Book excerpt: June 28, 1972, the day I reported to the United Stated Military Academy at West Point, one of our class's first military acts was to subscribe to the Cadet Code of Conduct, swearing not to lie, cheat or steal ... nor tolerate among us anyone who does. I also pledged, as a cadet, and later as an officer, to preserve, protect, and defend the constitution of the United States. Any future allegiance I incurred fell subordinate to these two.Perhaps that's why I developed an affinity to the flying safety field which resides in a sacred niche within the sphere of flying. At the pinnacle of this citadel of truth resides the accident investigation process ... where there is no room or tolerance for politics or innuendo.I accepted the job to investigate the April 9th, 2010 CV-22 Osprey accident with reservations concerning the magnitude of the task and the inherent barriers preventing the collection of evidence a half-a-world away. But I failed to account for the obstacles of full disclosure, politics, and the reluctance of the same entities that assigned me the task, to accept the controversial findings of the investigation.If, at this point, you have read the first few pages of this book looking for an indictment of the government, Air Force, or the contractors who supply weapons of war, put the book back on the shelf ... or click remove from the digital cart. This is no vendetta, tell-all, hatchet job. This book is about facts and truth. Over a period of five months, the Air Force CV-22 accident investigation board traveled thousands of miles, interviewed over one hundred witnesses, and collected mounds of evidence in an inhospitable environment searching for the reason an Osprey aircraft impacted the ground in the remote desert of eastern Afghanistan. The accident took the lives of four personnel aboard the accident airplane.The following pages chronicle the unpublished and exhaustive investigation process, ending with my opinion of the cause of the Osprey accident on th

Download or read book Rotors Stress Analysis and Design written by Vincenzo Vullo and published by Springer Science & Business Media. This book was released on 2013-04-09 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stress and strain analysis of rotors subjected to surface and body loads, as well as to thermal loads deriving from temperature variation along the radius, constitutes a classic subject of machine design. Nevertheless attention is limited to rotor profiles for which governing equations are solvable in closed form. Furthermore very few actual engineering issues may relate to structures for which stress and strain analysis in the linear elastic field and, even more, under non-linear conditions (i.e. plastic or viscoelastic conditions) produces equations to be solved in closed form. Moreover, when a product is still in its design stage, an analytical formulation with closed-form solution is of course simpler and more versatile than numerical methods, and it allows to quickly define a general configuration, which may then be fine-tuned using such numerical methods. In this view, all subjects are based on analytical-methodological approach, and some new solutions in closed form are presented. The analytical formulation of problems is always carried out considering actual engineering applications. Moreover, in order to make the use of analytical models even more friendly at the product design stage, a function is introduced whereby it is possible to define a fourfold infinity of disk profiles, solid or annular, concave or convex, converging or diverging. Such subjects, even derived from scientific authors’ contributions, are always aimed at designing rotors at the concept stage, i.e. in what precedes detailed design. Among the many contributions, a special mention is due for the following: linear elastic analysis of conical disks and disks with variable profile along its radius according to a power of a linear function, also subjected to thermal load and with variable density; analysis of a variable-profile disk subjected to centrifugal load beyond the material's yield point, introducing the completely general law expressed by a an n-grade polynomial; linear elastic analysis of hyperbolic disk, subjected to thermal load along its radius; linear elastic analysis of a variable-thickness disk according to a power of a linear function, subjected to angular acceleration; etc.

Download or read book The Dream Machine written by Richard Whittle and published by Simon and Schuster. This book was released on 2010-04-27 with total page 622 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fascinating and authoritative narrative history of the V-22 Osprey, revealing the inside story of the most controversial piece of military hardware ever developed for the United States Marine Corps. When the Marines decided to buy a helicopter-airplane hybrid “tiltrotor” called the V-22 Osprey, they saw it as their dream machine. The tiltrotor was the aviation equivalent of finding the Northwest Passage: an aircraft able to take off, land, and hover with the agility of a helicopter yet fly as fast and as far as an airplane. Many predicted it would reshape civilian aviation. The Marines saw it as key to their very survival. By 2000, the Osprey was nine years late and billions over budget, bedeviled by technological hurdles, business rivalries, and an epic political battle over whether to build it at all. Opponents called it one of the worst boondoggles in Pentagon history. The Marines were eager to put it into service anyway. Then two crashes killed twenty-three Marines. They still refused to abandon the Osprey, even after the Corps’ own proud reputation was tarnished by a national scandal over accusations that a commander had ordered subordinates to lie about the aircraft’s problems. Based on in-depth research and hundreds of interviews, The Dream Machine recounts the Marines’ quarter-century struggle to get the Osprey into combat. Whittle takes the reader from the halls of the Pentagon and Congress to the war zone of Iraq, from the engineer’s drafting table to the cockpits of the civilian and Marine pilots who risked their lives flying the Osprey—and sometimes lost them. He reveals the methods, motives, and obsessions of those who designed, sold, bought, flew, and fought for the tiltrotor. These stories, including never before published eyewitness accounts of the crashes that made the Osprey notorious, not only chronicle an extraordinary chapter in Marine Corps history, but also provide a fascinating look at a machine that could still revolutionize air travel.

Download or read book The Story of Codebreaking written by Al Cimino and published by Arcturus Publishing. This book was released on 2017-11-30 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: To break a code, you have to put yourself in the mind of your enemy in order to probe the strengths and weaknesses of their systems. It's a game of bluff and doublebluff. The Story of Codebreaking describes undercover operations, power struggles, secret alliances, and brilliant feats of teamwork. Those who invent codes and those who break them are remarkable, indefatigable characters. Find out how Mary Queen of Scots smuggled cryptic messages to her accomplices when she was plotting against her cousin Elizabeth I, or discover the methods used by codebreakers during World Wars I and II, most significantly those who cracked Enigma and intercepted Japanese naval messages prior to Pearl Harbor. The sheer doggedness of those who unraveled the Enigma code is thought to have shortened World War II by almost two years. Topics include: • Ancient ciphers and the art of encoding • Early spies, subterfuge and skytales • The making and breaking of Enigma • Japanese naval codes in World War II • Cold War cryptography
