  • Introduction

    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. Multiple terms are used in the literature to describe this type of analysis, The purpose of this analytical modeling 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, IESA is also considered to be a key enabler for the successful implementation of the next-generation jet fighter weapons systems and countermeasures. In 2014, the Aerospace Systems Directorate of the U.S. Air Force Research Laboratory launched the Center for Integrated Thermal Management of Aerospace Vehicles due to concerns over thermal issues being a limiting factor in the performance of future military aircraft.

    This book contains a selection of papers relevant to aircraft thermal management IESA published by SAE. The papers 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. While the modeling discussed primarily refers to military aircraft, the same tools and methods may be adapted for commercial aircraft simulations following minor modifications.

    Additional information on the closely related topic of Aircraft Thermal Management is available from SAE AIR 5744 issued by the AC-9 Aircraft Environmental System Committee and the book, Aircraft Thermal Management: Systems Architectures.

    SAE AIR 5744 defines the discipline of aircraft thermal management system engineering, while Aircraft Thermal Management: Systems Architectures discusses the more Efficient means of managing aircraft heat generation being developed using the types of analysis methods and programs discussed in this book.
