Airborne Wind Energy: An Overview of the Technological Approaches (Green Energy and Technology)

by Uwe Ahrens

This book shows possible solutions to how a profitable energy supply can be implemented with almost no population resistance. Worldwide, more than 80 % of our energy needs are still covered by fossil fuels. Under these circumstances, can climate change still be stopped? Essential technologies for usage of wind energy with an emphasis on high-altitude wind utilization are presented. Airborne wind energy is one of the most promising technologies to enable a renewable energy turnaround in an economical way. The main problem of conventional renewable energy is the insufficient availability. To ensure a 100 % supply of renewable energy, enormous and very expensive storage capacities would have to be built up. How we can cover our entire energy needs (electricity, mobility and heat) in the future without fossil fuels, without risking the competitiveness of our economy, is shown in this book.

Aircraft Cryogenics (International Cryogenics Monograph Series)

by Ernst Wolfgang Stautner Kiruba S. Haran Phillip J. Ansell Constantinos Minas

This book gives a step-by-step approach to the design of a cryogenic infrastructure required for superconducting, all-electric aircraft systems which is also partially applicable to liquid hydrogen fueled subsonic and hypersonic aircraft, as well as hybrids. While there is no shortage of publications on hydrogen fueled aircraft, this book puts the past journal literature through a magnifying glass and condenses it into an engineering strategy for the next steps to enable liquid hydrogen storage and distribution in aircraft. Emphasis is placed on tank design, manufacturability, safety features, and minimum tank weight, providing a holistic focus on the logistics of hydrogen management for all major components within the aircraft as well as on future superconducting motor architecture. The intention is to fully exploit the benefits of a liquid hydrogen reservoir without any need for additional cryogenic fluids, with relevance to cooling of various superconducting components e.g., motors and superconducting cables, as well as the heat sinking of power electronics and for fueling the fuel cell stack system. A liquid hydrogen tank hold-time analysis reveals the main governing factors and describes the required efforts for minimizing onboard boil off for aircraft designs with different flight mission duration. This is followed by an outlook showing where cryotankage technology and cryogenic aircraft architecture may move within the next 20 years embedded in a green hydrogen-based economy and how basic research will need to play a major role to help us realizing these future designs by consequently eliminating whitespace within today's technology landscape. This book is also an aircraft engineering resource on composites, hydrogen properties, general aircraft materials and safety.

Aircraft Fatigue Management (SpringerBriefs in Applied Sciences and Technology)

by Lorrie Molent

Fatigue occurs under cyclic loading and can significantly degrade the operational capability and safety of metallic aircraft components and structures. This book provides summaries of some metallic aircraft structural integrity issues, innovative but established examples of maintaining operational capability—airworthiness, and assessments of safe in-service fatigue lives. These topics are based on a through-life fatigue management philosophy that ensures safe and continued operation, including during life extensions that are almost inevitably required. This philosophy is underpinned by observations of the behaviour of fatigue cracks in actual structures subjected to realistic service loading conditions. The book includes topics like aircraft design requirements, individual aircraft fatigue loads monitoring, airframe fatigue testing, sources of fatigue-nucleating discontinuities, and prediction of fatigue crack growth from these discontinuities. All these aspects contribute to discussing methods of assuring the structural integrity and operational capability of realistically cracked structures. The book also discusses the exponential behaviour of lead or dominant cracks—those leading to first failure—and the practical significance of differences between fatigue fracture topographies produced under constant amplitude and variable amplitude loading. The book can be a valuable reference for researchers and professionals interested in aircraft fatigue management and allied fields.

Airport Passenger Screening Using Backscatter X-Ray Machines: Compliance with Standards

by Committee on Airport Passenger Screening: Backscatter X-Ray Machines

Passenger screening at commercial airports in the United States has gone through significant changes since the events of September 11, 2001. In response to increased concern over terrorist attacks on aircrafts, the Transportation Security Administration (TSA) has deployed security systems of advanced imaging technology (AIT) to screen passengers at airports. To date (December 2014), TSA has deployed AITs in U. S. airports of two different technologies that use different types of radiation to detect threats: millimeter wave and X-ray backscatter AIT systems. X-ray backscatter AITs were deployed in U. S. airports in 2008 and subsequently removed from all airports by June 2013 due to privacy concerns. TSA is looking to deploy a second-generation X-ray backscatter AIT equipped with privacy software to eliminate production of an image of the person being screened in order to alleviate these concerns. This report reviews previous studies as well as current processes used by the Department of Homeland Security and equipment manufacturers to estimate radiation exposures resulting from backscatter X-ray advanced imaging technology system use in screening air travelers. Airport Passenger Screening Using Backscatter X-Ray Machines examines whether exposures comply with applicable health and safety standards for public and occupational exposures to ionizing radiation and whether system design, operating procedures, and maintenance procedures are appropriate to prevent over exposures of travelers and operators to ionizing radiation. This study aims to address concerns about exposure to radiation from X-ray backscatter AITs raised by Congress, individuals within the scientific community, and others.

