This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on laminar flow and its transition to turbulent flow has been an important part of fluid dynamics research during the last sixty years. Since transition impacts, in some way, every aspect of aircraft performance, this emphasis is not only understandable but should continue well into the future. The delay of transition through the use of a favorable pressure gradient by proper body shaping (natural laminar flow) or the use of a small amount of suction (laminar flow control) was recognized even in the early 1930s and rapidly became the foundation of much of the laminar flow research in the U.S. and abroad. As one would expect, there have been many approaches, both theoretical and experimental, employed to achieve the substantial progress made to date. Boundary layer stability theories have been formu lated and calibrated by a good deal of wind tunnel and flight experiments. New laminar now airfoils and wings have been designed and many have been employed in aircraft designs. While the early research was, of necessity, concerned with the design of subsonic aircraft interest has steadily moved to higher speeds including those appropriate to planetary entry. Clearly, there have been substantial advances in our understanding of transition physics and in the development and application of transition prediction methodolo gies to the design of aircraft.

Download or read book A History of Suction Type Laminar Flow Control with Emphasis on Flight Research written by National Aeronautics and Space Administration and published by CreateSpace. This book was released on 2013-11 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar-flow control is an area of aeronautical research that has a long history at NASA's Langley Research Center, Dryden Flight Research Center, their predecessor organizations, and elsewhere. In this monograph, Albert L. Braslow, who spent much of his career at Langley working with this research, presents a history of that portion of laminar-flow technology known as active laminar-flow control, which employs suction of a small quantity of air through airplane surfaces. This important technique offers the potential for significant reduction in drag and, thereby, for large increases in range or reductions in fuel usage for aircraft. For transport aircraft, the reductions in fuel consumed as a result of laminar-flow control may equal 30 percent of present consumption. Given such potential, it is obvious that active laminar-flow control with suction is an important technology. In this study, the author covers the early history of the subject and brings the story all the way to the mid-1990s with an emphasis on flight research, much of which occurred at Dryden.

This book was released on 1951 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental measurements of the aerodynamic reactions on a symmetrical airfoil oscillating harmonically in a two-dimensional flow are presented and analyzed in this paper. Harmonic motions include pure pitch and pure translation, for several amplitudes and superimposed on an initial angle of attack, as well as combined pitch and translation. Considerable consistent data for pure pitch were obtained from a search of available reference material, and several definite Reynolds number effects are evident.

Book excerpt: In High-Speed Dreams, Erik M. Conway constructs an insightful history that focuses primarily on the political and commercial factors responsible for the rise and fall of American supersonic transport research programs. Conway charts commercial supersonic research efforts through the changing relationships between international and domestic politicians, military/NASA contractors, private investors, and environmentalists. He documents post-World War II efforts at the National Advisory Committee on Aeronautics and the Defense Department to generate supersonic flight technologies, the attempts to commercialize these technologies by Britain and the United States during the 1950s and 1960s, environmental campaigns against SST technology in the 1970s, and subsequent attempts to revitalize supersonic technology at the end of the century. High-Speed Dreams is a sophisticated study of politics, economics, nationalism, and the global pursuit of progress. Historians, along with participants in current aerospace research programs, will gain valuable perspective on the interaction of politics and technology.
