Cooperative Perception System

2018-09-18
WIP
J2945/8
This document provides a description for a V2X-capable device such as a vehicle, an infrastructure or a portable device to broadcast its perception information of other road users/objects nearby, to realize cooperative perception sharing, and to improve the perception performance of other V2X-capable devices/systems. #11;The concept of such perception sharing system can be: The host system is capable of transmitting and receiving V2X messages such as BSM and PSM messages. In the meanwhile the host system is capable of detecting nearby road users/objects such as foreign objects, vehicles and pedestrians. The host system can determine whether the detected objects are V2X enabled or not, and translate the detected objects to messages such as a new cooperative perception message, and/or an extension of messages such as BSMs/PSMs, and broadcast these messages.

Aircraft Tow Bar

2018-09-18
WIP
ARP1915F
This SAE Aerospace Recommended Practice (ARP) specifies dimensional and physical requirements of tow bar connections to tractor and aircraft (see Figure 1). It is applicable to all types of commercial transport category aircraft tow bar. The purpose of this SAE Aerospace Recommended Practice (ARP) is to standardize tow bar attachments to airplane and tractor according to the mass category of the towed aircraft, so that one tow bar head with different shear levels can be used for all aircraft that are within the same mass category and are manufactured in compliance with AS1614 or ISO 8267.

Trimmable Horizontal Stabilizer Actuator Descriptions

2018-09-18
WIP
AIR6052A
The scope of the project it to develop a comprehensive description document that displays various examples of aircraft systems driving Trimmable Horizontal Stabilizers. The main focus is on mechanical systems which may be actuated hydraulically or electrically. The document is intended as an overview for those specifying or designing Horizontal Stabilizer Trim Actuators in order to compare existing solutions as reference for implementation in new aircraft programs.

Test Method for Evaluating the Electrochemical Resistance of Coolant System Hoses and Materials

2018-09-18
WIP
J1684
This test method provides a standardized procedure for evaluating the electrochemical resistance of automotive coolant hose and materials. Electrochemical degradation has been determined to be a major cause of EPDM coolant system hose failures. The test method consists of a procedure which induces voltage to a test specimen while it is exposed to a water/coolant solution. Method #1, referred to as a "Brabolyzer" test, is a whole hose test. Method #2, referred to as a "U" tube test, uses cured plate samples or plates prepared from tube material removed from hose (Method No. 2 is intended as a screening test only). Any test parameters other than those specified in this SAE Recommended Practice, are to be agreed to by the tester and the requester.

Test Method for Evaluating the Electrical Resistance of Coolant System Hose Covers

2018-09-18
WIP
J2790
This test method provides a standardized procedure for evaluating the electrical resistance of automotive coolant hose covers. It is know that an electrical potential exists between the engine and the radiator. Coolant hose cover conductivity has been determined to be a factor in reduced hose clamp life when vehicle build variations allow possible contact of the hose or the clamp to contact metal components on the radiator and engine thus completing an electrical circuit. The ensuing electrical current can undercut the clamp protective coating, leaving it vulnerable to the corrosive effects of road salts, moisture, and other environmental contaminants. SAE Recommended Practice J1684 addresses the conductivity of the tube portion of the coolant hose.
