Research Abstract |
This study aimed in the establishment of 'push-pull hybrid propulsion,' in which a small fraction of propulsion power is supplied to reduce a wave drag over a body in supersonic flow. We obtained an efficiency of energy deposition of up to 10. The drag reduction mechanisms, in which vortex rings generated by shock wavelaser-heated gas interaction played an important role were clarified.
