Introduction
The idea to use the energy deposition, localized in supersonic flow upstream of a body, for the improvement of aerodynamic characteristics was proposed in Russia more than 20 years ago. Theoretically the effects of wave drag reduction and flow reorganization were observed for supersonic flow past sphere by Georgievskiy and Levin [1]. Experimentally the wave drag reduction of blunt and streamlined bodies was confirmed when the optical laser spark was realized in upstream supersonic flow in single pulse mode by Yuriev et al. [2] and in pulse-periodic quasi-stationary mode by Tretiyakov et al. [3]. The recent survey of flow control and aerodynamic drag reduction by the energy deposition was presented by Knight [4].
