Optimal aircraft design is impossible without a parametric representation of the geometry of the airframe. We need a mathematical model equipped with a set of controls, or design variables, which generates different candidate airframe shapes in response to changes in the values of these variables. This model''s objectives are to be flexible and concise, and capable of yielding a wide range of shapes with a minimum number of design variables. Moreover, the process of converting these variables into aircraft geometries must be robust. Alas, flexibility, conciseness and robustness can seldom be achieved simultaneously.Aircraft Aerodynamic Design: Geometry and Optimization addresses this problem by navigating the subtle trade-offs between the competing objectives of geometry parameterization. It beginswith the fundamentals of geometry-centred aircraft design, followed by a review of the building blocks of computational geometries, the curve and surface formulations at the heart of aircraft geometry. The authors then cover a range of legacy formulations in the build-up towards a discussion of the most flexible shape models used in aerodynamic design (with a focus on lift generating surfaces). The book takes a practical approach and includes MATLAB, Python and Rhinoceros code, as well as real-life example case studies.Key features: - Covers effective geometry parameterization within the context of design optimization- Demonstrates how geometry parameterization is an important element of modern aircraft design- Includes code and case studies which enable the reader to apply each theoretical concept either as an aid to understanding or as a building block of their own geometry model- Accompanied by a website hosting codesAircraft Aerodynamic Design: Geometry and Optimization is a practical guide for researchers and practitioners in the aerospace industry, and a reference for graduate and undergraduate students in aircraft design and multidisciplinary design optimization.

- Offers the reader a better understanding of the current challenges facing the development of the future generation of unmanned aerial vehicles- Provides insights into problems that arise and have to be solved when achieving safe and efficient autonomous aerial load transportation- Presents detailed methods for experimental implementation of the proposed algorithmsUnmanned aerial vehicles are increasingly being used to perform complex functions or to assist humans to carry out dangerous missions within dynamic environments. Other possible applications include search and rescue, disaster relief operations, environmental monitoring, wireless surveillance networks, and cooperative manipulation. Creating these types of autonomous aerial vehicles places severe demands on the design of control schemes that can adapt to different scenarios and possible changes of vehicle dynamics. In this book we address the challenging problem of employing aerial robots to transport and manipulate loads safely and efficiently. Aerial load manipulation and transportation is extremely important in emergency rescue missions as well as for military and industrial purposes. This book gives an insight into problems that can arise in aerial load transportation and suggests control systems techniques to solve them. A key focus is given on modeling of the aerial load transportation system as well as stability and robustness analysis. A detailed design and derivation of control algorithms based on adaptive control, optimal control and reinforcement learning are discussed in detail. Furthermore, an experimental testbed and controller implementation are delineated.

This book provides its reader with a good understanding of the stabilization of switched nonlinear systems (SNS), systems that are of practical use in diverse situations: design of fault-tolerant systems in space- and aircraft; traffic control; and heat propagation control of semiconductor power chips. The practical background is emphasized throughout the book; interesting practical examples frequently illustrate the theoretical results with aircraft and spacecraft given particular prominence. Stabilization of Switched Nonlinear Systems with Unstable Modes treats several different subclasses of SNS according to the characteristics of the individual system (time-varying and distributed parameters, for example), the state composition of individual modes and the degree and distribution of instability in its various modes. Achievement and maintenance of stability across the system as a whole is bolstered by trading off between individual modes which may be either stable or unstable or by exploiting areas of partial stability within all the unstable modes. The book can be used as a reference for academic research on switched systems or used by graduate students of control theory and engineering. Readers should have studied linear and nonlinear system theory and have some knowledge of switched and hybrid systems to get the most from this monograph.

La obra comienza en su primer capítulo abordando la definición y adecuación de los modelos de cálculo; con el apoyo de fotografías de estructuras reales, se analiza su modelización geométrica, de vinculacion y de acciones y, sobre todo, el modo en el que refleja su comportamiento real.El segundo capitulo se centra en el estudio de los sistemas estructurales mas sencillos: las estructuras isostaticas. En ellas se aprovecha su estricto balance entre los grados de libertad de los solidos y las ligaduras que coartan sus movimientos para determinar completamente su respuesta estructural mediante las ecuaciones de equilibrio.Una vez obtenidas las reacciones en los vinculos y las interacciones entre los solidos se entra en el analisis de sus solicitaciones internas en cada seccion transversal: los esfuerzos axiles, cortantes, momentos flectores y torsores.Finalmente un ultimo apartado acomete el calculo de las deformaciones elasticas de las cerchas y los porticos mediante procedimientos energeticos basados en el principio de los trabajos virtuales.El tercer capitulo aborda con mayor extension el analisis de las estructuras articuladas y reticuladas hiperestaticas. En este caso, considerando el exceso de vinculacion que las caracteriza, se complementan las ecuaciones de equilibrio con condiciones mas complejas de compatibilidad de deformaciones. La contribucion de cada uno de los modos de respuesta provocados por el hiperestatismo se establece en funcion de la rigidez de los distintos elementos del sistema.El libro contempla los metodos elasticos de flexibilidad y rigidez. El primero resulta mas adecuado para sistemas con grados bajos de hiperestatismo y el segundo es particularmente util en sistemas fuertemente hiperestaticos. Dentro de este ultimo se detalla el metodo slope-deflection, que no se encuentra descrito con profundidad en la bibliografia española.En el cuarto capitulo se suponen ya conocidos los esfuerzos internos de los elementos estructurales y se proporcionan unas pautas simples para su dimensionado basico. Se analizan las tensiones normales y tangenciales producidas por los diferentes tipos de esfuerzos y se procede a su combinacion y comparacion con las tensiones admisibles en el material. El texto aborda finalmente los procesos iterativos de optimizacion y presenta criterios de diseño.El ultimo capitulo incorpora una breve introduccion a la elasticidad de materiales, sus conceptos fundamentales y su formulacion matematica, como punto de partida para el estudio de los medios continuos y de sistemas estructurales con elementos bidimensionales y tridimensionales.

Making a detailed contribution to geographies of air transport and aeromobility, this book examines the practices and processes that produce particular patterns of air transport provision both regionally and globally. In so doing, it updates the seminal contributions of Eva Taylor (1945), Kenneth Sealy (1957), Brian Graham (1995) and others to the study of air transport geography. Leading scholars in the field offer a unique insight into the key developments that have occurred in the field and the implications that these developments have had for geography, geographers, and global patterns of past, present and future air transport.Although globalization and liberalization processes have greatly expanded the demand for air transport over the last two decades, the industry has experienced several major setbacks due to economic, security, and environmental concerns. Many of these impacts have been much more pronounced in some regions, such as North America and Europe while others, such as Asia-Pacific have not been as adversely affected. Accordingly, there is a clear need to examine these recent economic and geopolitical changes from a geographical perspective given the differentiated pattern of effects from global processes. Addressing this need, this volume opens with thematic chapters covering key topics such as the historical geographies, socio-cultural mobilities, environmental externalities, urban geographies, and sustainability of the global air transport industry, followed by regional analysis of the industry in Asia-Pacific, Latin America, Greater Middle East and Africa as well as North America and Europe.
