Although the United States Air Force was founded upon strategic bombardment theory and advocacy, the service has traditionally had tremendous difficulty in obtaining the adequate funding for bombers that it requires to fulfill its mandate. For more than 45 years, senior Air Force leaders, both military and civilian, have struggled to convince decision-makers in the White House and in Congress that modern manned bomber forces were needed, acceptable, and affordable. In this study, Donnini produces one of the most exhaustive analyses ever undertaken of Congressional subcommittee decision-making in the funding of defense procurement initiatives. He concludes that no program achieved measurable success of deployment with the original force structure requested; and only two, the B-1B and B-2A, received approval to acquire lesser numbers of aircraft for operational use. Donnini found that an important part of each new bomber program appeared to be funding support through federal appropriations. If the right amounts were appropriated, the programs survived; if lesser amounts were given, chances for program failure were good; however, was funding support the deciding factor? This book used multiple case studies and the unorthodox methodology of applied content analysis of Congressional budget hearings to examine Air Force efforts to fund the most recent main bombers it sought (the B-70, B-1A, B-1B, and B-2A) and to determine measurements of success. The author's findings have implications concerning the way the United States handles procurement initiatives for major new weapon systems considered fundamental necessities for national defense.

It explains exactly how to design a laser communication system and its potential applications.

These three volumes entitled Advances in Hypersonics contain the Proceedings of the Second and Third Joint US/Europe Short Course in Hypersonics which took place in Colorado Springs and Aachen. The Second Course was organized at the US Air Force Academy, USA in January 1989 and the Third Course at Aachen, Germany in October 1990. The main idea of these Courses was to present to chemists, com puter scientists, engineers, experimentalists, mathematicians, and physicists state of the art lectures in scientific and technical dis ciplines including mathematical modeling, computational methods, and experimental measurements necessary to define the aerothermo dynamic environments for space vehicles such as the US Orbiter or the European Hermes flying at hypersonic speeds. The subjects can be grouped into the following areas: Phys ical environments, configuration requirements, propulsion systems (including airbreathing systems), experimental methods for external and internal flow, theoretical and numerical methods. Since hyper sonic flight requires highly integrated systems, the Short Courses not only aimed to give in-depth analysis of hypersonic research and technology but also tried to broaden the view of attendees to give them the ability to understand the complex problem of hypersonic flight. Most of the participants in the Short Courses prepared a docu ment based on their presentation for reproduction in the three vol umes. Some authors spent considerable time and energy going well beyond their oral presentation to provide a quality assessment of the state of the art in their area of expertise as of 1989 and 1991."

The inspiring story of a pathbreaking 1919 flight and the courageous fliers who risked their lives to make aviation history.

In 1919, in Newfoundland, four teams of aviators came from Britain to compete in “the Big Hop”: an audacious race to be the first to fly, nonstop, across the Atlantic Ocean. One pair of competitors was forced to abandon the journey halfway, and two pairs never made it into the air. Only one team, after a death-defying sixteen-hour flight, made it to Ireland.

Celebrated on both continents, the transatlantic contest offered a surge of inspiration―and a welcome distraction―to a public reeling from the Great War and the influenza pandemic. But the seven airmen who made the attempt were quickly forgotten, their achievement overshadowed by the solo Atlantic flights of Charles Lindbergh and Amelia Earhart years later. In The Big Hop, David Rooney grants the pioneering aviators of 1919 the spotlight they deserve. From Harry Hawker, the pilot who as a young man had watched Houdini fly over his native Australia, to the engineer Ted Brown, a US citizen who joined the Royal Flying Corps, Rooney traces the lives of the unassuming men who performed extraordinary acts in the sky.

Mining evocative first-person accounts and aviation archives, Rooney also follows the participants’ journeys: learning to fly on flimsy airplanes made of timber struts and varnished fabric; surviving the bloodiest war that Europe had ever yet seen; and battling faulty coolant systems, severe storms, and extreme fatigue while attempting the Atlantic. Rooney transports readers to the world in which the great contest took place, and traces the rise of aviation to its daredevil peak in the early decades of the twentieth century. Recounting a deeply moving adventure, The Big Hop explores why flights like these matter, and why we take to the skies.

