Author Description

This book reflects the author's experience in developing a computer program for the application of potential flow and boundary layer theories to the design and analysis of subsonic airfoils, including the evaluation of total lift, drag, and moment coefficients. The design part allows readers to compute the airfoil shape by means of a simple mathematical method from the properties of their velocity distribution, which can be specified in such a way that the boundary layer flow fulfills some given requirements. The most significant boundary layer phenomena such as laminar turbulent transition, laminar separation bubbles and boundary layer separation are considered. The first five chapters of this book describe in great detail a procedure for the design and analysis of subsonic airfoils. The data section contains 116 new airfoils for a wide range of Reynolds numbers and application requirements including general aviation aircraft, tailless airplanes, gliders, propellers, etc. The design features are explained and the input data for the computer code are given for all airfoils.
