Residual Stress Measurement and Classification, Metallic Structural Alloy Products and Finished Parts

2023-05-22

CURRENT

AS7045

The purpose of this standard is to provide uniform methods for defining, quantifying, and classifying the residual stress in metallic structural alloy products and finished parts. These stresses may exist within a single element, or they may be the result of a joining process. Such quantification and classification may be required when residual stresses within mill stock or preforms can impact further in-process distortion during machining or other processes, and when residual stresses within finished components can impact final mechanical properties and performance (especially strength, durability, and fracture performance).

CURRENT

J2984_202109

The chemistry identification system is intended to support the proper and efficient recycling of rechargeable battery systems used in transportation applications with a maximum voltage greater than or equal to 12 V. These applications include propulsion, starting/lighting/ignition, and providing power to other vehicle equipment. Other battery systems such as non-rechargeable batteries, batteries in electronics, and telecom/utility batteries are not considered in the development of this specification. This does not preclude these systems from adapting the format proposed if they so choose.

J1380_202011

The force, torque, and energy methods of measurement are all in common use and should yield the same test results. Effects of steering, traction, and non steady-state tire operations are excluded from the recommended practice because they are still in the research stage. Methods of correcting laboratory data to road conditions are being developed.

CURRENT

AIR5744

The intent of this report is to encourage that the thermal management system architecture be designed from a global platform perspective. Separate procurements for air vehicle, propulsion system, and avionics have contributed to the development of aircraft that are sub-optimized from a thermal management viewpoint. In order to maximize the capabilities of the aircraft for mission performance and desired growth capability, overall system efficiency and effectiveness should be considered. This document provides general information about aircraft Thermal Management System Engineering (TMSE). The document also discusses approaches to processes and methodologies for validation and verification of thermal management system engineering. Thermal integration between the air vehicle, propulsion system, and avionics can be particularly important from a thermal management standpoint.

CURRENT

ARP1816D

This SAE Aerospace Recommended Practice (ARP) describes three general types of Ground Support Equipment (GSE) battery chargers. The battery charger typically requiring up to 8 hours to recharge a 100% discharged battery, hereafter called “Conventional Charger.” A charger, hereafter called “Opportunity Charger,” which has the ability to charge at a slightly faster rate than a conventional charger. A charger, hereafter called “Fast Charger,” which has the ability to charge at a much faster rate than a conventional charger. Recommendations that apply to all types will refer generically to “charger.”
