SAE 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. Due to these factors, this report is written to encourage the development of a more comprehensive system engineering approach to help eliminate and/or reduce mission limitations as a result of materials and components nearing temperature limits. This SAE Aerospace Information Report is intended to provide reference and background information pertaining to Aircraft Thermal Management System Engineering. This AIR will provide a standard definition for the subject area and provide critical insight to the requirements engineering activities required for execution. This document provides guidance encouraging platform design and procurement be pursued from a system level perspective to optimize the capabilities of aircraft for mission performance and vehicle operational goals with thermal management as an objective.AIR5744 has been reaffirmed to comply with the SAE Five-Year Review policy.
