Aircraft Thermal Management (ATM)focuses on how to manage heat in an aircraft to meet the temperature requirements for passengers and vehicle. This primarily involves removing heat and protecting equipment, systems, and structure from heat sources that could raise their temperature beyond design limits. Crew and passengers must be neither too hot nor too cold during airplane operations. Thus, maintaining thermal comport is critically important, and not a trivial operation. Written by Mark F. Ahlers, a retired Boeing Technical Fellow and its first Thermal Marshal, An Introduction to Aircraft Thermal Management is the ultimate source of knowledge concerning: Temperature and thermal related requirements Airplane-generated heat sources External heat sources Aircraft heat sinks Fire and Failures Environmental control systems Thermal design Analytical modeling Analytical software Testing Military aircraft thermal management Fully illustrated and amply referenced, An Introduction to Aircraft Thermal Management provides a very balanced approach between theory and practice, best practices and technical insights. It is a must-have reference for both young engineers starting in the filed and for seasoned professionals willing to re-sharpen their skills.

Aircraft thermal management (ATM) is increasingly important to the design and operation of commercial and military aircraft due to rising heat loads from expanded electronic functionality, electric systems architectures, and the greater temperature sensitivity of composite materials compared to metallic structures. It also impacts engine fuel consumption associated with removing waste heat from an aircraft. More recently the advent of more electric architectures on aircraft, such as the Boeing 787, has led to increased interest in the development of more efficient ATM architectures by the commercial airplane manufacturers. The ten papers contained in this book describe aircraft thermal management system architectures designed to minimize airplane performance impacts which could be applied to commercial or military aircraft. Additional information on Aircraft Thermal Management System Architectures is available from SAE AIR 5744 issued by the AC-9 Aircraft Environmental System Committee and the SAE book Aircraft Thermal Management Integrated Analysis (PT-178). SAE AIR 5744 defines the discipline of aircraft thermal management system engineering while Aircraft Thermal Management Integrated Analysis discusses approaches to computer simulation of the simultaneous operation of all systems affecting thermal management on an aircraft.

The simultaneous operation of all systems generating, moving, or removing heat on an aircraft is simulated using integrated analysis which is called Integrated Energy System Analysis (IESA) for this book. Its purpose is to understand, optimize, and validate more efficient system architectures for removing or harvesting the increasing amounts of waste heat generated in commercial and military aircraft. In the commercial aircraft industry IESA is driven by the desire to minimize airplane operating costs associated with increased system weight, power consumption, drag, and lost revenue as cargo space is devoted to expanded cooling systems. In military aircraft thermal IESA is also considered to be a key enabler for the successful implementation of the next generation jet fighter weapons systems and countermeasures. This book contains a selection of papers relevant to aircraft thermal management IESA published by SAE International. They cover both recently developed government and industry- funded thermal management IESA such as the Integrated Vehicle Energy Technology (INVENT) program, and older published papers still relevant today which address modeling approaches.

"Aircraft thermal management (ATM) is increasingly important to the safe and efficient design and operation of commercial and military aircraft due to the steadily rising heat loads. These now come from expanded electronic functionality, more electric systems, and the greater temperature sensitivity of composite materials relative to traditional metallic designs (for commercial aircraft). Military aircraft designers also face the added challenges of removing the waste heat from advanced weapon systems and countermeasures. More recently, commercial-off-the-shelf (COTS) electronic components, which typically have more stringent cooling requirements than their military grade counterparts, are also contributors. ... The papers contained in this book describe aircraft thermal management system architectures designed to minimize airplane performance impacts, which could be applied to commercial or military aircraft."--Back cover.

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.
