An Introduction to Aircraft Thermal Management [PDF ebook] 

支持

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.
