Facing the Heat Barrier


Book Description

This volume from The NASA History Series presents an overview of the science of hypersonics, the study of flight at speeds at which the physics of flows is dominated by aerodynamic heating. The survey begins during the years immediately following World War II, with the first steps in hypersonic research: the development of missile nose cones and the X-15; the earliest concepts of hypersonic propulsion; and the origin of the scramjet engine. Next, it addresses the re-entry problem, which came to the forefront during the mid-1950s, showing how work in this area supported the manned space program and contributed to the development of the orbital shuttle. Subsequent chapters explore the fading of scramjet studies and the rise of the National Aerospace Plane (NASP) program of 1985–95, which sought to lay groundwork for single-stage vehicles. The program's ultimate shortcomings — in terms of aerodynamics, propulsion, and materials — are discussed, and the book concludes with a look at hypersonics in the post-NASP era, including the development of the X-33 and X-34 launch vehicles, further uses for scramjets, and advances in fluid mechanics. Clearly, ongoing research in hypersonics has yet to reach its full potential, and readers with an interest in aeronautics and astronautics will find this book a fascinating exploration of the field's history and future.







US Hypersonic Research and Development


Book Description

An essential new account of some of the most valuable research and development in international military history. Roy F. Houchin II shows how the roots of US Air Force hypersonic research and development are grounded in Army Air Force General Henry H. 'Hap' Arnold's identification of the need for advanced airpower weapon systems to meet the anticipated postwar enemy threat. The technology for a smooth transition to military spaceflight seemed within reach when Bell Aircraft Corporation executive Walter Dornberger (the former commander of Nazi Germany's V-2 rocket research) made an unsolicited proposal to William E. Lamar (the chief of Wright Aeronautical Development Center's New Development Office of the Bomber Aircraft Division at Wright-Patterson AFB, OH) for a hypersonic boost-glide weapon system. Visionaries like Arnold, Dornberger, and Lamar believed a hypersonic boost-glider would represent the ultimate expression of the US Air Force's doctrine by performing strategic bombardment and reconnaissance more successfully any other type of vehicle. As this aspiration reached maturity in Dyna-Soar, the service's leadership never gave up their beliefs. This book shows how the struggle to persuade the secretary of defence and his advisors, who did not share the Air Force's vision for a military spaceplane, illustrates the ebb and flow of an advanced technology program and its powerful legacy within American society.
