Experimental Research of Aerodynamic Hysteresis in Transonic Flow Around Blunt-Segmented Bodies with Flat Sides

On the basis of experimental research, conducted in a wide range of determining parameters (M^, Re, a) the main laws of changes in the stream structure of the transonic flow around blunt-segmented bodies of square and rectangular cross section are established, the changeover moments of separated and continuous flows are determined, the distinguishing features of the physical flow pattern and hysteresis areas in aerodynamic characteristics are revealed.
