GEIASTD0005_3A
This document defines: A default method for those companies that require a pre-defined approach and A protocol for those companies that wish to develop their own test methods. The default method (Section 4 of the document) is intended for use by electronic equipment manufacturers, repair facilities, or programs which, for a variety of reasons, may be unable to develop methods specific to their own products and applications. It is to be used when little or no other information is available to define, conduct, and interpret results from reliability, qualification, or other tests for electronic equipment containing Pb-free solder. The default method is intended to be conservative, i.e., it is biased toward minimizing the risk to users of AHP electronic equipment.

A life support system (LSS) is usually defined as a system that provides elements necessary for maintaining human life and health in the state required for performing a prescribed mission. The LSS, depending upon specific design requirements, will provide pressure, temperature, and composition of local atmosphere, food, and water. It may or may not collect, dispose, or reprocess wastes such as carbon dioxide, water vapor, urine, and feces. It can be seen from the preceding definition that LSS requirements may differ widely, depending on the mission specified, such as operation in Earth orbit or lunar mission. In all cases the time of operation is an important design factor. An LSS is sometimes briefly defined as a system providing atmospheric control and water, waste, and thermal management. The major subsystems required to accomplish the general functions mentioned above are: Breathing and pressurization gas storage system. Temperature and humidity control system.

J1574/2_201210
This SAE Information Report presents the background and rationale for SAE J1574-1. The motor vehicle industry is working toward a more complete understanding of the factors affecting the motions of vehicles on the roadway, by using a variety of techniques that predict responses to road and operator inputs. The capability to predict responses is desirable so that vehicles can be designed for optimum safety and utility. In addition to the force and moment properties of the pneumatic tires, a number of vehicle and suspension parameters affect the response of the vehicle; these include weight, center-of-gravity location, moments of inertia, suspension ride and roll rates, suspension kinematic and compliance properties, and shock absorber characteristics. These parameters must be quantified in order to predict vehicle responses. Measurement of most of these parameters will be limited to determining their values in the linear range for use in directional control simulations.

J1574/1_201210
The parameters measured according to this SAE Recommended Practice will generally be used in simulating directional control performance in the linear range. (The “linear range” is the steady-state lateral acceleration below which steering wheel angle can generally be considered to be linearly related to lateral acceleration.) But they may be used for certain other simulations (such as primary ride motions), vehicle and suspension characterization and comparison, suspension development and optimization, and processing of road test data. This document is intended to apply to passenger cars, light trucks, and on-highway recreational and commercial vehicles, both non-articulated and articulated. Measurement techniques are intended to apply to these vehicles, with alterations primarily in the scale of facilities required.

This SAE Aerospace Recommended Practice (ARP) defines a means of assessing the credibility of computer models of aircraft seating systems used to simulate dynamic impact conditions set forth in Federal Regulations 14 CFR Part 23.562, 25.562, 27.562, and 29.562. The ARP is applicable to lumped mass and detailed finite element seat models. This includes specifications and performance criteria for aviation specific virtual anthropomorphic test devices (v-ATDs). A methodology to evaluate the degree of correlation between a seat model and dynamic impact tests is recommended. This ARP also provides testing and modeling best practices specific to support the implementation of analytical models of aircraft seat systems. Supporting information within this document includes procedures for the quantitative comparison of test and simulation results, as well as test reports for data generated to support the development of v-ATDs and a sample report.

ARP6407
This SAE Aerospace Recommended Practice (ARP) provides guidelines for the design of Integrated Vehicle Health Management (IVHM) systems. This guidance is technology-independent; the principles are therefore generally applicable to the majority of potential IVHM design scenarios, including “clean sheet” system design, where IVHM is considered as a primary design consideration and the retrofit of existing systems with IVHM capability, where the design process leverages and supports existing system elements. In either case, the document will provide guidance on the design considerations for an IVHM system throughout the analysis, concept development, and synthesis stages of the IVHM Design process and provide discussion for the users’ consideration on the trades, metrics, and lifecycle impacts of IVHM design decisions.

This paper presents guidelines for development of a procedure for external software loading of an electronic engine control (EEC) for a commercial application, on-wing or in a qualified service shop. This paper makes the following assumptions: The EEC is designed to accept external software loading. The EEC is certified as part of an engine. The support equipment is qualified in accordance with procedures set forth by the engine (and aircraft, if necessary) certifying authority if the EEC cannot detect an integrity violation of the loaded program. The software to be loaded has been approved by the engine and aircraft certifying authorities. One or more configurations of EEC hardware has been identified for each version of software which is to be loaded in the EEC. It is appropriate to use these guidelines in the initial development phase, although the certification issues would not be applicable.

The primary objective of this document is to describe the systematic and random measurement uncertainties which may be expected when testing gas turbine engines in a range of different test facilities. The documentation covers a "traditional" method for estimating pretest uncertainties and a "new" method for computing and comparing posttest uncertainties. To determine these posttest uncertainties, data generated during the AGARD Uniform Engine Test Program (UETP) were analyzed and compared to the pretest estimates. The proposed procedure provides a mechanism for determining the expected accuracy of test results obtained from facilities which were not previously cross calibrated. Furthermore, the method can be used to assist in making cost-effective management decisions on the level of validation/cross calibration necessary when bringing a test facility on line.

The scope of this information report applies to the steady state measurement of direct mass fuel flow in gas turbine engine test cells. A measurement accuracy, and hence uncertainty of between ±0.1 to ±0.2% of value is believed to be achievable for liquid flow applications with some meter models/installations. Whilst capable of general transient measurement in 50 to 100 Hz region, this type of fuel meter is not capable of rapid transient measurement (in 100 to 250 Hz region). It is also not currently considered suitable for "in flight" fuel flow measurement.
