The author offers practical coverage of vibration stresses and stress-induced displacements, isolation of sensitive components, and evaluation of elastic instability, fatigue and fracture as potential failure modes that arise in mechanical designs and aerospace. The approach taken is particularly useful in the early design stage - the physical problem is defined via known parameters, and a methodology is given for determining the unknown quantities and relating them to specified limiting values and failure modes to obtain an acceptable design. Many of the calculations can be performed on a PC or programmable calculator.

This book presents an isospectral approach for several important mechanical vibrating systems. Discrete and continuous isospectral systems are discussed using a simple multi-degree of freedom spring-mass system followed by illustration of isospectral beams and their solution through evolutionary computing. Next, it addresses axially loaded Euler-Bernoulli beams and aims to find isospectral counterparts of these systems. The practical application of these isospectral systems for vibration testing and for finding new closed form solutions is discussed. A considerable part of the book is devoted to isospectral rotating beams and their non-rotating analogs including Rayleigh beams. Aimed at researchers and graduate students in mechanical; aerospace; civil; automotive; ocean engineering especially mechanical vibrations, this monograph: Discusses isospectral vibrating systems to aid vibration testing and computational analysis Explores isospectral analogs between rotating and non-rotating structures Provides simpler isospectral beams for vibration testing and for 3D printing Uses firefly optimization method and electromagnetism inspired optimization method to find isospectral systems Shows the use of isospectral systems to find new closed form solutions using an indirect approach

This book studies the dynamics of 2D objects moving through turbulent fluids. It examines the decay of turbulence over extended time scales, and compares the dynamics of non-spherical particles moving through still and turbulent fluids. The book begins with an introduction to the project, its aims, and its relevance for industrial applications. It then discusses the movement of planar particles in quiescent fluid, and presents the numerous methodologies used to measure it. The book also presents a detailed analysis of the falling style of irregular particles, which makes it possible to estimate particle trajectory and wake morphology based on frontal geometry. In turn, the book provides the results of an analysis of physically constrained decaying turbulence in a laboratory setting. These results suggest that large-scale cut-off in numerical simulations can result in severe bias in the computed turbulent kinetic energy for long waiting times. Combining the main text with a wealth of figures and sketches throughout, the book offers an accessible guide for all engineering students with a basic grasp of fluid mechanics, while the key findings will also be of interest to senior researchers.

The Space Shuttle tells the story of NASA's amazing Space Shuttle program and its 140 space flights (135 missions, plus five Approach and Landing Tests) in a uniquely designed and covetable way. The Space Shuttle program's first free flight test was taken on August 12, 1977. Its first official mission was launched on April 12, 1981. Its final mission and flight was taken on July 8, 2011. The program's six orbiter vehicles are Enterprise, Columbia, Challenger, Discovery, Atlantis, and Endeavour. Each mission has its own fascinating story, and The Space Shuttle retells these stories, in chronological order, through incredible photos taken by NASA photojournalists, fine art photographers, and the astronauts themselves. Each image is accompanied by a short text that includes quick facts such as crew members, launch date, and landing date, as well as a short overview of highlights and purpose. For example, STS-78's mission was to study circadian rhythms in space; STS-41G's mission was to take photographs in-flight, seen in the IMAX movie The Dream Is Alive; and famously, the first untethered space walk, taken by astronaut Bruce McCandless on STS-41B using a self-propelled backpack unit (called a Man Maneuvering Unit [MMU]), allowed astronauts to capture satellites for retrieval and repair and for the planned construction of what became the International Space Station (ISS). Prior to this mission, astronauts were attached to the shuttle with safety lines. The photo of McCandless floating above Earth's surface is one of the most celebrated and famous space photographs ever. These are just a few of the 140 stories Miller tells in this beautiful volume.

Revised and updated in its fifth edition, this internationally renowned and respected book provides the essentials to understanding all areas of airline finance. Designed to address each of the distinct areas of financial management in an air transport industry context, it also shows how these fit together, while each chapter and topic - for example, aircraft leasing - provides a detailed resource that can also be consulted separately. Supported at each stage by practical airline examples and recent data, Airline Finance examines the financial trends and longer term prospects for the airline industry as a whole, contrasting the developments for the major regions and airlines together with critical discussion of key issues that affect the industry as a whole. Important techniques in financial analysis are applied to the airlines as well as their investors such as banks and other financial institutions. Thoroughly amended and updated throughout, and expanded with the addition of two new chapters, the fifth edition reflects the many developments that have affected the industry, such as the impacts of the banking and sovereign debt crises on the airline industry, signs of re-nationalisation of airlines that have emerged in Europe, and the substantial changes that have occurred in connection with rating agencies and LIBOR. New start-ups and bankruptcies are covered for the first time in a new chapter, joined by airline mergers and acquisitions (M&A), both playing a role in airline concentration. Reflecting their status as a permanent feature, fuel hedging and fuel surcharges now also have their own chapter. The medium- to long-term future in terms of further concentration and government intervention (or the lack of it) and a shift in aircraft financing towards capital markets are discussed in the final chapter. The book is written for employees of airlines, airports and their suppliers, and investment bank and other analysts. It is also popular for use by universities and in-house courses on air transport management, within both academia and industry.