Airship ROMA Disaster in Hampton Roads, The (Disaster)

by Nancy E. Sheppard

In March 1921, Major John G. Thornell and his crew were detailed to Italy to procure a new experimental airship for the United States Army Air Service. Stationed at Langley Field in Hampton, the ROMA never lived up to expectations despite being heralded as the future of military innovation. Tragically, it crashed and erupted in a ball of fire in 1922, claiming the lives of thirty-four of the brave men aboard. Author Nancy E. Sheppard reveals the forgotten, harrowing story of one of the last great airships and those who sacrificed for the promise of a new era in aviation.

Airway Chemoreceptors in Vertebrates

by Dirk Adriaensen Colin A. Nurse Giacomo Zaccone Ernest Cutz Angela Mauceri

This book provides a comprehensive and up-to-date account of the information available on the morphological, physiological and evolutionary aspects of specialized cells distributed within the epithelia of the airways in the vertebrates. A lot of work has been done on the cell and molecular biology of these cells which are regarded as as oxygen receptor neuroepithelial cells. These chemoreceptors which were conserved throughout evolution have neuroendocrine functions carrying their signals to the central nervous system. The chemoreceptor cells are sensors which detect the signal changes in the external and internal environments, and play a key role in the survival of various species. Studies addressed to the chemoreceptor cell systems in the airways are of great importance for investigating their response to changes in the oxygen and carbon dioxide concentrations in the environment since the future of the planet earth is being threatened by global warming and climate change. Praise for the book: ...This volume would be of special interest to researchers who are curious about the evolution of vertebrate respiratory control in general and the regulation of ventilation in nonmammalian vertebrates in particular. -Wayne L. Silver, Wake Forest University, in The Quarterly Review of Biology, Volume 85, Number 2

Aktuelle Ansätze zur Umsetzung der UN-Nachhaltigkeitsziele

by Walter Leal Filho

Das Buch befasst sich mit den Themen Nachhaltigkeit und Nachhaltigkeitsziele der UN. Obwohl letztere schon 2015 verabschiedet wurden und die Umsetzung bis 2030 abgeschlossen sein soll, herrscht gegenwärtig noch immer ein Mangel an Initiativen, die die Nachhaltigkeitsziele zum Thema haben. Das Buch stößt eine Diskussion darüber an, wie das Thema Nachhaltigkeit ganzheitlich in der Lehre, Forschung, Wirtschaft und Gesellschaft eingeführt und bearbeitet werden kann. Eine Vielzahl unterschiedlicher Disziplinen, von den Sozial- und Wirtschaftswissenschaften über Mode- und Kunst- sowie Umweltwissenschaften bis hin zu den Sprach- und Medienwissenschaften tragen zu dem Werk bei. Im Fokus des Buchs stehen die Mittel und Wege, mit denen das Engagement der Hochschulen und Nichtregierungsorganisationen in den globalen Bemühungen zur Umsetzung der Nachhaltigkeitsziele zusammengeführt wird. Der Band vereinigt viele Erfahrungen und Fallstudien, die zur Weiterentwicklung des Themas „Umsetzung der SDGs“ beitragen.

Akzeptanz von In-vitro-Fleisch und pflanzenbasierten Fleischersatzprodukten in Deutschland: Eine Anwendung der Theorie der kognitiven Hierarchie (BestMasters)

by Maresa Anna Temmen

Maresa Anna Temmen untersucht auf Grundlage der Theorie der kognitiven Hierarchie die Konsumbereitschaft für In-vitro-Fleisch und pflanzenbasierte Fleischersatzprodukte in Deutschland. Hierzu werden unter anderem ernährungspsychologische Einflussfaktoren genutzt, die sich auf moralische und ideologische Einstellungen zum Fleischkonsum beziehen. Die Ergebnisse der quantitativen Online-Fragebogenstudie zeigen, dass die Konsumbereitschaft für In-vitro-Fleisch und pflanzenbasierte Fleischersatzprodukte in der deutschen Bevölkerung relativ hoch ist und stützen die Theorie der kognitiven Hierarchie: Entsprechend können eine universalistisch geprägte Wertestruktur, eine geringe soziale Dominanzorientierung, eine geringe Ausprägung von Speziesismus und karnistischer Dominanz sowie eine geringe Unterstützung von Rechtfertigungsstrategien für den Konsum von Fleisch Gründe für eine hohe Konsumbereitschaft von In-vitro-Fleisch und pflanzenbasierten Fleischalternativen sein. Die Studie zeigt, dass tiefliegende Persönlichkeitsvariablen wie Werte und Wertorientierungen einen Einfluss auf spezifischere Einstellungen nehmen, die wiederum einen Einfluss auf die Konsumbereitschaft von Fleischalternativen haben.
