This book was released on 1949 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conformal mapping methods are applied to the calculation of the effect of channel (two-dimensional tunnel) walls on the idea flow past arbitrary airfoils situated anywhere within the channel. The walls of the channel need not be plane but may have any shape. The results are compared in specific cases with those obtained by two approximate methods: the first of which is a first-order treatment using image vortices and doublets, and the second is a higher-order correction developed by Goldstein.

Download or read book The Conformal Transformation of an Airfoil Into a Straight Line and Its Application to the Inverse Problem of Airfoil Theory written by William Mutterperl and published by . This book was released on 1944 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Summary: A method of conformal transformation is developed that maps an airfoil into a straight line, the line being chosen as the extended chord line of the airfoil. The mapping is accomplished by operating directly with the airfoil ordinates. The absence of any preliminary transformation is found to shorten the work substantially over that of previous methods. Use is made of the superposition of solutions to obtain a rigorous counterpart of the approximate methods of thin-airfoil theory. The method is applied to the solution of the direct and inverse problems for arbitrary airfoils and pressure distributions. Numerical examples are given. Applications to more general types of regions, in particular to biplanes and to cascades of airfoils, are indicated.

This book was released on 1949 with total page 646 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic forces and moments exerted on pitched and yawed wing-body combinations consisting of a slender body of revolution and a cruciform arrangement of thin wings have been investigated by two theoretical methods. One method, an extension of the slender wing-body theory of NACA TN No. 1662, makes possible the determination of simple closed expressions for the load distribution, of simple closed expressions for the load distribution, the forces, and the moments for slender cruciform-wing and body combinations in which the wings may be dissimilar plan form. The second method treats cruciform-wing and body combinations consisting of a body of revolution and identical wings of arbitrary aspect ratio and plan form. The results are valid at subsonic, transonic, and supersonic speeds.

This book was released on 1946 with total page 630 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a first step toward the computation of the velocity distribution along a wing profile of arbitrary shape in a compressible fluid, the circulation-free flow around a symmetrical profile is treated under the assumption of the simplified density-speed relation due to Tchaplygin, Karman, and Tsien. The velocity distribution problem is reduced to a nonlinear integral equation which is solved by a fairly rapidly convergent iteration method. Numerical examples are given.

Download or read book The Theory of Subsonic Plane Flow written by L. C. Woods and published by Cambridge University Press. This book was released on 2011-06-09 with total page 619 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 1961 book presents a concise and systematic treatment of two-dimensional subsonic, inviscid fluid motion and its aeronautical applications. Part I surveys the relevant fluid dynamics, assuming only a basic knowledge of the topic. In Part II, the methods of conformal mapping and Cauchy integrals are developed, on the assumption that the reader has only an elementary understanding of complex variable theory; this will be of interest to a wide range of applied mathematicians and engineers. In Part III, the methods are applied to several problems in fluid mechanics and aero dynamics. The text provides an extensive account of mixed boundary-value problems and treats such examples of these problems as occur in ventilated wind-tunnel theory, jet-flap theory and unsteady Hemholtz motions.