Predating the invention of the helicopter by two decades, the Autogiro was the world's first rotary-wing aircraft. The helicopter had the advantageous ability to rise straight up, while the Autogiro/gyroplane could only taxi. Yet the gyroplane was safer and more stable; both aircraft should have had value in market. Why did the helicopter survive and prosper, while the Autogiro became a nearly forgotten historical footnote? Why didn't the Autogiro catch on, and why is it being revived today? This is the first book to tell the fascinating 80-year history of today's gyroplane and its antecedent, the Autogiro. Charnov explains that the near-eclipse of the Autogiro was caused by a potent combination of bad luck, the impact of the Great Depression and World War II, and egregious business decisions. Only by understanding the amazing manner in which this aviation technology has persisted and evolved can one fully understand the basis for its future. In contrast to the fate of the Autogiro, the gyroplane's unfolding story is characterized by successful business models, effective decision making, and the emergence of cutting-edge technology. The survival of the gyroplane may be a paradigm for the persistence of earlier, less complex technologies, and its future relies on grasping its colorful history.

This unique book expands the contribution of aviation psychology and human factors to the aviation industry within the Asia Pacific region, with participation from many other parts of the globe, and key local and international experts, developing the safety, efficiency and viability of the industry.

This is the formal refereed proceedings of The Fifth Australian Aviation Psychology Symposium, Manly Beach, Sydney 2000. The symposium had a diverse range of contributions and Development Workshops, bringing together practitioners from aviation psychology and human factors, flight operations management, safety managers, pilots, cabin crew, air traffic controllers, engineering and maintenance personnel, air safety investigators, staff from manufacturers and regulatory bodies, and applied aviation industry researchers and academics. This book will be of interest to anyone involved in human factors, safety systems or aviation psychology within both the civil and military aviation industry.

During the 1960s - in the midst of its retreat from empire - the British government had to grapple with complex political and military problems in order to find a strategic defence policy that was both credible and affordable. Addressing what was perhaps the most contentious issue within those debates, this book charts the arguments that raged between supporters of a land based air power strategy, and those who favoured aircraft carriers. Drawing upon a wealth of previously classified documents, the book reveals how the Admiralty and Air Ministry became interlocked in a bitter political struggle over which of their military strategies could best meet Britain's future foreign policy challenges. Whilst the broad story of this inter-service rivalry is well known - the Air Force's proposal for a series of island based airfields, and the Navy championing of a small number of expensive but mobile aircraft carriers - the complexity and previous lack of archival sources means that it has, until now, only ever been partially researched and understood. Former studies have largely focused on the cancellation of the CVA-01 carrier programme, and offered little depth as regards the Royal Air Force perspectives. Given that this was a two-Service rivalry, which greatly influenced many aspects of British foreign and defence policy decisions of the period, this book presents an important and balanced overview of the complex issues involved. Through this historical study of the British debate about maritime air power and strategic alternatives in the 1960s, the detailed arguments used for and against both alternatives demonstrate clear relevance to both historical and contemporary conceptual debates on carrier forces and land-based air power. Both from military strategy and inter-service relationship perspectives, contemporary Britain and many other nations with maritime forces may learn much from this historical case.

Strategic airline alliances are an important topic in airline management today, stimulated by poor access of international airlines to large domestic markets such as the USA and EU and the increasing importance of network scope. Outright mergers of international airlines have proved to be difficult for political, cultural and legal reasons, making alliances the best available form to strengthen strategic positions and streamline networks. However, there are a number of difficulties associated with an alliance such as long-term stability, political climate, cultural conflict and how much capital alliance partners should sink into the integration. The main purpose of the book is to convey in an accessible form to a wide audience, the results of recent academic research on strategic airline alliances. The authors systematically cover: policy, regulation and consumer issues; management, marketing and strategic issues; the mechanics of airline alliances; the airline alliance group as an organisation in its own right; different forms of alliances and clusters; success and failure factors of airline alliances. The book successfully: - provides an analytical framework for understanding the dynamics of airline alliance groups - examines both the level of the individual airline and the alliance group itself - applies recent insights from organisation theory. The readership includes airline managers, policy-makers, academic researchers and others interested in evolving multilateral alliances. It can also be used as a course book both in aviation management training and in more general modules on alliances for advanced students in air transport management.

Human error is now the main cause of aircraft accidents. However, in many cases the pilot simply falls into a trap that has been left for him/her by the poor design of the flight deck. This book addresses the human factors issues pertinent to the design of modern flight decks. Comprising of invited chapters from internationally recognised experts in human factors and flight deck design, contributions span the world of industry, government research establishments and academia. The book brings together the practical experience of professionals across the human factors and flight deck design disciplines to provide a single, all-encompassing volume. Divided into two main parts, part one of the book examines: the benefits of human engineering; flight deck design process; head down display design; head-up display design; auditory warning systems; flight control systems, control inceptors and aircraft handling qualities; flight deck automation; and human-computer interaction on the flight deck and anthropometrics for flight deck design. Part two is concerned with flight deck evaluation - the human factors evaluation of flight decks; human factors in flight test and the regulatory viewpoint Of interest to all human factors professionals operating in high technology, high-risk dynamic industries as well as those engaged directly in aerospace activities, the book will also be of key importance to engineers with an interest in human factors for flight deck design, academics and third year and post-graduate human factors/ergonomics and psychology students.
