Classical Feedback Control with Nonlinear Multi-Loop Systems describes the design of high-performance feedback control systems, emphasizing the frequency-domain approach widely used in practical engineering. It presents design methods for high-order nonlinear single- and multi-loop controllers with efficient analog and digital implementations. Bode integrals are employed to estimate the available system performance and to determine the ideal frequency responses that maximize the disturbance rejection and feedback bandwidth. Nonlinear dynamic compensators provide global stability and improve transient responses. This book serves as a unique text for an advanced course in control system engineering, and as a valuable reference for practicing engineers competing in today's industrial environment.

In 1962 Dean Acheson famously described Britain as having lost an Empire but not yet found a role. Perhaps nowhere is this more apparent than in the realms of nuclear weapons. An increasingly marginal world power, successive post-war British governments felt that an independent nuclear deterrent was essential if the country was to remain at the top table of world diplomacy. Focusing on a key twenty-year period, this study explores Britain's role in efforts to bring about a nuclear test ban treaty between 1954 and 1973. Taking a broadly chronological approach, it examines the nature of defence planning, the scientific goals that nuclear tests were designed to secure, Anglo-American relationships, the efficacy of British diplomacy and its contribution to arms control and disarmament. A key theme of the study is to show how the UK managed to balance the conflicting pressures created by its determination to remain a credible nuclear power whilst wanting to pursue disarmament objectives, and how these pressures shifted over the period in question. Based on a wealth of primary sources this book opens up the largely ignored subject of the impact of arms control on the UK nuclear weapons programme. Its appraisal of the relationship between the requirements and developments of the UK nuclear weapons programme against international and domestic pressures for a test ban treaty will be of interest to anyone studying post-war British defence and foreign policy, history of science, arms control, disarmament and non-proliferation and international relations. It also provides important background information on current events involving nuclear proliferation and disarmament.

Want to know not just what makes rockets go up but how to do it optimally? Optimal control theory has become such an important field in aerospace engineering that no graduate student or practicing engineer can afford to be without a working knowledge of it. This is the first book that begins from scratch to teach the reader the basic principles of the calculus of variations, develop the necessary conditions step-by-step, and introduce the elementary computational techniques of optimal control. This book, with problems and an online solution manual, provides the graduate-level reader with enough introductory knowledge so that he or she can not only read the literature and study the next level textbook but can also apply the theory to find optimal solutions in practice. No more is needed than the usual background of an undergraduate engineering, science, or mathematics program: namely calculus, differential equations, and numerical integration. Although finding optimal solutions for these problems is a complex process involving the calculus of variations, the authors carefully lay out step-by-step the most important theorems and concepts. Numerous examples are worked to demonstrate how to apply the theories to everything from classical problems (e.g., crossing a river in minimum time) to engineering problems (e.g., minimum-fuel launch of a satellite). Throughout the book use is made of the time-optimal launch of a satellite into orbit as an important case study with detailed analysis of two examples: launch from the Moon and launch from Earth. For launching into the field of optimal solutions, look no further!

First published in 1997, this volume responds to the increase in air traffic, as there has been a great deal of work by the nations of the world, under the auspices of ICAO, toward developing the concept for a future air navigation infrastructure to serve worldwide civil aviation efficiency. Even though the concept is well described and implementation is beginning, only technical manuals are available to advance the systems concept. This book describes the global vision for the Future Air Navigation System (FANS) and is the first text of its kind dedicated solely to Communications Navigation, Surveillance/Air Traffic Management and the CNS/ATM systems concept. In addition to the technical issues associated with CNS/ATM, the book also examines institutional, economic, labour and Human Factors issues. It is designed as a text usable in the classroom environment in universities and aviation technical schools.

The combined observational power of the multiple earth observing satellites is currently not being harnessed holistically to produce more durable societal benefits. We are not able to take complete advantage of the prolific amount of scientific output and remote sensing data that are emerging rapidly from satellite missions and convert them quickly into decision-making products for users. The current application framework we have appears to be an analog one lacking the absorption bandwidth required to handle scientific research and the voluminous (petabyte-scale) satellite data. This book will tackle this question: "How do we change this course and take full advantage of satellite observational capability for a more sustainable, happier and safer future in the coming decades?"

