to be certified against particular risks such as bird and tyre impact cases. According to international aviation regulations, it has to be demonstrated that the landing gear is designed to ensure the capability for continued safe flight and landing after bird impact or after tyre impact resulting from wheel or tyre failure. Structural parts such as the down-lock mechanism must be validated against these requirements since their structural integrity is essential to ensure landing gear down-locking for landing and subsequent on ground movement. Recently, MESSIER-BUGATTI-DOWTY has been involved in the development of explicit analysis in support of bird and tyre impact justification. A model of the down-lock mechanism has been developed and a full scale test has been set up in order to demonstrate the validity of the analysis. Two extensive test campaigns have been performed considering bird and tyre impact cases using highly instrumented components to record strains and displacements on impacted parts.

When performing catalyst modeling and parameter tuning it is desirable that the experimental data contain both transient and stationary points and can be generated over a short period of time. Here a method of creating such concentration transients for a full scale engine rig system is presented. The paper describes a valuable approach for changing the composition of engine exhaust gas going to a DOC (or potentially any other device) by conditioning the exhaust gas with an additional upstream DOC and/or SCR. By controlling the urea injection and the DOC bypass a wide range of exhaust compositions, not possible by only controlling the engine, could be achieved. This will improve the possibilities for parameter estimation for the modeling of the DOC. Important features of the resulting data include fast transients in concentrations with only small variations in temperature, CO concentrations with HC concentrations close to zero, and NO concentrations close to zero with significant NO2 concentration.

This SAE Recommended Practice applies to functions of motor vehicle signalling and marking lighting devices which use light emitting diodes (L.E.D.'s) as light sources. This report provides test methods, requirements, and guidelines applicable to the special characteristics of L.E.D. lighting devices. These are in addition to those required for devices designed with incandescent light sources. This report is intended to be a guide to standard practice and is subject to change to reflect additional experience and technical advances.

This SAE Aerospace Recommended Practice (ARP) provides best practices and guidance for creating an architecture for integrated vehicle health management systems. Where possible, this document will also provide references to tools to conduct architectural trades. Finally, this document will provide use cases to expose considerations and stakeholders to be included in these trades and utilization of an IVHM system (which may lead to new functional or non-functional requirements).

This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turboprop and turboshaft engines. This Aerospace Recommended Practice (ARP) shall apply to both dynamometer and propeller based testing. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine.

The SAE Standard covers normalized electric-resistance welded flash-controlled single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, beading, forming, and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path that would be caused by the ID weld bead or scarfed region. Assumption of risks when using this material for single flare applications to be defined by agreement between the producer and tube purchaser. This specification also covers SAE J356 Type-A tubing. The mechanical properties and performance requirements of standard SAE J356 and SAE J356 Type-A are the same. Therefore, the designated differences of Type-A tubing are not meant to imply that Type-A tubing is in anyway inferior to standard SAE J356. The Type-A designation is only meant to address the unique manufacturing differences of the small diameter, light wall sizes (typically 19.05 mm OD x 1.24 mm wall and smaller.)

This SAE Standard specifies requirements for vulcanized rubbers in sheet form for use as standards in characterizing the effect of test liquids and service fluids. The annexes contain the standard reference elastomer formulas. The property changes of the SRE in contact with the indicated fluid under specified test conditions are the responsibility of the user. See 7.3 and Table 1. This standard is not designed to provide formulations of elastomeric product compositions for actual service.

In May 1979 Martin Marietta Aerospace, Denver Division, completed a survey of missile hydraulic system cleanliness and contamination control procedures and practices as several aerospace companies. The intent of this survey was to gather and assemble the data from companies that manufacture missiles with hydraulic systems, similar to the Titan III System, from a contamination control standpoint. The survey concentrated on 15 subject areas of interest.

This specification establishes the requirements for etch inspection of bare high strength low alloy steel parts having tensile strength of 180 ksi (1241 MPa) and higher and of carburized parts to detect overheating caused by abusive machining or grinding in the heat treated condition, and to detect localized discontinuous carburization. This process is not applicable to surface hardened steels produced by nitriding or carbonitriding. This process may remove 0.0001 to 0.0005 inch (2.5 to 12.7 micrometers) from the surface of the part.
