Counterfeit Electronic Parts and Their Impact on Supply Chains

2014-10-20
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.

Energy Harvesting/Regeneration for Electric Vehicles Land, Water & Air 2015-2025

2014-12-01
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.

Fluid Couplings for Spacecraft Servicing, Preparation of Specification for, Metric

1993-06-09
CURRENT
MAP2261
This SAE Metric Aerospace Recommended Practice (MAP) establishes the requirements for preparing a specification for fluid couplings for spacecraft servicing. The objective of this document is to provide design, development, verification, storage, and delivery requirement guidelines for the preparation of specifications for fluid couplings and the ancillary hardware for use with serviceable spacecraft designed for use in the space environment. The couplings shall be capable of resupplying storable propellants, cryogenic liquids, and gases to a variety of spacecrafts.
