Book Description
The indicial lift and pitching-moment coefficients are derived for flat-plate triangular wings at supersonic speeds. Coefficients are determined for angle-of-attack distributions corresponding to sinking and pitching wings. The wing with supersonic edges is completely analyzed, the wing with subsonic edges is partially analyzed; the solution in this case being completed for very narrow wings by an application of slender wing theory. In case of the supersonic edges, a comparison is made with known two-dimensional results and also with results for the same triangular wing in reversed flow.

Book Description
The problem of the build-u of lift on two- and three-dimensional wings flying at high speeds is discussed as a boundary-value problem for the classical wave equation. Kirchhoff's formula is applied so that the analysis is reduced, just as in the steady state, to an investigation of sources and doublets. Some simple applications of this method are considered, including the determination of the starting lift of a three-dimensional wing and the potential functions for some types of unsteady vortex motion.

Book Description
Calculations of the ratios of the velocity increments at test bodies to those at the tunnel walls caused by the solid blocking of these bodies within the walls of a closed rectangular wind tunnel are presented. The boides treated include two-dimensional airfoils; small bodies of revolution; straight, untapered, finite-span wings of varying span; and swept, untapered, finite-span wings of varying span. It is shown that, after wake blocking effects have been removed , the present method furnishes semiempirical blocking corrections for most wind-tunnel models and their components. The test section proportions of the Southern California Cooperative Wind Tunnel at CIT (ratio of height to width equal to 1/square root of 2) are used in the calculations.
