| Outline of Final Research Achievements |
This study aimed for vastly improving supersonic aerodynamic performance by repetitive laser pulse energy depositions. The following results were obtained: (1) Utilizing the momentum production from the interaction between a shock wave and a laser-heated bubble, a wave drag reduction of higher than 20 % and an efficiency of energy deposition of 10 (1000%) were obtained. (2) It was demonstrated that boundary layer separation could be suppressed by the laser energy deposition onto shock wave-boundary interaction region. (3) A standard deviation of one order in magnitude larger than the average decrement in post-shock overpressure modulation past turbulence was obtained, thereby demonstrating the possibility of strongly influencing pressure fields even through weak spatiotemporal inputs.