This thesis describes the development of a new technique to solve an important industrial inspection requirement for a high-value jet-engine component. The work - and the story told in the thesis - stretches all the way from the fundamentals of wave propagation in anisotropic material and ultrasonic array imaging through to device production and site trials. The book includes a description of a new method to determine crystallographic orientation from 2D ultrasonic array data. Another new method is described that enables volumetric images of an anisotropic material to be generated from 2D ultrasonic array data, based on measured crystallographic orientation. After extensive modeling, a suitable 2D array and deployment fixtures were manufactured and tested on in situ turbine blades in real engines. The final site trial indicated an order of magnitude improvement over the best existing technique in the detectability of a certain type of root cracking. The Development of a 2D Ultrasonic Array Inspection for Single Crystal Turbine Blades should be an inspiration for those starting out on doctoral degrees as it shows the complete development cycle from basic science to industrial usage.

The book specifically looks at trends in algorithm research, human computer interface, network-based computing, surface modeling and grid generation and computer hardware and architecture. The book provides a good overview of the current state-of-the-art and provides guidelines for future research directions. The book is intended for computational scientists active in the field and program managers making strategic research decisions.

From the Foreword by Captain Daniel Maurino, ICAO: '...Air Traffic Control...will remain a technology-intensive system. People (controllers) must harmoniously interact with technology to contribute to achieve the aviation system's goals of safe and efficient transportation of passengers and cargo...This book...considers human error and human factors from a contemporary and operational perspective and discusses the parts as well as the whole...I hope you enjoy reading it as much as I did.' The motivation for writing this book comes from the author's long standing belief that the needs of Air Traffic Service personnel are inadequately represented in the aviation literature. There are few references to air traffic control in many of the books written for pilots and about pilots and this is also observed at the main international conferences. In line with the ICAO syllabus for human factors training for air traffic controllers, the book covers the main issues in air traffic control, with regard to human performance: physiology including stress, fatigue and shift work problems; psychology with emphasis on human error and its management, social psychology including issues of communication and working in teams, the environment including ergonomic principles and working with new technologies and hardware and software issues including the development of documentation and procedures and a study of the changes brought about by advanced technologies. Throughout the text there are actual examples taken from the air traffic control environment to illustrate the issues discussed. A full bibliography is included for those who want to read beyond these issues. It has been written for all in air traffic services, from ab initio to the boardroom; it is important that the men and women in senior management positions have some knowledge and awareness of the fundamental problems that limit and enhance human performance.

The major changes taking place in technology have some of the greatest effect in the world of aviation. Yet, in an industry which started with the concept of 'open skies', each sector has traditionally developed on its own and adjusted to developments in other areas as and when required. The need for integration is particularly important as the skies become increasingly crowded. More intense commercialization dramatically increases the interlocking between technological developments and the size of the financial investments required. For maximum efficiency the aviation system thus has to develop as an integrated whole with a greater awareness of events in other sectors. This book is intended to meet this requirement by addressing the breadth and depth of the aviation system and looking at some areas where significant advances are happening. While following the processes of development, the reader will see where the results might lead in the new century. Its three parts concentrate on areas of great significance - in integration as well as in technological progress - especially for their impact on human and social aspects. The editor and the invited contributors are amongst the foremost experts, researchers and industry leaders in their fields in the global aviation community, many with hands-on experience of massive change. The intended readership includes those who are moving into management functions in air traffic management, airplane manufacturing and airline operations; in training centres, colleges and institutions.

This textbook provides a coherent and structured overview of fluid mechanics, a discipline concerned with many natural phenomena and at the very heart of the most diversified industrial applications and human activities. The balance between phenomenological analysis, physical conceptualization and mathematical formulation serve both as a unifying educational marker and as a methodological guide to the three parts of the work. The thermo-mechanical motion equations of a homogeneous single-phase fluid are established, from which flow models (perfect fluid, viscous) and motion classes (isovolume, barotropic, irrotational, etc.) are derived. Incompressible, potential flows and compressible flows, both in an isentropic evolution and shock, of an ideal inviscid fluid are addressed in the second part. The viscous fluid is the subject of the last one, with the creeping motion regime and the laminar, dynamic and thermal boundary layer. Historical perspectives are included whenever they enrich the understanding of modern concepts. Many examples, chosen for their pedagogical relevance, are dealt with in exercises. The book is intended as a teaching tool for undergraduate students, wishing to acquire a first command of fluid mechanics, as well as graduates in advanced courses and engineers in other fields, concerned with completing what is sometimes a scattered body of knowledge.

Questions concerning safety in aviation attract a great deal of attention, due to the growth in this industry and the number of fatal accidents in recent years. The aerospace industry has always been deeply concerned with the permanent prevention of accidents and the conscientious safeguarding of all imaginable critical factors surrounding the organization of processes in aeronautical technology. However, the developments in aircraft technology and control systems require further improvements to meet future safety demands.
This book embodies the proceedings of the 1997 International Aviation Safety Conference, and contains 60 talks by internationally recognized experts on various aspects of aviation safety. Subjects covered include:
Human interfaces and man-machine interactions; Flight safety engineering and operational control systems; Aircraft development and integrated safety designs; Safety strategies relating to risk insurance and economics; Corporate aspects and safety management factors --- including airlines services and airport security environment.

