Book Description
Provides a significant update to the definitive book on aircraft system design This book is written for anyone who wants to understand how industry develops the customer requirement for aircraft into a fully integrated, tested, and qualified product that is safe to fly and fit for purpose. The new edition of Design and Development of Aircraft Systems fully expands its already comprehensive coverage to include both conventional and unmanned systems. It also updates all chapters to bring them in line with current design practice and technologies taught in courses at Cranfield, Bristol, and Loughborough universities in the UK. Design and Development of Aircraft Systems, 3rd Edition begins with an introduction to the subject. It then introduces readers to the aircraft systems (airframe, vehicle, avionic, mission, and ground systems). Following that comes a chapter on the design and development process. Other chapters look at design drivers, systems architectures, systems integration, verification of system requirements, practical considerations, and configuration control. The book finishes with sections that discuss the potential impact of complexity on flight safety, key characteristics of aircraft systems, and more. Provides a holistic view of aircraft system design, describing the interactions among subsystems such as fuel, navigation, flight control, and more Substantially updated coverage of systems engineering, design drivers, systems architectures, systems integration, modelling of systems, practical considerations, and systems examples Incorporates essential new material on the regulatory environment for both manned and unmanned systems Discussion of trends towards complex systems, automation, integration and the potential for an impact on flight safety Design and Development of Aircraft Systems, 3rd Edition is an excellent book for aerospace engineers, researchers, and graduate students involved in the field.

Book Description
The primary human activities that release carbon dioxide (CO2) into the atmosphere are the combustion of fossil fuels (coal, natural gas, and oil) to generate electricity, the provision of energy for transportation, and as a consequence of some industrial processes. Although aviation CO2 emissions only make up approximately 2.0 to 2.5 percent of total global annual CO2 emissions, research to reduce CO2 emissions is urgent because (1) such reductions may be legislated even as commercial air travel grows, (2) because it takes new technology a long time to propagate into and through the aviation fleet, and (3) because of the ongoing impact of global CO2 emissions. Commercial Aircraft Propulsion and Energy Systems Research develops a national research agenda for reducing CO2 emissions from commercial aviation. This report focuses on propulsion and energy technologies for reducing carbon emissions from large, commercial aircraftâ€" single-aisle and twin-aisle aircraft that carry 100 or more passengersâ€"because such aircraft account for more than 90 percent of global emissions from commercial aircraft. Moreover, while smaller aircraft also emit CO2, they make only a minor contribution to global emissions, and many technologies that reduce CO2 emissions for large aircraft also apply to smaller aircraft. As commercial aviation continues to grow in terms of revenue-passenger miles and cargo ton miles, CO2 emissions are expected to increase. To reduce the contribution of aviation to climate change, it is essential to improve the effectiveness of ongoing efforts to reduce emissions and initiate research into new approaches.

Book Description
This thesis proposes a multi-disciplinary optimization framework for the design of aircraft electro-thermal energy systems. In this framework, components are modeled using a method called graph-based modeling. Graph-based modeling utilizes the principle of transient conservation of energy to model the states of a control volume. With this modeling structure, an energy system's state equations can be expressed in terms of transient conservation of energy and these equations can be combined into a set of compact matrix equations. This compact representation of energy systems allows multiple energy domains to be coupled and simulated together with one set of modeling equations. Graph-based modeling also allows easy access to the network structure of the system. This modeling approach is employed within an optimal control formulation to optimize both system-level design parameters and open-loop control trajectories. In total, this framework will allow for multi-disciplinary modeling and design of aircraft energy systems. Case studies for a series hybrid-electric aircraft architecture demonstrate how key parameters of the electrical system, such as battery capacity, can be designed together with the associated thermal management systems for a representative transient flight.

Book Description
The environmental impact of hydrocarbon-burning aircraft is one of the main motivations for the move to electric propulsion in aerospace. Also, cars, buses, and trucks are incorporating electric or hybrid-electric propulsion systems, reducing the pressure on hydrocarbons and lowering the costs of electrical components. The economies of scale necessitated by the automotive industry will help contain costs in the aviation sector as well. The use of electric propulsion in airplanes is not a new phenomenon. However, it is only recently that it has taken off in a concrete manner with a viable commercial future. The Electric Flight Technology: Unfolding of a New Future reviews the history of this field, discusses the key underlying technologies, and describes how the future for these technologies will likely unfold, distinguishing between all-electric (AE) and hybrid-electric (HE) architectures. Written by Dr. Ravi Rajamani, it covers the essential information needed to understand this new technology wave taking hold in the aerospace industry. The Electric Flight Technology: Unfolding of a New Future covers fundamental topics such as: • The history of electric propulsion, including its evolution from using traditional electricity, to solar power to batteries as sources to sustain propulsion and flight. • The various architectures being considered for electric aircraft, specifically small general aviation (GA) aircraft and larger business jets; single-aisle commercial aircraft; and larger twin-aisle commercial aircraft. • The various systems and subsystems of an electric aircraft, along with how various subsystems in the vehicle can be integrated in a more optimal manner. In the future, the existing tube-and-wing configuration will not be the only available architecture; instead we will be more likely to find an architecture where the propulsion system is embedded within the airframe. • The future trends in this arena and what we can expect to see in the next decade or so.

Book Description
Aircraft Propulsion and Gas Turbine Engines, Second Edition builds upon the success of the book’s first edition, with the addition of three major topic areas: Piston Engines with integrated propeller coverage; Pump Technologies; and Rocket Propulsion. The rocket propulsion section extends the text’s coverage so that both Aerospace and Aeronautical topics can be studied and compared. Numerous updates have been made to reflect the latest advances in turbine engines, fuels, and combustion. The text is now divided into three parts, the first two devoted to air breathing engines, and the third covering non-air breathing or rocket engines.

Book Description
Fundamentals of Electric Aircraft, Second Edition was developed to explain what the electric aircraft stands for by offering an objective view of what can be expected from the giant strides in innovative architectures and technologies enabling aircraft electrification. This edition features new illustrations and photographs throughout. Through tangible case studies, a deep insight is provided into this paradigm shift cutting across various aircraft segments – from General Aviation to Large Aircraft. Addressing design constraints and timelines foreseen to reach acceptable performance and maturity levels, Fundamentals of Electric Aircraft, Second Edition puts forward a general view of the progress made to date and what to expect in the years to come. Drawing from the expertise of four industry veterans, Pascal Thalin (editor/contributor), Ravi Rajamani, Jean-Charles Maré, and Sven Taubert (contributors), it addresses futuristic approaches but does not depart too far from the operational down-to-earth realities of everyday business. Fundamentals of Electric Aircraft, Second Edition also offers analyses on how performance enhancements and fuel burn savings may bring more value for money as long as new electric technologies deliver on their promises.
