This SAE Standard establishes the requirements for nondispersant, mineral lubricating oils to be used in four-stroke cycle piston aircraft engines. This document covers the same lubricating oil requirements as the former military specification MIL-L-6082. Users should consult their airframe or engine manufacturers manuals for the latest listing of acceptable lubricants.
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.
This SAE Metric Aerospace Standard (MA) establishes the requirements for fluid fittings that combine both weld fitting end and 24° cone flareless fitting end connections for use in all types of metric fluid systems.
The CAESAR (Civilian American and European Surface Anthropometry Resource) research project was a landmark study that has brought us the most current data on civilian body measurements. This final report details the methodology of the study and the data gathering process. It gives detailed explanation on the survey instruments used, how the study was conducted and who was included to achieve a valid demographic sampling. The product provides a wealth of information on this large scale and statistically valid research project.
Electronic parts are used throughout industry to run everyday products, such as cell phones, and also highly technical products, such as aircraft, missiles, and spacecraft. Unlike cell phones, which are often replaced every year, the highly technical products may remain in service from 20 to more than 80 years. But what happens if the original electronic part, with a life cycle of 18 months, is no longer available? Some manufacturers have discovered that they have unwittingly purchased counterfeit ones. Counterfeit Electronic Parts and Their Impact on Supply Chains examines how these items are negatively affecting the aviation, spacecraft, and defense sectors and what can be done about it.
The electric vehicle industry - land, water and air - is rapidly rising to become a market of over $533 billion by 2025. Some run entirely on harvested energy as with solar lake boats. Others recycle energy as with regenerative braking of cars, buses and military vehicles harvesting kinetic energy. Others use different forms of harvesting either to charge the traction batteries, or to drive autonomous device. In some cases, harvesting is making completely new forms of electric vehicle possible such as "glider" Autonomous Underwater Vehicles (AUVs) that can stay at sea for years, gaining electricity from both wave power and sunshine. Multiple forms of energy harvesting on one vehicle are becoming more common from cars to superyachts.
