Abstract
Flow details accompanying the interaction of a combined energy release and an aerodynamic body in supersonic flow are considered numerically on the base of the Euler equations. Comparison with non-combined energy deposition is analyzed. Intensification of the drag force reduction via introducing the internal part to the energy release is pointed out. Complicated unsteady vortex contact structures caused by the RichtmyerMeshkov instabilities are shown to be the reason of the reduction in drag. Suppression of shear layer instability and large scaled flow pulsations as the result of the combined energy release effect is established. The problems are considered for plane and cylindrical flow symmetry for blunt and pointed bodies and a wide class of combined energy source characteristics. Freestream Mach numbers are equal to 1.89 and 3.
