Book Description
Electrical vertical takeoff and landing (eVTOL) vehicles for urban air mobility (UAM) are garnering increased attention from both the automotive and aerospace industries, with use cases ranging from individual transportation, public service, cargo delivery, and more. Distributed electric propulsion systems are their main technical feature; they determine vehicle size and propulsion efficiency and provide distributed thrust to achieve attitude control. Considering the intended role of eVTOL vehicles, ducted-fan systems are ideal choice for the propulsor, as the duct provides a physical barrier between the rotating blades and the human, especially during the take-off and landing phases. Key Technology Challenges of Electric Ducted Fan Propulsion Systems for eVTOL introduces the main bottlenecks and key enablers of ducted-fan propulsion systems for eVTOL applications. Based on the introduction and discussion of these important issues, this report will help eVTOL engineers understand the key technical issues and inspire them to develop the ideal solutions that will enable eVTOL vehicle deployment for UAM operations.

Book Description
From an engineer and futurist, an impassioned account of technological stagnation since the 1970s and an imaginative blueprint for a richer, more abundant future The science fiction of the 1960s promised us a future remade by technological innovation: we’d vacation in geodesic domes on Mars, have meaningful conversations with computers, and drop our children off at school in flying cars. Fast-forward 60 years, and we’re still stuck in traffic in gas-guzzling sedans and boarding the same types of planes we flew in over half a century ago. What happened to the future we were promised? In Where Is My Flying Car?, J. Storrs Hall sets out to answer this deceptively simple question. What starts as an examination of the technical limitations of building flying cars evolves into an investigation of the scientific, technological, and social roots of the economic stagnation that started in the 1970s. From the failure to adopt nuclear energy and the suppression of cold fusion technology to the rise of a counterculture hostile to progress, Hall recounts how our collective ambitions for the future were derailed, with devastating consequences for global wealth creation and distribution. Hall then outlines a framework for a future powered by exponential progress—one in which we build as much in the world of atoms as we do in the world of bits, one rich in abundance and wonder. Drawing on years of original research and personal engineering experience, Where Is My Flying Car?, originally published in 2018, is an urgent, timely analysis of technological progress over the last 50 years and a bold vision for a better future.

Book Description
In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.

Book Description
The aviation industry is being transformed by the use of unmanned aerial vehicles, or drones – commercially, militarily, scientifically and recreationally. National regulations have generally failed to keep pace with the expansion of the fast-growing drone industry. Aviation Law and Drones: Unmanned Aircraft and the Future of Aviation traces the development of aviation laws and regulations, explains how aviation is regulated at an international and national level, considers the interrelationship between rapidly advancing technology and legislative attempts to keep pace, and reviews existing domestic and international drone laws and issues (including safety, security, privacy and airspace issues). Against this background, the book uniquely proposes a rationale for, and key provisions of, guiding principles for the regulation of drones internationally – provisions of which could also be implemented domestically. Finally, the book examines the changing shape of our increasingly busy skies – technology beyond drones and the regulation of that technology. The world is on the edge of major disruption in aviation – drones are just the beginning. Given the almost universal interest in drones, this book will be of interest to readers worldwide, from the academic sector and beyond.

Book Description
This book takes a look at fully automated, autonomous vehicles and discusses many open questions: How can autonomous vehicles be integrated into the current transportation system with diverse users and human drivers? Where do automated vehicles fall under current legal frameworks? What risks are associated with automation and how will society respond to these risks? How will the marketplace react to automated vehicles and what changes may be necessary for companies? Experts from Germany and the United States define key societal, engineering, and mobility issues related to the automation of vehicles. They discuss the decisions programmers of automated vehicles must make to enable vehicles to perceive their environment, interact with other road users, and choose actions that may have ethical consequences. The authors further identify expectations and concerns that will form the basis for individual and societal acceptance of autonomous driving. While the safety benefits of such vehicles are tremendous, the authors demonstrate that these benefits will only be achieved if vehicles have an appropriate safety concept at the heart of their design. Realizing the potential of automated vehicles to reorganize traffic and transform mobility of people and goods requires similar care in the design of vehicles and networks. By covering all of these topics, the book aims to provide a current, comprehensive, and scientifically sound treatment of the emerging field of “autonomous driving".

Book Description
What is acoustics? What is noise? How is sound measured? How can the vehicle noise be reduced using sound package treatments? Pranab Saha answers these and more in Acoustical Materials. Acoustics is the science of sound, including its generation, propagation, and effect. Although the propulsion sources of internal combustion engine (ICE) vehicles and electric motor-powered vehicles (EV) are different and therefore their propulsion noises are different, both types of vehicles have shared noise concerns: Tire and road noise Wind noise Vehicle noise and vibration issues have been there almost from the inception of vehicle manufacturing. The noise problem in a vehicle is very severe and is difficult to solve only by modifying the sources of noise and vibration. Sound package treatments address the noise and vibration issues along the path to reduce in-cabin noise. In Acoustical Materials, readers will grasp the science of reducing sound and vibration using sound absorbers, sound barriers, and vibration dampers. Sound provides information on the proper operation of the vehicle, but if unchecked, can detract from the consumer experience within the vehicle and create noise pollution outside the vehicle. Acoustical Materials provides essential information on the basics of sound, vehicle noise source, how these are measured, how vehicle owners perceive sound, and ultimately, how to solve noise problems in vehicles using sound package materials.
