Print on Demand. This book presents a numerical technique to design supercritical airfoils for increased efficiency in aircraft performance. Developed from computational transonic aerodynamics, the method outlined by the author solves the inverse problem of calculating the shape an airfoil must have in order to achieve a specified pressure distribution. The book includes descriptions of pressure distributions that generate airfoils with low wave drag, and indicates how to modify the input distribution in order to obtain airfoils with a desired lift, thickness to -chord ratio, and design Mach number. The author provides a convergence proof for the design problem in a special case of subsonic flow, and a description of the modified version of the Bauer, Garabedian, and Korn analysis code H, which is used to perform the flow calculations. Through the use of artificial viscosity, the author shows that it is possible to obtain wing sections with low wave drag by using the technique described in this book. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book.…

As the speed of the wing is increased, the supersonic zone grows in size and the pressure jump becomes larger. The occurrence of such shocks in the flow imposes a retarding force on the wing known as wave drag, which is one reason for the drag rise seen in Figure l. The large pressure gradients present in strong shocks can also induce separa tion of the boundary layer of air that adheres to the wing because of friction; separation results in a decrease in lift and more drag. The study of transonic flow is therefore important not only because transonic flow encompasses the most economical regime for aircraft opera tion, but because the deterioration of an aircraft's efficiency at higher speeds is due to transonic effects.
