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.

This book was released on 2018-06-12 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document describes the design of the leading edge suction system for flight demonstration of hybrid laminar flow control on the Boeing 757 airplane. The exterior pressures on the wing surface and the required suction quantity and distribution were determined in previous work. A system consisting of porous skin, sub-surface spanwise passages ("flutes"), pressure regulating screens and valves, collection fittings, ducts and a turbocompressor was defined to provide the required suction flow. Provisions were also made for flexible control of suction distribution and quantity for HLFC research purposes. Analysis methods for determining pressure drops and flow for transpiration heating for thermal anti-icing are defined. The control scheme used to observe and modulate suction distribution in flight is described. Langley Research Center NAS1-18574; RTOP 522-32-31-01

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.

Book excerpt: ------------------------------------------------------------ This volume contains the Proceedings of the CEAS/DragNet European Drag Reduction Conference held on 19-21 June 2000 in Potsdam, Germany. This conference, succeeding the European Fora on Laminar Flow Technology 1992 and 1996, was initiated by the European Drag Reduction Network (DragNet) and organised by DGLR under the auspice of CEAS. The conference addressed the recent advances in all areas of drag reduction research, development, validation and demonstration including laminar flow technology, adaptive wing concepts, turbulent and induced drag reduction, separation control and supersonic flow aspects. This volume which comprises more than 40 conference papers is of particular interest to engineers, scientists and students working in the aeronautics industry, research establishments or academia.

Book excerpt: Innovation in aerospace design and engineering is essential to meet the many challenges facing this sector. Innovation in aeronautics explores both a range of innovative ideas and how the process of innovation itself can be effectively managed.After an introduction to innovation in aeronautics, part one reviews developments including biologically-inspired technologies, morphing aerodynamic concepts, jet engine design drivers, and developments underpinned by digital technologies. The environment and human factors in innovation are also explored as are trends in supersonic passenger air travel. Part two goes on to examine change and the processes and management involved in innovative technology development. Challenges faced in aeronautical production are the focus of part three, which reviews topics such as intellectual property and patents, risk mitigation and the use of lean engineering. Finally, part four examines key issues in what makes for successful innovation in this sector.With its distinguished editors and international team of expert contributors, Innovation in aeronautics is an essential guide for all those involved in the design and engineering of aerospace structures and systems. - Explores a range of innovative aerospace design ideas - Discusses how the process of innovation itself can be effectively managed - Reviews developments including biologically-inspired technologies, morphing aerodynamic concepts, jet engine design drivers and developments underpinned by digital technologies
