This book reviews the remarkable efforts to develop a new aircraft configuration known as the Blended Wing-Body (BWB). Responding to a challenge from NASA, McDonnell Douglas Corporation initiated studies in the early 1990s to determine if this new configuration could bring about significant advantages over conventional sweptwing, streamlined tube, and swept-tail designs. Challenges were identified and this information allowed the design and construction of two small-scale demonstrators: the X-48B. After McDonnell Douglas' merger with Boeing, the X-48B flew 92 test flights before modification into the X-48C, which in turn flew 30 flights under the auspices of NASA's Environmentally Responsible Aviation Program.

The Wind and Beyond: A Documentary Journey Into the History of Aerodynamics in America, V. 2 by James R. Hansen,National Aeronautics and Space Administration Pdf
The airplane ranks as one of history's most ingenious and phenomenal inventions. It has surely been one of the most world changing. How ideas about aerodynamics first came together and how the science and technology evolved to forge the airplane into the revolutionary machine that it became is the epic story told in this six-volume series, The Wind and Beyond: A Documentary Journey through the History of Aerodynamics in America. Following up on Volume I's account of the invention of the airplane and the creation of the original aeronautical research establishment in the United States, Volume II explores the airplane design revolution of the 1920s and 1930s and the quest for improved airfoils. Subsequent volumes cover the aerodynamics of airships, flying boats, rotary-wing aircraft, breaking the sound barrier, and more.

Elements of Vorticity Aerodynamics by James C. Wu Pdf
This book opens with a discussion of the vorticity-dynamic formulation of the low Mach number viscous flow problem. It examines the physical aspects of the velocity and the vorticity fields, their instantaneous relationship, and the transport of vorticity in viscous fluids for steady and unsteady flows. Subsequently, using classical analyses it explores the mathematical aspects of vorticity dynamics and issues of initial and boundary conditions for the viscous flow problem. It also includes the evolution of the vorticity field which surrounds and trails behind airfoils and wings, generalizations of Helmholtz’ vortex theorems and the Biot-Savart Law. The book introduces a theorem that relates the aerodynamic force to the vorticity moment and reviews the applications of the theorem. Further, it presents interpretations of the Kutta-Joukowski theorem and Prandtl’s lifting line theory for vorticity dynamics and discusses wake integral methods. The virtual-mass effect is shown to be the seminal event in unsteady aerodynamics and a simple approach for evaluating virtual-mass forces on the basis of vorticity dynamics is presented. The book presents a modern viewpoint on vorticity dynamics as the framework for understanding and establishing the fundamental principles of viscous and unsteady aerodynamics. It is intended for graduate-level students of classical aerodynamics and researchers exploring the frontiers of fully unsteady and non-streamlined aerodynamics.
Beyond Uranus is the first of a trilogy of four or more books telling the ripping space yarns and illuminating times of an always late to work teacher and heroic on-line gamer. The wrong kind of life, in the wrong kind of job, leads Roy to emotionally subsist on lager, pizza and on-line gaming. A fantastical opportunity presents him with a chance to boldly go, where others have trod before. Joining the crew of a mysterious Earth Station, Roy becomes a space pilot working for the galactic ‘UN’ shielding the Earth from an inappropriate first contact. With a group of friends and an extraordinary personal computer he explores forbidden areas of the Station and excessively discovers that an alcohol ban doesn’t cover the whole of it. Meanwhile, rogue pilot Dr. John D’Eath has iniquitous plans to kill Roy but is thrown off the station when his plot to frame him for an attack backfires. And Roy finds the love of his life when he meets a beautiful red-head and loves the tinge of ginge in her. One day Roy attempts to shunt a mysterious freighter away from Earth and his indestructible ship is promptly destroyed, with himself being captured. Rescue comes from the person he least expects, which leads to him discover some shocking, hidden truths. Some 85,000 words help tell this humorous tale, peppered with bar-room philosophy and sprinkled with adult language.
The X-31 Enhanced Fighter Maneuverability Demonstrator was unique among experimental aircraft. A joint effort of the United States and Germany, the X-31 was the only X-plane to be designed, manufactured, and flight tested as an international collaboration. It was also the only X-plane to support two separate test programs conducted years apart, one administered largely by NASA and the other by the U.S. Navy, as well as the first X-plane ever to perform at the Paris Air Show. Flying Beyond the Stall begins by describing the government agencies and private-sector industries involved in the X-31 program, the genesis of the supermaneuverability concept and its initial design breakthroughs, design and fabrication of two test airframes, preparation for the X-31's first flight, and the first flights of Ship #1 and Ship #2. Subsequent chapters discuss envelope expansion, handling qualities (especially at high angles of attack), and flight with vectored thrust. The book then turns to the program's move to NASA's Dryden Flight Research Center and actual flight test data. Additional tasking, such as helmet-mounted display evaluations, handling quality studies, aerodynamic parameter estimation, and a "tailless" study are also discussed.The book describes how, in the aftermath of a disastrous accident with Ship #1 in 1995, Ship #2 was prepared for its outstanding participation in the Paris Air Show. The aircraft was then shipped back to Edwards AFB and put into storage until the late 1990s, when it was refurbished for participation in the U. S. Navy's VECTOR program. The book ends with a comprehensive discussion of lessons learned and includes an Appendix containing detailed information.
