This specification covers environment-resisting, quick disconnect, EMI/RFI shielded and non-shielded umbilical, electric connectors and adapter assemblies with removable crimp or nonremovable solder-type contacts and accessories. Connectors are rated for operation from -55 Ā°C (-67 Ā°F) to 200 Ā°C (392 Ā°F). Adapter assemblies are rated for operation from -55 Ā°C (-67 Ā°F) to 125 Ā°C (257 Ā°F). The upper temperature is the maximum internal hot spot temperature resulting from any combination of electrical load and ambient temperature

The information contained in this document is based on line experience with current systems. It should be used as a basis for ongoing research and development including the human factors aspects of future flight management systems and their interaction with the ATC environment
This SAE Aerospace Information Report (AIR) describes the characteristics and effects of using no-break power transfer (NBPT) methods when switching between auxiliary-power unit (APU) and ground-power unit (GPU). The GPU may be: a Point-of-use solid-state frequency converter, engine-generator, or motor-generator b Central system powered by motor-generator or solid-state frequency converter
This Aerospace Information Report (AIR) establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AMS 5561 steel, AMS 4944 titanium and MIL-T-7081 aluminum alloy, mounted as free-free resonant beams. Of particular advantage are the inherent simplicity of test setup, minimum restraint from a test fixture, low power requirements, short test duration, and ease of varying stress level
The environmental factors of prime importance in the transport of animals in aircraft are air temperature, humidity and carbon dioxide concentration, and of course space (or volume) limitations. Secondary factors are air velocity, noise, lighting, etc. Pressure is not addressed herein as pressure levels and rates of change are totally dictated by human occupancy requirements. Some basic governmental documents, such as References 1, 2 and 3, define overall requirements for animal transportation, but with very limited data on environmental requirements. Reference 4 gives some airplane characteristics measured during animal transportation from the USA to foreign destinations. Temperature and humidity profiles are indicative of airplane characteristics. This report presents information on the temperature, humidity, ventilation, and carbon dioxide limitations and the metabolic heat release rates for animals which will allow the determination of the environment required by the animals
This SAE Aerospace Recommended Practice (ARP) applies to airline trailer equipment with four wheel running gear pulled and steered through an integral tow bar, for use on airport ramps and other airport areas for transporting baggage, freight, and other materials. This ARP can apply to any airline/airport trailer chassis regardless of its equipment; the trailer bed can be designed to carry either bulk baggage/cargo, or a cargo unit load device by means of a rollerized conveyor system, or a piece of aircraft servicing equipment (e.g., ground power unit, air start unit, etc
This SAE Aerospace Recommended Practice (ARP) provides guidance for the presentation of gas turbine engine transient performance models with the capacity to be implemented as computer programs operating in real time and is intended to complement AS681. Such models will be used in those applications where a transient program must interface with physical systems. These applications are characterized by the requirement for real time transient response. These models require attention to unique characteristics that are beyond the scope of AS681. This document is intended to facilitate the development of mathematical models and the coordination of their requirements with the user. It will not unduly restrict the modeling methodology used by the supplier. The objective of this document is to define a recommended practice for the delivery of mathematical models intended for real time use. Models used in this application may also be contained in deliverable computer programs covered by AS681
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. This document is also intended to act as a guide for improving uncertainty analyses in a broad spectrum of related industries
This document defines a set of standard application layer interfaces called JAUS Manipulator Services. JAUS Services provide the means for software entities in an unmanned system or system of unmanned systems to communicate and coordinate their activities. The Manipulator Services represent platform-independent capabilities commonly found across domains and types of unmanned systems. At present, twenty-five (25) services are defined in this document. These services are categorized as: Low Level Manipulator Control Services ā The one service in this category allows for low-level command of the manipulator joint actuation efforts. This is an open-loop command that could be used in a simple tele-operation scenario. The service in this category is listed as follows: Primitive Manipulator Service Manipulator Sensor Services ā These services, when queried, return instantaneous sensor data. Three services are defined that return respectively joint positions, joint velocities, and joint
The external threaded fastener protrusion shall be defined as the external threads including the chamfer which extend through the top surface of the nut, see Figure 1
The purpose and intent of Subcommittee E-33Eās effort, the reporting objectives, and the limitations inherent in the reported findings and recommendations are reviewed since these factors are the basis of the information contained in this document. SAE E-33E Subcommittee was formed to assess the level of industry experience that exists in the area of thrust determination during aircraft time-variant operating conditions. A prime objective was to provide a center for gathering expertise and to be a forum for the exchange of ideas and viewpoints. The committee recognized that a practice for the rigorous treatment of time-dependent thrust did not exist and that several critical aspects of its accounting would need to be investigated. The specific objectives of this document are: a To examine aircraft and engine operating conditions under which the quasi-steady thrust assumption is valid. b To determine the extent to which time-dependent (nonstationary) force accounting for engine net
