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 – 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 – These services, when queried, return instantaneous sensor data. Three services are defined that return respectively joint positions, joint velocities, and joint

The purpose and intent of Subcommittee E-33E’s 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

Testing is specified during steady state (non-transient) operation only, in a ground level test bed. Included are recommended test setup, test procedures, techniques for sampling ambient air and bleed air, and one or more specific analytical methodologies for each of the suggested bleed air contaminant marker compounds at quantification levels, given practical constraints

This SAE Standard defines and provides a means for the control of colors employed in motor vehicle external lighting equipment, including lamps and reflex reflectors. The document applies to the overall effective color of light emitted by the device in any given direction, and not to the color of the light from a small area of the lens. It does not apply to pilot, indicator, or tell-tale lights
This SAE Recommended Practice establishes test procedures, test conditions, environment, and instrumentation for determining the exhaust sound pressure levels of stationary motorcycles. These are based on a comprehensive study of a wide variety of on-highway motorcycles, and therefore are intended to be applied to on-highway motorcycles. For off-highway motorcycles, SAE J1287 continues to be the recommended practice

Included herein are the detailed general and dimensional specifications applicable to hi-head finished hex bolts. All general specifications and dimensions not shown shall conform to those applicable to finished hex bolts in Table 4 of SAE J104. Hi-head finished hex bolts arc primarily intended for use in the heavy construction and industrial equipment industry. The increase in head height over that of the finished hex bolt assures good wrenchability where frequent servicing is necessary, where high torquing is a requirement, or where wear on the bolt head is a problem

This SAE Standard establishes terminology and the content of commercial literature specifications for self-propelled crawler and wheeled material handlers, pedestal mounted material handlers and their equipment as defined in 3.1. Illustrations used here are not intended to include all existing commercial machines or to be exactly descriptive of any particular machine. They have been provided to describe the principles to be used in applying this document. (Material handlers share many design characteristics with hydraulic excavators and log loaders; primarily 360 degree continuous rotation of the upperstructure relative to the undercarriage or mounting. They differ in their operating application. Material handlers are used for the handling of scrap material and normally utilize grapples or magnets. Hydraulic excavators are used for the excavation of earth, gravel and other loose material utilizing a bucket. Log loaders are used for the handling of logs and trees and normally utilize

IEEE-1394b, Interface Requirements for Military and Aerospace Vehicle Applications, establishes the requirements for the use of IEEE Std 1394™-2008 as a data bus network in military and aerospace vehicles. The portion of IEEE Std 1394™-2008 standard used by AS5643 is referred to as IEEE-1394 Beta (formerly referred to as IEEE-1394b.) 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 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 designed to be stand-alone; several requirements leave the details to the implementations and delegate the actual implementation to be specified by the network architect/integrator for a
