Abstract

The present work reviews Graham's (1952) use of orthogonal loadings as a method for obtaining minimum-drag wing shapes and shows how this method could be adopted for automatic calculations. It is shown that the orthogonalization process amounts to diagonalizing a certain matrix. The Lagrange multiplier method is then used to solve the problem of obtaining minimum drag subject to given lift and pitching constraints.
