Description

第53回流体力学講演会/第39回航空宇宙数値シミュレーション技術シンポジウム (2021年6月30日-7月2日. 日本航空宇宙学会 : 宇宙航空研究開発機構(JAXA)オンライン会議)

The 53rd Fluid Dynamics Conference / the 39th Aerospace Numerical Simulation Symposium (June 30 - July 2, 2021. The Japan Society for Aeronautical and Space Sciences : Japan Aerospace Exploration Agency (JAXA), Online meeting)

The axial force characteristics of the reusable vehicle ''RV-X'' was predicted using numerical flow analysis under the flight condition, in contrast with most of past related studies using only scale models. We focused on the return phase (150-180 degrees angle-of-attack), and validated our simulations by comparing the solutions against the wind tunnel test data. At 180 degrees, in particular, our results demonstrated that the absolute axial force value (i.e., drag working as aerodynamic brake) at the flight condition (Re = 9.0×10(exp 6) can be 87% smaller than that at the wind tunnel condition (Re = 6.6×10(exp 5)). Its mechanism was then explained in detail using the computational flow solutions at different Reynolds numbers.
