Download or read book Aircraft Thermal Management written by Mark Ahlers and published by SAE International. This book was released on 2016-03-02 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: These three volumes entitled Advances in Hypersonics contain the Proceedings of the Second and Third Joint US/Europe Short Course in Hypersonics which took place in Colorado Springs and Aachen. The Second Course was organized at the US Air Force Academy, USA in January 1989 and the Third Course at Aachen, Germany in October 1990. The main idea of these Courses was to present to chemists, com puter scientists, engineers, experimentalists, mathematicians, and physicists state of the art lectures in scientific and technical dis ciplines including mathematical modeling, computational methods, and experimental measurements necessary to define the aerothermo dynamic environments for space vehicles such as the US Orbiter or the European Hermes flying at hypersonic speeds. The subjects can be grouped into the following areas: Phys ical environments, configuration requirements, propulsion systems (including airbreathing systems), experimental methods for external and internal flow, theoretical and numerical methods. Since hyper sonic flight requires highly integrated systems, the Short Courses not only aimed to give in-depth analysis of hypersonic research and technology but also tried to broaden the view of attendees to give them the ability to understand the complex problem of hypersonic flight. Most of the participants in the Short Courses prepared a docu ment based on their presentation for reproduction in the three vol umes. Some authors spent considerable time and energy going well beyond their oral presentation to provide a quality assessment of the state of the art in their area of expertise as of 1989 and 1991.

Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to studies of unsteady heat and mass exchange processes taking into account thermochemical destruction of thermal protective materials, research of transpiration cooling systems, thermal protection of composite materials exposed to low-energy disturbances, as well as the numerical solution of heat and mass transfer of the exchange. It proposes several mathematical models of passive and active thermal protection systems with regard to factors such as surface ablation, surface roughness, phase transition of a liquid in porous materials, rotation of the body around its longitudinal axis, and exposure to low-energy disturbances. The author studies the possibilities to control thermochemical destruction and heat mass exchange processes in transpiration cooling systems exposed to low-energy disturbances. The numerical analysis of the heat and mass exchange process in carbon plastics under repeated impulse action is also presented. The numerical solutions of problems are compared with the known experimental data. The book is intended for specialists in the field of thermal protection and heat mass exchange, as well as graduate and undergraduates in physics and mathematics.

Book excerpt: The objective of the proposed effort was to evaluate the U.S. Air Force sponsored Vehicle Integrated Thermal Management Analysis Code (VITMAC) for: (1) including an optimization/expert systems architecture for analyzing thermal/fluid network configurations at the component, subsystems, and system level, and (2) coupling VITMAC with engine performance and cycle codes to provide a more integrated mission analysis capability as well as more accurate definitions of thermal loads. This effort resulted in the inclusion in VITMAC of a flow condition optimization method which automatically determines component operation to match user-specified thermal circuit operating conditions. This was the first step in implementing a plan for a multi-level optimization method which was developed for a Phase II program. Various engine performance and cycle models where evaluated which resulted in the recommendation that VITMAC be linked with APL's RJPA ram/scramjet engine performance code as well as NASA's CEA rocket performance model and NNEP turbine engine cycle code. Finally, a plan for commercializing VITMAC was developed which includes: (1) enhancing the graphical user Interface (GUI) to make it more user friendly and robust, (2) organizing workshops to provide industrial experts with influence on and knowledge of VITMAC capabilities, (3) providing end-user support and training and, (4) developing a market plan for transferring the technology for aircraft and non-aircraft applications.

This book was released on 2017 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: System optimization and design of aircraft is required to achieve many of the long term objectives for future aircraft platforms. To address the necessity for system optimization a vehicle-level aircraft model has been developed in a multidisciplinary modeling and simulation environment. Individual subsystem models developed exclusively in MATLAB-SimulinkTM, representing the vehicle dynamics, the propulsion, electrical power, and thermal systems, and their associated controllers, are combined to investigate the energy and thermal management issues of tactical air vehicle platforms. A thermal vehicle level tip-to-tail model allows conceptual design trade studies of various subsystems and can quantify performance gains across the aircraft. Often one of the main objectives is system efficiency for reduction in fuel use for a given mission. System efficiency can be quantified by either a 1st or 2nd law thermodynamic analysis. A 2nd law exergy analysis can provide a more robust means of accounting for all of the energy flows within and in between subsystems. These energy flows may be thermal, chemical, electrical, pneumatic, etc. Energy efficiency gains in the transient domain of the aircraft's operation provide untapped opportunities for innovation. To utilize a 2nd law analysis to quantify system efficiencies, an exergy analysis approach is taken. This work demonstrates the implementation of a transient exergy analysis for a thermal management subsystem component found on traditional aircraft platforms. The focus of this work is on the development of a dynamic air cycle machine (ACM) model and implementation of an exergy based optimization analysis. This model is utilized in tandem with a bench top ACM experimental unit at the Air Force Research Laboratory's Modeling, Simulation, Analysis and Testing (MSAT) lab. Individual elements, including compressor, turbines, heat exchangers and control valves have been combined to investigate the behavior of a typical ACM. The experimental test stand is designed and constructed to be used as a method to validate models developed. Combining the results gained from the simulation studies, specifically the exergy analysis, and the experimental setup, a methodology is formulated for system level optimization. By leveraging this approach, future simulation studies can be implemented on various system architectures to generate accurate models and predictive analysis.
