Introduction

Historically the potential of energy-assisted shaping of high-speed flows with modest on board power requirements has been the subject of a number of earlier investigations. The possibility of obtaining drag reduction using energy sources upstream of blunt bodies has been pioneered by Georgievskii and Levin [1] and Myrabo and Raizer [2] in theoretical studies. In their studies the magnitude of the drag reduction was found to be insensitive to the location of energy deposition at a sufficiently large distance from the body. This was followed up by various computational studies; Levin and Terenteva [3] and Riggins et al. [4] showed power savings over cones and blunt bodies using two dimensional Euler/laminar computations.
