Abstract
The need for increased efficiency in the use of our energy resources has stimulated applied research in many areas. Recently progress has been made in the field of aerodynamics, where the development of the supercritical wing promises significant savings in the fuel consumption of aircraft operating near the speed of sound. Computational transonic aerodynamics has proved to be a useful tool in the design and evaluation of these wings. A numerical technique for the design of two-dimensional supercritical wing sections with low wave drag is presented. The method is actually a design mode of the analysis code H developed by Bauer, Garabedian, and Korn. This analysis code gives excellent agreement with experimental results and is used widely by the aircraft industry. The addition of a conceptually simple design version should make this code even more useful to the engineering public.