The Early Development of the Aviation Industry: Entrepreneurs of the Sky provides an introduction to the world of the early aviation industry and the business endeavours of the original aviators. Many of the first pioneers who flew heavier-than-air planes went on to develop considerable industrial concerns. In doing so they exhibited a number of entrepreneurial qualities, which provide useful case studies for those interested in studying how successful entrepreneurs create or develop opportunities at the inception and emergence of high-tech industries. This book looks at the careers of pioneer aviators in the United States, Britain and France such as A.V. Roe, Thomas Sopwith, Glenn Curtiss and William Boeing. It examines this group of entrepreneurs during the start-up and early development stages of an emerging industry undergoing considerable technological change, and relates this experience to contemporary studies and experiences of entrepreneurship. The book explores what made these men successful in their entrepreneurial endeavours to help promote a better understanding of what makes an entrepreneur and what business and economic conditions are needed to allow such men to be successful. This book makes a major contribution to our knowledge of the development of the twentieth century economy and is essential reading for students and academics who are interested in the development of aviation and the nature of entrepreneurial behaviour.

By the middle of 1918 the British Army had successfully mastered the concept of 'all arms' warfare on the Western Front. This doctrine, integrating infantry, artillery, armoured vehicles and - crucially - air power, was to prove highly effective and formed the basis of major military operations for the next hundred years. Yet, whilst much has been written on the utilisation of ground forces, the air element still tends to be studied in isolation from the army as a whole. In order to move beyond the usual 'aircraft and aces' approach, this book explores the conceptual origins of the control of the air and the role of the Royal Flying Corps (RFC) within the British army. In so doing it addresses four key themes. First, it explores and defines the most fundamental air power concept - the control of the air - by examining its conceptual origins before and during the First World War. Second, it moves beyond the popular history of air power during the First World War to reveal the complexity of the topic. Third, it reintegrates the study of air power during the First World War, specifically that of the RFC, into the strategic, operational, organisational, and intellectual contexts of the era, as well as embedding the study within the respective scholarly literatures of these contexts. Fourth, the book reinvigorates an entrenched historiography by challenging the usually critical interpretation of the RFC's approach to the control of the air, providing new perspectives on air power during the First World War. This includes an exploration of the creation of the RAF and its impact on the development of air power concepts.

This book compiles a variety of experimental data on blast waves. The book begins with an introductory chapter and proceeds to the topic of blast wave phenomenology, with a discussion on Rankine-Hugoniot equations and the Friedlander equation, used to describe the pressure-time history of a blast wave. Additional topics include arrival time measurement, the initiation of detonation by exploding wires, a discussion of TNT equivalency, and small scale experiments. Gaseous and high explosive detonations are covered as well. The topics and experiments covered were chosen based on the comparison of used scale sizes, from small to large. Each characteristic parameter of blast waves is analyzed and expressed versus scaled distance in terms of energy and mass. Finally, the appendix compiles a number of polynomial laws that will prove indispensable for engineers and researchers.

This book analyzes various properties and structures of ice from the point of view to solve problems in civil aviation. The Arctic zone of the Russian Federation, together with large territories of Siberia and the Far East, is a zone, that is insufficiently provided with ground navigation facilities, as well as platforms and airfields for landing aircraft, including in the event of unpredictable situations. However, most of this area, especially in winter, is covered with ice, which can be used to solve this problem. The possibility of using ice sheets for the construction of airfields or the location of ground-based flight support facilities requires careful study and analysis. This book is devoted to the study of the properties and structure of ice, with a view for use in civil aviation to construct ice airfields and the placement of ground-based flight support facilities.

The aviation industry is unique in two major ways: firstly, it has a long history of government involvement dating back to the early days of aviation; and secondly, its primary concern is the safety of its passengers and crew. These features highlight the importance of ethical decision-making at all levels of the industry. However, well-publicized problems such as the disappearance of Malaysia Airlines Flight 370 highlight the need for ethics to take a more prominent role in the field. Ethical Issues in Aviation focuses on both past and current topics in aviation, providing the reader with an overview of the major themes in aviation ethics that cover a broad range of subjects. Contributors include academics who do research in the field as well as professionals who provide first-hand accounts of the ethical situations that arise in the aviation industry. This second edition has been thoroughly revised throughout to bring it up to date, and features several new chapters that cover recent events and topics. This book enhances student learning by providing faculty, students, and those interested in aviation with discussion of the most pressing ethical issues that continue to impact the industry.

Flight training and flying are hazardous activities that demand the most of human operators, whether they be pilots or other factors (maintainers, air traffic controllers, managers, regulators) involved in the complex aviation system. 'Aerospace Clinical Psychology' serves as a handbook for dealing with aviators and other operators, those seen as patients as well as those functioning 'normally', who none-the-less wish to improve their performance. This book has much to offer the audiences who intersect the Human Factors and clinical areas of aviation and operators in extreme environments. It deftly defines specific touchstone areas such as selection, training, accident investigation, measurement and testing, and practical interventions. The little-margin-for-error realm of aviation exposes operators to stress and risk on a daily basis. 'Aerospace Clinical Psychology' provides a blueprint for combining the talents of clinical psychologists with flight surgeons and Human Factors practitioners to enhance safety and efficiency.