The book includes the research papers presented in the final conference of the EU funded SARISTU (Smart Intelligent Aircraft Structures) project, held at Moscow, Russia between 19-21 of May 2015. The SARISTU project, which was launched in September 2011, developed and tested a variety of individual applications as well as their combinations. With a strong focus on actual physical integration and subsequent material and structural testing, SARISTU has been responsible for important progress on the route to industrialization of structure integrated functionalities such as Conformal Morphing, Structural Health Monitoring and Nanocomposites. The gap- and edge-free deformation of aerodynamic surfaces known as conformal morphing has gained previously unrealized capabilities such as inherent de-icing, erosion protection and lightning strike protection, while at the same time the technological risk has been greatly reduced. Individual structural health monitoring techniques can now be applied at the part-manufacturing level rather than via extending an aircraft's time in the final assembly line. And nanocomposites no longer lose their improved properties when trying to upscale from neat resin testing to full laminate testing at element level. As such, this book familiarizes the reader with the most significant develo pments, achievements and key technological steps which have been made possible through the four-year long cooperation of 64 leading entities from 16 different countries with the financial support of the European Commission.

J.L. Burch*V. Angelopoulos Originally published in the journal Space Science Reviews, Volume 141, Nos 1-4, 1-3. DOI: 10.1007/s11214-008-9474-5 (c) Springer Science+Business Media B.V. 2008 The Earth, like all the other planets, is continuously bombarded by the solar wind, which is variable on many time scales owing to its connection to the activity of the Sun. But the Earth is unique among planets because its atmosphere, magnetic eld, and rotation rates are each signi cant, though not dominant, players in the formation of its magnetosphere and its reaction to solar-wind inputs. An intriguing fact is that no matter what the time scale of solar-wind variations, the Earth's response has a de nite pattern lasting a few hours. Known as a magnetospheric substorm, the response involves a build-up, a crash, and a recovery. The build-up (known as the growth phase) occurs because of an interlinking of the geom- netic eld and the solar-wind magnetic eld known as magnetic reconnection, which leads to storage of increasing amounts of magnetic energy and stress in the tail of the mag- tosphere and lasts about a half hour. The crash (known as the expansion phase) occurs when the increased magnetic energy and stresses are impulsively relieved, the current system that supports the stretched out magnetic tail is diverted into the ionosphere, and bright, dynamic displays of the aurora appear in the upper atmosphere. The expansion and subsequent rec- ery phases result from a second magnetic reconnection event that decouples the solar-wind and geomagnetic elds.

This book provides a single comprehensive resource that reviews many of the current aircraft flight control programmes from the perspective of experienced practitioners directly involved in the projects. Each chapter discusses a specific aircraft flight programme covering the control system design considerations, control law architecture, simulation and analysis, flight test optimization and handling qualities evaluations. The programmes described have widely exploited modern interdisciplinary tools and techniques and the discussions include extensive flight test results. Many important `lessons learned' are included from the experience gained when design methods and requirements were tested and optimized in actual flight demonstration.

This book highlights the capabilities and limitations of radar and air navigation. It discusses issues related to the physical principles of an electromagnetic field, the structure of radar information, and ways to transmit it. Attention is paid to the classification of radio waves used for transmitting radar information, as well as to the physical description of their propagation media. The third part of the book addresses issues related to the current state of navigation systems used in civil aviation and the prospects for their development in the future, as well as the history of satellite radio navigation systems. The book may be useful for schoolchildren, interested in the problems of radar and air navigation.

Franz Georg Hey summarises the development and testing of a micro-Newton thrust balance, as well as the downscaling of a High Efficiency Multistage Plasma Thruster to micro-Newton thrust levels. The balance is tailored to fully characterise thruster candidates for the space based gravitational wave detector LISA. Thus, thrust noise measurements in sub-micro-Newton regime can be performed in the overall LISA bandwidth. The downscaled thruster can be operated down to serval tens of micro-Newton with a comparably high specific impulse. About the Author Franz Georg Hey works as mechanical, thermal, propulsion architect and technical lead of the micro-Newton propulsion laboratory of Europe's leading air and spacecraft manufacturer. The author is participating on major programmes for future satellite and electric propulsion development. The author's research is performed in close collaboration with the Dresden University of Technology, the University of Bremen and the DLR Bremen.
