This book was released on 2017-12-11 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Effect of Lateral Shift of Center of Gravity on Rudder Deflection Required for Trim Two flights were made in a Brewster xsba-l airplane equipped with modified tail surfaces (fig. This airplane was known to have marginal rudder control for trim in some flight conditions and was therefore chosen as representative of the type involved in the problem of providing adequate rudder control in power-oh flight at low speeds. The center of gravity was shifted h.16 inches to the right for the first flight and h.16 inches to the left for the second flight. This shift was accomplished by asymmetric loading of fuel in the wing tanks. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 1944 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: Tests of a single-engine scout-bomber airplane showed that the rudder deflection required for trim at low speed in the critical wave-off condition may be reduced approximately 10° by a lateral shift of the center of gravity equal to 1.8 percent of the wing span. The reduction in rudder deflection required for trim consists of the rudder deflection required to offset yawing moments from the ailerons and from the component of the weight in the direction of the longitudinal axis and the rudder deflection required to hold the sideslip angle necessary to maintain straight flight. The effect of the lateral loading must be taken into account in tests to determine the adequacy of the rudder for trim. The lateral center-of-gravity location is also important in the service operation of airplanes because, by suitable distribution of the useful load in the wings, the ability of the rudder to trim the airplane in critical power-on conditions may be markedly improved.

Download or read book Flying beyond the stall written by Douglas A. Joyce and published by . This book was released on 2014 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "Much has been written about the famous conflicts and battlegrounds of the East during the American Revolution. Perhaps less familiar, but equally important and exciting, was the war on the western frontier, where Ohio Valley settlers fought for the land they had claimed -- and for their very lives. George Rogers Clark stepped forward to organize the local militias into a united front that would defend the western frontier from Indian attacks. Clark was one of the few people who saw the importance of the West in the war effort as a whole, and he persuaded Virginia's government to lend support to his efforts. As a result Clark was able to cross the Ohio, saving that part of the frontier from further raids. Lowell Harrison captures the excitement of this vital part of American history while giving a complete view of George Rogers Clark's significant achievements. Lowell H. Harrison, is a professor emeritus of history at Western Kentucky University and is the author or co-author of numerous books, including Lincoln of Kentucky, A New History of Kentucky, and Kentucky's Governors."

Book excerpt: Designed as a stopgap measure to provide overhead reconnaissance capability during the early years of the Cold War, the versatile U-2 has since evolved to meet changing requirements well into the 21st century. Though many authors have documented the airplane's operational history, few have made more than a cursory examination of its technical aspects or its role as a NASA research platform. This volume includes an overview of the origin and development of the Lockheed U-2 family of aircraft with early National Advisory Committee for Aeronautics (NACA) and National Aeronautics and Space Administration (NASA) involvement, construction and materials challenges faced by designers and builders, releasable performance characteristics and capabilities, use of U-2 and ER-2 airplanes as research platforms, and technical and programmatic lessons learned.
Download or read book Aeroplane Construction and Operation written by John B. Rathbun and published by DigiCat. This book was released on 2022-07-21 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many aeronautical books of a purely descriptive nature have been written for the average man, but as a rule they contain little interest for the more serious student of the subject. Other books of a highly technical and mathematical class have also been published, but their contents are all but unintelligible to anyone but a trained engineer. It is the purpose of the author to compromise between these two extremes, and give only that part of the theory and description that will be of practical use for the builder and flyer. The scope of the subjects covered in this volume has been suggested by the questions asked by students and clients and is the result of many years' correspondence with beginner aviators and amateur aeroplane builders. The author has endeavored to explain the principles of the aeroplane in simple, concise language, starting with the most elementary ideas of flight and finishing with the complete calculations for the surfaces, power, weight, etc. When mathematical operations are necessary they are simple in form, and are accompanied by practical problems worked out numerically, so that a man with even the most elementary mathematical knowledge will have no difficulty in applying the principle to his own work.
