Two And Three Dimensional Unsteady Lift Problems In High Speed Flight PDF Download

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.
