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.

Download or read book The Calculation of Downwash Behind Supersonic Wings with an Application to Triangular Plan Forms written by Max A. Heaslet and published by . This book was released on 1948 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method is developed, consistent with the assumptions of small perturbation theory, which provides a means of determining for a known load distribution, the downwash behind a wing in supersonic flow. THe analysis is based upon the use of supersonic doublets which are distributed over the plan form and wake of the wing in a manner determined from the wing loading.

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.
