Abstract : The problem of minimizing the zero-lift drag of two-dimensional wings in supersonic flow is con sidered including the effect of friction. It is assumed that the distribution of pressure coeffi cients is that which results from the linearized theory, that the friction coefficient is con stant, that the chord of the airfoil is free, and tat any number of conditions is imposed on the thickness, the enclosed area, the moment of in ertia of the contour, and the moment of inertia of the enclosed area. By means of the indirect methods of the calculus of variations, a general solution is obtained. (Author)
