The analytical and experimental studies of the aircraft’s supersonic air intakes have been carried out. An integrated approach to gas-dynamic designing that eliminates scale effect problem a wind tunnel with small-sized testing area is proposed. accelerates development process reduces resource intensity due rational distribution tasks between numerical physical experiments. results unique tests...

The objective of this work is to assess the ability of large-eddy simulations employing an equilibrium wall model to reproduce the flow features present in strong interactions between an oblique shock wave and the turbulent boundary layers of an internal (duct) flow leading to mean flow separation. Such interactions (denoted STBLI) are pertinent, among other applications, to supersonic flight p...

Tests of a conical-spherical body in supersonic wind tunnel were carried out on free oscillation installation along the pitch angle at Mach number M = 1.75 and two moments inertia relative to axis rotation. For with large moment inertia, self-oscillations amplitude ca. 10 deg obtained. first time, phenomenon degeneration for smaller has been discovered. An attempt was made model using an ordina...

To visualize the flow in test section of an indraft supersonic wind tunnel University Glasgow as long possible, a background-oriented schlieren system was built up preliminarily. A MATLAB program based on random dot algorithm developed this study provides fully customizable tool to generate background patterns with different sizes and densities. Background produced by in-house then can be print...
