Download or read book Drag Reduction by Shock and Boundary Layer Control written by Egon Stanewsky and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: The survival of the Aeronautical Industries of Europe in the highly competitive World Aviation Market is strongly dependent on such factors as time-to-market of a new or derivative aircraft and on its manufacturing costs but also on the achievement of a competitive technological advantage by which an increased market share can be gained. Recognizing this, cooperative research is continuously encouraged and co-financed by the European Union in order to strengthen the scientific and technological base of the Aeronautical Industries thus providing - among others - the technological edge needed for survival. Corresponding targets of research within Area 3, Technologies for Transport Means, and here in particular Area 3A, Aeronautics Technologies, of the Industrial and Materials Technologies Program ( Brite -EuRam III, 1994 -1998) have been identified to be aircraft efficiency, cost effectiveness and environmental impact. Concerning aircraft efficiency - relevant to the present research - a reduction in aircraft drag of 10%, a reduction in aircraft fuel consumption of 30%, and a reduction in airframe, engine and system weight of 20% are envisaged. Meeting these objectives has, of course, also a strong positive impact on the environment.

This book was released on 2013-04-17 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the description of an EC-sponsered program to study all relevant aspects of shock/ boundary-layer interaction control, the latter designed to improve aircraft performance at design (cruise) and off-design conditions. The work being presented includes a discussion of basic control experiments and the corresponding physical modeling, to account for shock control and a discussion of the airfoil experiments conducted for code validation and control assessment, in conjunction with the basic experiments and computations. The contents is comprised of a section giving a broad overview of the research carried out here and more detailed individual contributions by the participants in the research. Der Band enthält den Abschlußbericht eines von EU geförderten Projekts EUROSHOCK, das alle relevanten Aspekte der Kontrolle von Stoßfronten und Grenzschichten (wichtig z.B. für die Verbesserung der Flugeigenschaften von Fluzeugen) untersuchte. Neben einer ausführlichen Diskussion der grundlegenden Kontrollexperimente und der zugrundeliegenden Modellierung werden auch die Versuche an Tragflächen beschrieben, die zur Validierung von Modellrechnungen durchgeführt werden. Darüber hinaus enthält der Band auch die detaillierten Ergebnisse der Teilnehmer an dem Forschungsprogramm.

Book Synopsis Drag Reduction by Suction of the Boundary Layer Separated Behind Shock Wave Formation at High Mach Numbers by : B. Regenscheit
Download or read book Drag Reduction by Suction of the Boundary Layer Separated Behind Shock Wave Formation at High Mach Numbers written by B. Regenscheit and published by . This book was released on 1947 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an approach of the velocity of flight of a ship to the velocity of sound, there occurs a considerable increase of the drag. The reason for this must be found in the boundary layer separation caused by formation of shock waves. It will be endeavored to reduce the drag increase by suction of the boundary layer. Experimental results showed that drag increase may be considerably reduced by this method. It was, also, observed that, by suction, the position of shock waves can be altered to a considerable extent.

Book Synopsis Drag Reduction Due to Boundary-Layer Control by Combined Blowing and Suction by :
Download or read book Drag Reduction Due to Boundary-Layer Control by Combined Blowing and Suction written by and published by . This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A boundary system of combined blowing and suction is investigated. Blowing is applied in the front part of the body where the pressure gradient is favourable, whereas suction is applied in the rear part of the body where adverse pressure gradients exist. In order to avoid the 'sink drag' the volume rate of suction should be equal or smaller than the blowing volume rate. Theoretical investigations of laminar flows include optimization of the blowing velocity distribution as well as second-order boundary layer effects such as pressure drag and displacement effects on friction drag. Experimental results (mean velocities and shear stresses) of turbulent boundary layers with very strong blowing velocities near the stagnation point of a circular cylinder are used as a basis of a simple prediction method. Experiments on a circular cylinder show considerable drag reductions due to the combined blowing and suction boundary layer control systems.

Book Synopsis Shock Wave-Boundary-Layer Interactions by : Holger Babinsky
Download or read book Shock Wave-Boundary-Layer Interactions written by Holger Babinsky and published by Cambridge University Press. This book was released on 2011-09-12 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shock wave-boundary-layer interaction (SBLI) is a fundamental phenomenon in gas dynamics that is observed in many practical situations, ranging from transonic aircraft wings to hypersonic vehicles and engines. SBLIs have the potential to pose serious problems in a flowfield; hence they often prove to be a critical - or even design limiting - issue for many aerospace applications. This is the first book devoted solely to a comprehensive, state-of-the-art explanation of this phenomenon. It includes a description of the basic fluid mechanics of SBLIs plus contributions from leading international experts who share their insight into their physics and the impact they have in practical flow situations. This book is for practitioners and graduate students in aerodynamics who wish to familiarize themselves with all aspects of SBLI flows. It is a valuable resource for specialists because it compiles experimental, computational and theoretical knowledge in one place.
