✦ Synopsis

This paper considers the problem of hypersonic flow past two-dimensional thin aerofoils with sharp leading edges and attached shock waves. The analysis relies on another recent formulation of the hypersonic small disturbance theory, HSDT. The equations are reduced to a complicated functional-differential equation for which an iterative numerical scheme is employed. In each iteration both the functional and differential parts of the functional-differential equation are eliminated, thus reducing it to an algebraic equation. The iterative scheme is found to be stable and rapidly convergent, and the results obtained for the surface pressure and shock wave compare well with other exact and approximate methods.
