In this paper, a discussion is given of some of the aerodynamic difficulties involved in the design of wings for high-subsonic speeds, and of the theoretical methods available to calculate sub-critical pressure distributions. It appears that until now only one of these methods, being in fact a semi-emperical one, is developed far enough to be of some help in the design stage. The main features of the method are discussed by giving attention to the two-dimensional flow problem and by describing the so-called centre solution of an infinite swept wing. The applicability of the method is shown both for two and three-dimensional flows by giving comparisons between measured and calculated pressure distributions. Nevertheless the method can not be regarded as a final statement. The development of digital computers in principle has made available for practical application a variety of more general promising approaches to the theoretical solution of subsonic flows around wings. It seems desirable in the authors views to pay full attention to the exploration cf the new possibilities.
