Abstract:

IN Part I, it is shown that application of the Dorodnitsyn-Belotserkovskii DB method can be greatly expedited and simplified by introducing a linearization process and a simultaneous stretching of coordinates in the spirit of the PoincareLighthill-Kuo method. The approach eliminates cumbersome iteration previously required by the DB method and standardizes the determination of a successive approximations, and b effects of changes in free stream Mach number and body profile for a given approximation. Details of analysis and procedure are presented in connection with the first approximation of the DB method the extension to subsequent approximations and to axisymmetric problems is outlined. In Part II, a comparison between theory and experiment is instituted for a two-dimensional asymmetric configuration tested in air gamma equals 1.4 at Mach 8 predicted pressure distributions and shock shapes are in good agreement with measurements.
