This SAE Recommended Practice applies to the laboratory measurement of rolling resistance of pneumatic passenger car, light truck, and highway truck and bus tires. The procedure applies only to the steady-state operation of free-rolling tires at zero slip and inclination angles; it includes the following three basic methods:
This SAE Standard covers the measurement of radio frequency radiated emissions and immunity. Each part details the requirements for a specific type of electromagnetic compatibility (EMC) test and the applicable frequency range of the test method. The methods are applicable to a vehicle, boat, machine or device powered by an internal combustion engine or battery powered electric motor. Operation of all engines or motors (main and auxiliary) of a vehicle, boat, machine or device is included. All equipment normally operating when the vehicle, boat, machine or device is in operation is included. Operator controlled equipment is included or excluded as specified in the individual document parts. As a special case, CISPR 12 applies to battery powered floor finishing equipment, but robot carpet sweepers are excluded. By reference, IEC CISPR 12 and CISPR 25 are adopted as the standards for the measurement of vehicle emissions.
This Aerospace Recommended Practice provides guidance for designers and specifiers of aircraft exterior lighting. Typical causes of light degradation and methods of predicting performance degradation in the aircraft environment are given. Although the document considers only exterior lighting, many of the principles and methods discussed apply to interior or flight deck lighting as well.
(A) Propose Revision To Figure 1 To Show Port #1 Is Per AS4377 Style "S" In Both Cases and General Update (B) Propose revision to add conductive high purity aluminum coating per MIL-DTL-83488 for aluminum alloy fittings. The W code aluminum parts with new finish will be distinguished by new finish code V at the end of part number.
This SAE Aerospace Recommended Practice (ARP) provides technical recommendations for the lighting applications for Unmanned Aircraft Systems (UAS). The technical content of this ARP discusses the unique trade-offs that are necessary to maintain commonality to the U.S. Federal Aviation Regulations (FARs) for aerospace lighting. The recommendations set forth in this document are to aid in the design of Unmanned Aircraft (UA) lighting for the size of aircraft and operation for which the aircraft is intended. In addition, certain concepts of operation for which UASs are suited will require unique lighting solutions.
This document describes the major design drivers and considerations when designing a fuel system for a large commercial aircraft. It discusses the design at a system/aircraft level, and is not intended as a design manual for individual system components, though it does refer out to other SAE specifications where more detail on specific components and sub systems is given. It does include examples of a number of calculations associated with sizing of fuel systems, based on those given in NAV-AIR-06-5-504, as well as an appendix summarizing basic fluid mechanical equations which are key for fuel system design. It is acknowledged that most of these calculations would today be performed by modelling tools, rather than by hand, but it is considered important for the designer to understand the principles. It is intended that later issues of this document will include appendices which give specific considerations for military aircraft, smaller commercial aircraft, and rotorcraft.
The scope of this document is limited to the lubrication system of a conceptual high performance aircraft turbine engine. This document will not present or disclose any specific design data leading to the specific formulation of an advance engine lubricant or that of an advanced engine. General trends are presented based upon current literature and observations of lubricant/engine experience.
This SAE Standard establishes specifications for mid- and side-power take-off drives that will be helpful in designing implements. Design of the implement attaching means must be tailored to each tractor, depending on attaching points available and the exact location of the auxiliary shaft.
SAE CACRC has produced several standards, each representing the best-practice, recommended minimum training syllabus for the aforementioned target groups. The purpose of this document is to promote the use of these SAE standards, particularly for developing training programs for employee training, qualification in airlines and maintenance organizations, and as reference in regulatory guidance material. It summarizes, as a quick reference, the content of each training document and its relation to and interaction with other training documents. Thereby it allows users to select the appropriate training documents and syllabi to establish a comprehensive, sequential training program build-up customized to the specific needs of the aforementioned functions (see figure). This document does not intend to introduce new training content/syllabus.
This SAE Recommended Practice covers the design and application of a 120 VAC single phase engine based auxiliary power unit or GENSET. This document is intended to provide design direction for the single phase nominal 120 VAC as it interfaces within the truck architecture providing power to truck sleeper cab hotel loads so that they may operate with the main propulsion engine turned off.
1.1 Form This specification covers an aluminum alloy in the form of pre-alloyed powder. 1.2 Application This powder has been used typically in additive manufacturing of components requiring moderate strength at room temperature, but usage is not limited to such applications 1.3 Classification Powder size and maximum oxygen concentration is specified as follows: Class A: 20-63 µm, maximum oxygen concentration of 0.100% (1,000 ppm). Class B: 15-53 µm, maximum oxygen concentration of 0.150% (1,500 ppm). Class C: 10-90 µm, maximum oxygen concentration of 0.150% (1,500 ppm). Class D: 20-90 µm, maximum oxygen concentration of 0.100% (1,000 ppm).
