The field of Large Eddy Simulation (LES) and hybrids is a vibrant research area. This book runs through all the potential unsteady modelling fidelity ranges, from low-order to LES. The latter is probably the highest fidelity for practical aerospace systems modelling. Cutting edge new frontiers are defined.
One example of a pressing environmental concern is noise. For the accurate prediction of this, unsteady modelling is needed. Hence computational aeroacoustics is explored. It is also emerging that there is a critical need for coupled simulations. Hence, this area is also considered and the tensions of utilizing such simulations with the already expensive LES.

This work has relevance to the general field of CFD and LES and to a wide variety of non-aerospace aerodynamic systems (e.g. cars, submarines, ships, electronics, buildings). Topics treated include unsteady flow techniques; LES and hybrids; general numerical methods; computational aeroacoustics; computational aeroelasticity; coupled simulations and turbulence and its modelling (LES, RANS, transition, VLES, URANS). The volume concludes by pointing forward to future horizons and in particular the industrial use of LES. The writing style is accessible and useful to both academics and industrial practitioners.

TheseriesAdvancesinIndustrialControl aimsto reportandencouragete- nologytransferincontrolengineering.Therapiddevelopmentofcontrolte- nology has an impact on all areas of the control discipline. New theory, new controllers, actuators, sensors, new industrial processes, computer methods, new applications, new philosophies, new challenges. Much of this devel- ment work resides in industrial reports, feasibility study papers and the - ports of advanced collaborative projects. The series o?ers an opportunity for researchersto present an extended exposition of such new work in all aspects of industrial control for wider and rapid dissemination. Autonomy for aerial, land, and marine (surface and underwater) vehicles is an ever-expanding ?eld of industrial control engineering in which there is signi?cant international interest. Currently, there are many prototypes and working autonomous vehicles in all the ?elds of application; however, some areas are better developed than others. Meanwhile in the control conference literature it is possible to see that frontier research has reached the pr- lems of working with groups, convoys or swarms of cooperating autonomous vehicles. The tasks that autonomous mobiles can tackle are very often either h- ardous, or, conversely, routine, wheretheuseofaninsitu humanoperatoristo be avoided, or simply technically (and economically) unnecessary. Typically, such tasks involve inspection, monitoring, and detection. For example, - manned aerial vehicles (UAVs) can be used to perform airborne sea searches, inspect long-distance power lines or oil and gas pipelines (particularly those traversing hostile, or hazardous terrain), monitor environmental or meteo- logical variables and survey crop production and forestry resources. This list is by no means exhaustive and UAVs can perform many other valuable tas

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.

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.

This book introduces readers to a range of jamming principles and techniques for new radars, combining a wealth of theoretical analyses, test data, calculations, and charts. With rapid advances in military radar technology, new types of radar are constantly emerging. Therefore, there is an urgent need to carry out effective research on these new radars and to develop corresponding jamming techniques. The main topics covered include development of radar and radar countermeasures; jamming techniques for synthetic aperture radar; jamming techniques for pulse compression radar; jamming techniques for pulse Doppler radar; general jamming techniques for various radars; analysis and calculation of the effective jamming suppression zone and jamming exposure zone for radars installed on different platforms; jamming techniques for phased array radar; jamming techniques for dual (multiple) static radar; and solutions for high equivalent radiation power, high reception sensitivity, and transceiver isolation in jammer design.

The correlation of casting defects, structural characteristics and performance of castings is revealed through a range of tests. It also discusses the latest technologies and advances in this field - such as imaging the solidification process by means of synchrotron radiography, 3D computerized tomography and reconstruction of microporosity defects, analysis and diagnosis of error sources for dimension over-tolerance and adjusted pressure casting technology - which are of particular interest. Providing essential insights, the book offers a valuable guide to the design and manufacture of superalloy casting parts for aircraft engines.

Can flying be green? Everyone loves to travel, and the industry’s room for growth seems almost limitless—except that flying will soon be responsible for 19 percent of global emissions. Some people have even decided never to fly. Over the coming decades, aviation will witness more innovation than at any time since the invention of the jet engine in the 1940s, transforming the way planes are powered and the way they look. In Flying Green, Christopher de Bellaigue meets the inventors, visionaries, and entrepreneurs who are at the frontier of new technologies, from a European startup that makes fuel out of thin air, to a California firm using hydrogen to power flight, and an airship called the Flying Whale. What will it take for a new generation of travelers to fly guilt-free? This is the story of the search for a way to fly green.

