Before the experiment, to actually build the experimental model, the ideal wing configuration had to be modified. To evaluate the change in the configuration, the computational simulation was carried out. The result indicated that by modifying the distance between the wings, the shock wave cancellation become closer to the ideal. The experiment was carried out using the model designed with the computational simulation and for the comparison, the monoplane was also launched. In the experiment, to observe the shock waves created from the models, the shadowgraph images were captured using the high speed camera. The captured images indicated that the supersonic biplane model created the shock waves as predicted by the computational simulation and close to ideal shock wave cancellation was observed. Secondly, the pressure waves were measured underneath the flight path. The measured pressure history indicated that the supersonic biplane model can mitigate the shock wave propagates to the ground to one third of that of the shock waves created from the monoplane model. The low boom characteristic of the supersonic biplane was proven with the free flight experiment using the ballistic range for the first time., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064672014, レポート番号: JAXA-SP-09-011}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {バリスティックレンジを用いた超音速複葉翼低ブーム特性の検証実験}, volume = {JAXA-SP-09-011}, year = {2010} }
