| Outline of Final Research Achievements |
Design and evaluation systems for supersonic vehicles are constructed in this research to develop a low-boom supersonic vehicle based on Supersonic Biplane Theory. The following experimental and numerical simulation techniques were developed: free flight experiment of three-dimensional projectiles, surface pressure distribution measurement using ultrafast response pressure-sensitive paint, a calibration technique of pressure waveforms by the multipole method, a force balance measurement system in a supersonic wind tunnel, sonic boom estimation with consideration of the real atmospheric conditions, and design optimization and exploration for unsteady phenomena.
