Aerospace-Solenoid Valve, Hydraulic, Three Way, Two Position, Direct Acting

2019-10-10
WIP
ARP4945B
This SAE Aerospace Recommended Practice (ARP) is intended as a guide to aid in the specifying and testing of direct acting three way, two position, single and multiple coil, normally open and normally closed solenoid valves used for the pilot actuation of hydraulic control systems and the control of hydraulic components. The information presented should be useful in standardizing terminology, in specifying requirements and performance parameters, and in defining test methods. The recommendations do not restrict or attempt to define the internal design features of solenoid valves. Standard mechanical, electrical and fluid porting interfaces are recommended to provide commonalty, interchangeability, design flexibility and to be more affordable. In general, this recommended practice is directed toward solenoid valves for use in military and commercial flight control and hydraulic actuation systems.

Fundamentals in Wire Selection and Sizing for Aerospace Applications

2019-10-10
WIP
AIR6540A

The scope of this report is to capture fundamental principles of selecting a wire size for an aerospace application using the method prescribed in the AS50881 standard and additional calculations, not found in AS50881, to ensure the wire selection will adequately perform in the specific physical and environment conditions.

This report covers wire selection and sizing as part of the electrical wire interconnection systems (EWIS) used in aerospace vehicles. Aerospace vehicles include manned and unmanned airplanes, helicopters, lighter-than-air vehicles, missiles, and external pods. This document does not apply to wiring inside of airborne electronic equipment but shall apply to wiring externally attached to such equipment.

The Effects of Front-Mounted Accessories on Air Bag Sensors and Crashworthiness

2019-10-09
CURRENT
J2431_201910
Almost all light trucks now are being manufactured with at least a driver side air bag and all will have dual air bags by 1998. The driving forces behind this feature are occupant safety, federal regulations, and competition in thie industry. Along with the booming popularity of pickups and SUVs, they are commonly accessorized with a wide variety of products. Many acessories for four-wheel drives in particular are mounted on the front of the vehicle. These products include grille/brush guards, winches, snow plows, replacement bumpers, bicycle carriers, etc. Concerns have arisen over the compatibility of these accessories with the vehicle's air bag system. The vehicle manufacuters are concerned because of their huge investment in design and crash test verificaiton of the complete vehicle system and keen awareness of the federal regulations. The crushability of the front bumper and supporting structure are key elements in the system, so alterations to that area become logical concerns.

Passenger Car Side Door Latch Systems

2019-10-09
CURRENT
J839_201910
This SAE Recommended Practice establishes minimum performance requirements and test procedures for evaluating and testing passenger car side door latch systems. It is limited to tests that can be conducted on uniform test fixtures and equipment in commercially available laboratory test facilities. The test procedures and minimum performance requirements outlined in this document are based on currently available engineering data. It is intended that all portions of the document will be periodically reviewed and revised, as additional knowledge regarding vehicle latch performance under impact conditions is developed.
