Numerical Calculation Technique for Non-stationary Hypersonic Flow Around Vibrating Axisymmetric Body of Rotation Under Condition of Intensive Surface Mass Exchange

Results of non-stationary aerodynamic characteristics studies are presented for hypersonic flow around bodies having complex geometric forms under condition of intensive surface mass exchange. A goal of the studies is to determine rotary derivatives with application of the method of free vibrations. The studies have allowed finding peculiarities of the non-stationary flow around the bodies at various Reynolds numbers (Re_∞) and angles of attack. It is found that the surface mass exchange leads to the transition of a boundary layer into the turbulent one and a significant change of the external flow pattern.
