The exponential increase in the number of aircraft and air travelers has triggered new innovations aimed to make airline services more reliable and consumer friendly. Quick and efficient maintenance actions with minimum downtime are the need of the hour. Another major challenge is ensuring maintenance personnel are trained effectively; technology like augmented reality and Virtual Maintenance Trainers (VMTs) may provide safe and efficient training in lieu of live, instructor-led arrangements. And while traditional User/Maintenance Manuals provide useful information when dealing with simple machines, when dealing with complex systems of systems and miniaturized technologies, like unmanned aerial vehicles (UAVs), new technologies like augmented reality can rapidly and effectively support the maintenance operations.
The purpose of this SAE Recommended Practice is to promote the highest professional and personal conduct of practitioners in the fields of accident investigation and reconstruction. It encourages the continuous application of high ethical principles to one’s own endeavors. It also encourages the application of these same principles to others associated with accident investigation and reconstruction.
The following requirements and test information can be used to obtain reasonable quality and uniformity for bumper jacks. For this specification, a fully loaded vehicle includes curb weight, optional equipment, weight at 150 lb each for specified number of passengers, and a 150 lb load in the trunk. Vehicles with a gvw rating will be loaded to the maximum specified gvw.
This SAE Parts Standard provides dimensional and quality assurance requirements for studs in the following configurations in standard materials used for ship system applications: a. Continuous thread studs in UNRC and 8UNR series in the following threads and diameters: - UNRC threads (0.190 through 4 inches) - UNRF threads (0.190 through 1-1/2 inches) - 8UNR threads (1-1/8 through 4 inches) b. Double end studs (clamping type) where both ends are of the same thread length in the following threads and diameters: - UNRC threads (1/4 through 4 inches) - UNRF threads (1/4 through 1-1/2 inches) - 8UNR threads (1-1/8 through 4 inches) c.
This SAE Parts Standard provides dimensional and quality assurance requirements for 1/4 through 2 in sizes of studs in the following configurations in standard materials used for ship system applications: a. Continuous thread studs in UNRC and 8UNR series. b. Double end studs (clamping type) where both ends are of the same thread series (UNRC or 8UN). Also called bolt-studs. (These are suitable for mating with nuts or the set end may be installed with anaerobic thread locking compound.) c. Double end studs (interference thread type) with the nut end having UNRC or 8UNR series thread and where the tap end has NC 5 HFS interference fit thread forms. Also called a tap end stud. A complete metric companion to this document is provided in SAE J2271M, therefore no metric equivalents are presented. These studs are primarily or use in ship systems and equipment.
This SAE Recommended Practice is intended to serve as a reference for the amount of torque that a Power Take-Off can induce on the transmission mounting pad. This document will apply to six-bolt, eight-bolt, and rear mounted power take-offs.
This standard covers the identification, classification, and chemical composition of tool and die steels for use by engineers, metallurgists, tool designers, tool room supervisors, heat treaters, and tool makers.
