DIAGRAM FOR OPTIMUM DESIGN OF A SYSTEM OF SHOCKS IN AXIALLY SYMMETRICAL SUPERSONIC DIFFUSERS WITH EXTERNAL COMPRESSION,

Abstract

The article proposes a diagram for designing axisymmetrical supersonic multi-shock diffusers which considerably decrease the pressure losses during the stagnation of supersonic air flows. Such a diagram can be used for selecting the optimum geometry of the inner body of a diffuser and for determining the flow parameters. The diagram was constructed for a system consisting of a number of oblique shocks followed by a normal shock. The diagram gives the M number behind a shock and the angles of the shock front and the flow deflection as a function of the M number in front of the shock. Thus, by decreasing after each shock the number of remaining oblique shocks, the overall flow parameters and the geometry of the inner body of a diffuser can be determined. (Author)
