Book Description
For a while, it seemed the series of experimental aircraft sponsored by the U. S. government had run its course. Between the late 1940s and the late 1970s, almost thirty designations had been allocated to aircraft meant to explore new flight regimes or untried technologies. Then, largely, it ended. But there was a resurgence in the mid- to late1990s, and as we enter the fourth year of the new millennia, the designations are up to X-50. Many have a misconception that X-vehicles have always explored the high-speed and high-altitude flight regimes—something popularized by Chuck Yeager in the original X-1 and the exploits of the twelve men that flew the X-15. Although these flight regimes have always been in the spotlight, many others have been explored by X-vehicles. The little Bensen X-25 never exceeded 85 mph, and others were limited to speeds of several hundred mph. There has been some criticism that the use of X designations has been corrupted somewhat by including what are essentially prototypes of future operational aircraft, especially the two JSF demonstrators. But this is not new—the X-11 and X-12 from the 1950s were going to be prototypes of the Atlas intercontinental ballistic missile, and the still-born Lockheed X-27 was always intended as a prototype of a production aircraft. So although this practice does not represent the best use of “X” designations, it is not without precedent.

Book Description
In the aviation field there is great interest in high-speed vehicle design. Hypersonic vehicles represent the next frontier of passenger transportation to and from space. However, several design issues must be addressed, including vehicle aerodynamics and aerothermodynamics, aeroshape design optimization, aerodynamic heating, boundary layer transition, and so on. This book contains valuable contributions focusing on hypervelocity aircraft design. Topics covered include hypersonic aircraft aerodynamic and aerothermodynamic design, especially aeroshape design optimization, computational fluid dynamics, and scramjet propulsion. The book also discusses high-speed flow issues and the challenges to achieving the dream of affordable hypersonic travel. It is hoped that the information contained herein will allow for the development of safe and efficient hypersonic vehicles.

Book Description
In 2018 almost half of all vehicles made in North America were produced at foreign-owned plants, and the sector was on track to monopolize the market. Despite this, the industry has been overlooked compared with its domestic counterpart, both in scholarship and popular memory. Redressing this neglect, America’s Other Automakers provides a new history of the foreignowned auto sector, the first to extensively draw on archival sources and to articulate the human agency of participants, including workers, managers, and industry recruiters. Timothy J. Minchin challenges the view that the industry’s growth primarily reflected incentives, stressing human agency and the complexity of individual stories instead. Deeply human in its approach, the book also explores the industry’s impact on grassroots communities, showing that it had more costs than supporters acknowledged. Drawing on a wide range of primary and secondary sources, America’s Other Automakers uncovers significant tensions over unionization, reports of discriminatory hiring, and unease about the industry’s rapid growth, critically exploring seven large assembly facilities and their impact on the communities in which they were built.

Book Description
A Smithsonian Best History Book of the Year Winner of the Littleton-Griswold Prize Winner of the Ralph Waldo Emerson Award Winner of the Order of the Coif Award Winner of the Sidney M. Edelstein Prize Winner of the David J. Langum Sr. Prize in American Legal History Winner of the Berkshire Conference of Women Historians Book Prize “From traffic stops to parking tickets, Seo traces the history of cars alongside the history of crime and discovers that the two are inextricably linked.” —Smithsonian When Americans think of freedom, they often picture the open road. Yet nowhere are we more likely to encounter the long arm of the law than in our cars. Sarah Seo reveals how the rise of the automobile led us to accept—and expect—pervasive police power, a radical transformation with far-reaching consequences. Before the twentieth century, most Americans rarely came into contact with police officers. But in a society dependent on cars, everyone—law-breaking and law-abiding alike—is subject to discretionary policing. Seo challenges prevailing interpretations of the Warren Court’s due process revolution and argues that the Supreme Court’s efforts to protect Americans did more to accommodate than limit police intervention. Policing the Open Road shows how the new procedures sanctioned discrimination by officers, and ultimately undermined the nation’s commitment to equal protection before the law. “With insights ranging from the joy of the open road to the indignities—and worse—of ‘driving while black,’ Sarah Seo makes the case that the ‘law of the car’ has eroded our rights to privacy and equal justice...Absorbing and so essential.” —Paul Butler, author of Chokehold “A fascinating examination of how the automobile reconfigured American life, not just in terms of suburbanization and infrastructure but with regard to deeply ingrained notions of freedom and personal identity.” —Hua Hsu, New Yorker