Aviation remains one of the most active and challenging domains for human factors and applied psychology. Since 1981, the biennial International Symposium on Aviation Psychology (ISAP) has convened for the purposes of (a) presenting the latest research on human performance problems and opportunities within aviation systems, (b) envisioning design solutions that best utilize human capabilities for creating safe and efficient aviation systems, and (c) the bringing together of scientists, research sponsors, and operators in an effort to bridge the gap between research and application. Based upon the potential impact of emerging trends, current debates, or enduring issues presented at the 19th ISAP, select authors were invited to expand on their work following the benefit of interactions at the symposium. The authors include leading scientists, prominent researchers, and aviation operators contributing to the discussion of the most pressing technical challenges and research priorities. Visions for the incorporation of new interface technologies within next-generation cockpits, tools for future air traffic control research, neuroergonomic findings in aviation settings, and human limitations affecting safety are offered. The aim of these volumes is to report the latest findings in aviation psychology and to suggest new directions for advancing the field. FEATURES Bridges the gap between aviation psychology research and real-world challenges Includes work of the distinguished researchers and seasoned practitioners with select contributions reflecting significant developments in aviation psychology Reports on the latest findings in aviation psychology and suggests new directions for advancing the field Contains work on perceptual and cognitive influences on performance, the impact of advanced modeling techniques, and the potential of neuroergonomics

This title explores the scope of women's activities in aviation, from the time of the Wright Brothers to the present day. After highlighting the earliest female aviators, as well as the trailblazers of the inter-war period such as Amy Johnson and Amelia Earhart, the book goes on to examine the experience of women in aviation during the Second World War, including those flying with the Air Transport Auxiliary and the American Women Airforce Service Pilots. The post-war years are also covered and the title emphasises the growth in women's participation in civil and military spheres of aviation - by the last decades of the twentieth century, women had progressed even further, undertaking many of the jobs previously reserved for men, including space flight and combat flying. From the earliest women to obtain pilot's licenses to the female astronauts of the modern day, this is a concise introduction to the development of British and American women's roles in aviation.

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.

Mission Geometry: Orbit and Constellation Design and Management (OCDM) is the most complete treatment available for many elements of space mission design and astronautics.

OCDM discusses both the similarities and differences between orbit and altitude systems in terms of hardware, algorithms, design, and processing requirements. With the demand for reduced cost and the introduction of extensive on-board computing, what were once entirely separate disciplines have begun to merge. This volume will speed that process.

In all areas, OCDM is meant to be practical, with recommendations, insights, formulas, and numerical recipes based on 40 years of spaceflight experience from organizations worldwide. It is meant to be both a text and reference work that can be used by those entering the field and by senior engineers engaged in the design, analysis, construction, or on-orbit operations of orbit and attitude systems and components.

This book simulates the complete trajectories (flight and subsequent ground run) of golf shots using the aerodynamic and material properties of golf balls, and establish the significance of wind's impact on gameplay. It also presents insight into how physical parameters like launch conditions (speed, angle and spin-rate) and wind conditions affect the trajectory of a golf ball. It discusses the specific effects of wind on the flight trajectory and explore the consequences of effect of wind direction; impact of golf club selection on the wind-induced deviation; strategies and their effectiveness to counter the diversion due to wind; and the sensitivity of the trajectory to aerodynamic characteristics of golf balls. Furthermore, the impact of wind on a player's strategy is elucidated with cases studies on the renowned holes of three golf courses: (i) Hole 17, TPC Sawgrass, (ii) Hole 8, Muirfield Golf Club, and (iii) Hole 18, Pebble beach Golf links. It presents an integrated mathematical model and quantitative data on ball trajectory accompanied by insights and illustrations for players, golf-course designers, ball manufacturers, scientific community, and golf enthusiasts. This book will be useful for researchers and professionals in the fields of aerodynamics engineering, sports science and physics. Additionally, this book will be a good read for golf players and coaches, golf-course designers, as well as golf-ball manufacturers.

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?"

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!

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.

In December 1943, a top secret contract (E.24/43) was awarded to Miles Aircraft. The contract was to build the world's first supersonic jet capable of 1000mph. The only reliable source of data on supersonic objects came from the Armament Research Dept and their wind tunnel tests on ammunition. From this, Miles developed an exceptionally thin-winged, bullet-shaped aircraft. the research was inexplicably passed to the Americans in 1944. By December 1945, one prototype was virtually complete. The second, destined for an attempt at the sound barrier was 80 per cent complete. In February 1946, Capt Eric Brown was confirmed as the test pilot and October 1946 was set for the supersonic trials. However, on 12 February 1946, Miles were ordered to stop production. No plausible explanation was given for the cancellation when Britain was within six months of breaking the sound barrier. Eric Brown and others directly involved including Dennis Bancroft, the Chief Aerodynamicist on the M.52, have now come together to try and finally solve the mystery behind the cancellation.
