This book was released on 2013-06 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is a testament to the efforts of many people overcoming multiple technical challenges encountered while developing the XV-15 tilt rotor research aircraft. The Ames involvement with the tilt rotor aircraft began in 1957 with investigations of the performance and dynamic behavior of the Bell XV-3 tilt rotor aircraft. At that time, Ames Research Center was known as the Ames Aeronautical Laboratory of the National Advisory Committee for Aeronautics (NACA). As we approach the new millennium, and after more than 40 years of effort and the successful completion of our initial goals, it is appropriate to reflect on the technical accomplishments and consider the future applications of this unique aircraft class, the tilt rotor. The talented engineers, technicians, managers, and leaders at Ames have worked hard with their counterparts in the U.S. rotorcraft industry to overcome technology barriers and to make the military and civil tilt rotor aircraft safer, environmentally acceptable, and more efficient. The tilt rotor aircraft combines the advantages of vertical takeoff and landing capabilities, inherent to the helicopter, with the forward speed and range of a fixed wing turboprop airplane. Our studies have shown that this new vehicle type can provide the aviation transportation industry with the flexibility for highspeed, long-range flight, coupled with runway-independent operations, thus having a significant potential to relieve airport congestion. We see the tilt rotor aircraft as an element of the solution to this growing air transport problem.

Book excerpt: This monograph is a testament to the efforts of many people overcoming multiple technical challenges encountered while developing the XV-15 tilt rotor research aircraft. It is a comprehensive and detailed documentation of more than 40 years of effort at the NASA Ames Research Center designing this unique class of aircraft. The tilt rotor aircraft combines the advantages of vertical takeoff and landing capabilities, inherent to the helicopter, with the forward speed and range of a fixed wing turboprop airplane. NASA sees the tilt rotor as a new type of vehicle that will provide flexibility for high-speed, long-range flight, coupled with runway-independent operations. It takes the reader through the entire history, culminating with the first production of the V-22 Osprey, built for the U.S. Marine Corps, and the BA609 by Bell-Augusta. This publication takes the reader through the early ideas of Leonardo da Vinci through the search for an aircraft with Vertical Takeoff and Landing (VTOL) capabilities. There is abundant historical data about numerous innovative flying machines devised during the 1920s and 1930s, and German projects by Focke-Achgelis and Focke-Wulf. The publication includes illustrations from the 1930 flying machine patent of G. Lehberger, as well as the convertible aircraft patent of Haviland H. Platt (1955). The publication also describes how the XV-3 tilt rotor emerged from the Army/Air Force convertiplane program of the 1950s, and the evolution of tilt rotor, tilt wing, lift-fan, and direct lift versions and the evolution of the XV-3 program, which began in 1951. Flight tests are described in great detail, explaining the problems of stability. The development of tilt rotor aircraft technology involved some of the same factors that led to other important aeronautical accomplishments of this century. The vision of a few individuals in search of a practical and efficient new aircraft design, commitment to their goals, and their willingness to continue to pursue their objective while encountering major technical problems and programmatic challenges were critical ingredients in this tale. However, the unique aspect of the tilt rotor story was the combined Government and industry focused effort that was sustained for over four decades to explore, comprehend, develop, and refine this technology. The remarkable product of the investment of public and private funds, and the efforts of the people dedicated to the concept, is an aircraft type that will have an impact on civil and military aviation that will rival the introduction of the practical helicopter more than 60 years ago.

Available in PDF, EPUB and Kindle. Book excerpt: Few technological advances have affected the lives and dreams of individuals and the operations of companies and governments as much as the continuing development of flight. From space exploration to package transport, from military transport to passenger helicopter use, from passenger jumbo jets to tilt-rotor commuter planes, the future of flying is still rapidly developing. The essays in this volume survey the state of progress along several fronts of this constantly evolving frontier. Five eminent authorities assess prospects for the future of rotary-wing aircraft, large passenger aircraft, commercial aviation, manned spaceflight, and defense aerospace in the post-Cold War era.

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.

Available in PDF, EPUB and Kindle. Book excerpt: NOTE: NO FURTHER DISCOUNT FOR THIS PRINT PRODUCT- OVERSTOCK SALE-- Significantly reduced list price This new book from the NASA History Series tackles an interesting duo of biological problems that will be familiar to anybody who has seen photos of Apollo astronauts quarantined after their return to Earth.Namely, how do we avoid contaminating celestial bodies with Earthly germs when we send spacecraft to study these bodies, and how do we avoid spreading foreign biological matter from space when our robotic and human spacefarers return to Earth?Biological matter from an external system could potentially cause an unchecked epidemic either on Earth or in space so strict precautions are necessary. Each time a space vehicle visits another world it runs the risk of forever changing that extraterrestrial environment. We are surrounded on Earth by a melange of different microorganisms, and if some of these hitchhike onboard a space mission, they could contaminate and start colonies on a different planet. Such an occurrence would irrevocably alter the nature of that world, compromise all future scientific exploration of the body, and possibly damage any extant life on it.By inadvertently carrying exotic organisms back to Earth on our spacecraft, we also risk the release of biohazardous materials into our own ecosystem. Such concerns were recognized by scientists even before the 1957 launch of Sputnik. This book presents the history of planetary protection by tracing the responses to the above concerns on NASA s missions to the Moon, Mars, Venus, Jupiter, Saturn, and many smaller bodies of our solar system. The book relates the extensive efforts put forth by NASA to plan operations and prepare space vehicles that return exemplary science without contaminating the biospheres of other worlds or our own. To protect irreplaceable environments, NASA has committed to conducting space exploration in a manner that is protective of the bodies visited, as well as of our own planet."
Download or read book Mars Wars written by Thor Hogan and published by Government Printing Office. This book was released on 2009-08-13 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: On the 20th anniversary of the first human landing on the Moon, President George H.W. Bush stood atop the steps of the National Air and Space Museum in Washington, D.C. and proposed a long-range human exploration plan that included the successful construction of an orbital space station, a permanent return to the Moon, and a mission to Mars. This enterprise became known as the Space Exploration Initiative (SEI). The president charged the newly reestablished National Space Council with providing concrete alternatives for meeting these objectives. To provide overall focus for the new initiative, Bush later set a thirty-year goal for a crewed landing on Mars. Within a few short years after this Kennedyesque announcement, however, the initiative had faded into history the victim of a flawed policy process and a political war fought on several different fronts. The story of this failed initiative was a tale of organizational, cultural, and personal confrontation by key protagonists and critical battles. Some commentators have argued that SEI was doomed to fail, due primarily to the immense budgetary pressures facing the nation during the early 1990s. The central thesis of Mars Wars: The Rise and Fall of the Space Exploration Initiative suggests, however, that failure was not predetermined. Instead, it was the result of a deeply flawed decision-making process that failed to develop (or even consider) policy options that may have been politically acceptable given the existing political environment.

This book was released on 2005-12-31 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: These essays in celebration of the Wright brothers' first flight 100 years ago grew out of presentations by a group of prominent scholars in 2003 at a conference sponsored by the NASA History Division and held at the Great Lakes Science Center in Cleveland, Ohio. The volume focuses on the careers of some of the many men and women who helped to realize the dream of flight both through the atmosphere and beyond. These accounts are original and compelling because they examine the history of flight through the lens of biography.
