Whilst most contemporary books in the aerospace propulsion field are dedicated primarily to gas turbine engines, there is often little or no coverage of other propulsion systems and devices such as propeller and helicopter rotors or detailed attention to rocket engines. By taking a wider viewpoint, "Powered Flight - The Engineering of Aerospace Propulsion" aims to provide a broader context, allowing observations and comparisons to be made across systems that are overlooked by focusing on a single aspect alone. The physics and history of aerospace propulsion are built on step-by-step, coupled with the development of an appreciation for the mathematics involved in the science and engineering of propulsion. Combining the author''s experience as a researcher, an industry professional and a lecturer in graduate and undergraduate aerospace engineering, "Powered Flight - The Engineering of Aerospace Propulsion" covers its subject matter both theoretically and with an awareness of the practicalities of the industry. To ensure that the content is clear, representative but also interesting the text is complimented by a range of relevant graphs and photographs including representative engineering, in addition to several propeller performance charts. These items provide excellent reference and support materials for graduate and undergraduate projects and exercises. Students in the field of aerospace engineering will find that "Powered Flight - The Engineering of Aerospace Propulsion" supports their studies from the introductory stage and throughout more intensive follow-on studies.

Composite structures are most efficient in performance and production cost when combined with smart materials making them adaptable to changing operational conditions. The specific production processes of composites offer the possibility to integrate more functions thus making the structure more valuable. Active functions can be realized by smart materials, e.g. morphing, active vibration control, active structure acoustic control or structure health monitoring. The foundation is a sound understanding of materials, design methods, design principles, production technologies and adaptronics. Along the complete process chain this disciplines together deliver advanced lightweight solutions for applications ranging from mechanical engineering to vehicles, airframe and finally space structures. This book provides the scientific foundations as well as inspiring new ideas for engineers working in the field of composite lightweight structures.

Manufacturing is the basic industrial activity generating real value. Cutting and abrasive technologies are the backbone of precision production in machine, automotive and aircraft building as well as of production of consumer goods. We present the knowledge of modern manufacturing in these technologies on the basis of scientific research. The theory of cutting and abrasive processes and the knowledge about their application in industrial practice are a prerequisite for the studies of manufacturing science and an important part of the curriculum of the master study in German mechanical engineering. The basis of this book is the lecture Basics of cutting and abrasive processes (4 semester hours/3 credit hours) at the Leibniz University Hannover, which was offered to the diploma and master students specializing in manufacturing science.

The demands of the modern economic climate have led to a dramatic increase in the industrial application of model-based predictive control. Apart from PID, predictive control is probably the most popular control approach in use today. Predictive functional control (PFC) was first used to develop a model-based predictive controller that was easy to understand, implement and tune from an instrumentation engineer's perspective. In the forty years since, there have been thousands of successful applications of PFC controllers in a large and diverse group of industries. Predictive Functional Control provides readers with: a fundamental understanding of the principles associated with PFC; the basic PFC control equations to be implemented in all programmable logic controllers or digital control systems in block programming form; and tuning rules and implementation procedures. Some new features arising from the needs of the process industries are reported along with many examples of industrial applications.

Salir del ensimismamiento, experimentar las potencialidades de la formación y la cultura, abrir caminos por el mundo, tales podrían ser los enunciados de una de las más fructíferas líneas del movimiento regenerador surgido de la gran crisis española de final del siglo XIX. Algunos de sus resultados son ya bien conocidos, entre los cuales destaca con luz propia el de las pensiones en el extranjero, muy en particular de las gestionadas por la JAE desde 1907. El presente libro aborda esa misma tematica en el campo de la formacion y el desarrollo de la ciencia aplicada. Desde esa misma fecha, en efecto, iniciativas semejantes cristalizaron en pensiones de ampliacion de estudios para ingenieros y de formacion en nuevas tecnicas y procedimientos empiricos para obreros manuales procedentes de fabricas, talleres y granjas nacionales. Su organizacion fue confiada poco despues a un organismo estatal autonomo, la Junta de Patronato de Pensiones de Ingenieros y Obreros en el Extranjero (JPIOE), que desarrollara su obra ininterrumpidamente, bajo diferentes nombres, hasta mas aca de la guerra civil. Pero sobre este esqueleto basico, el trabajo se adentra ademas en un amplio espectro de cuestiones que le son inseparables. Como telon de fondo esta todo el desarrollo de la enseñanza profesional, la eclosion de las politicas sociales desarrolladas desde 1920 por el nuevo Ministerio de Trabajo, la aparicion de un nuevo tipo de reflexiones sobre la gestion del Estado y sobre la manera de abordar los problemas de la productividad del trabajo y su organizacion ante las nuevas exigencias de competitividad de la segunda revolucion industrial, las vicisitudes de la innovacion tecnica y de su transferencia y adaptacion a nuevos contextos y, en fin, los interrogantes mas generales acerca de las relaciones entre educacion y desarrollo economico.

"Stepped-up competition in the airline industry over the past 40 years profoundly changed how carriers set fares. Chapters in this volume contribute to our understanding of fare determination in this industry by examining carrier pricing behavior, such as non-linear pricing, pricing decisions associated with strategic alliances, competition from low cost carriers, and the challenges faced by carriers experiencing financial distress. These contributions present nuanced analyses of fare determination that include new ways of examining whether the prices charged by carriers are consumer welfare-enhancing. Examination of airline carrier pricing only tells part of the story of firm behavior, as analysis of carriers¿ ability to provide quality services is also significant in understanding the economics of this industry. This volume includes chapters examining non-price characteristics of business operations, such as frequency of service, passenger safety, availability of aircraft types for different transportation services, and the geographic distribution of air transportation-related noise by aircraft departures and arrivals at airports. "
