Active impact on the flow around hypersonic flying vehicles

This paper deals with a numerical study of the influence of energy sources on the flow past hypersonic flying vehicles. One such example considered in this work is NASA HyperX X-43. Flight mode with $\mathrm{M}=6$ and angle of attack $\alpha=0^\circ$, $4^\circ$ was considered. Energy deposition was at various locations in front of HA. It is shown that energy input in front of the bow of the HA leads to a significant weakening of the bow shock wave and an increase in aerodynamic efficiency of the vehicle. The impact of energy input in the scramjet intake was also considered.
