極超音速飛行実験機(HYFLEX)の極超音速空力特性を航技研(NAL)のナビエ・ストークスCFD(計算空気力学)コードを用いた数値シミュレーションにより調べた。数値解析結果をNAL極超音速風洞で得られた実験データと比較した。実飛行時の空力特性を調べるため、空力加熱の最も厳しい飛行条件に対応する数値計算も行い、飛行条件と風洞試験条件の差を考察した。
Hypersonic aerodynamic characteristics of Hypersonic FLight EXperiment (HYFLEX vehicle were investigated by numerical simulations using Navier-Stokes CFD (Computational Fluid Dynamics) code of NAL. Numerical results were compared with experimental data obtained at Hypersonic Wind Tunnel at NAL. In order to investigate real flight aerodynamic characteristics. numerical calculations corresponding to the flight conditions suffering from maximum aero thermodynamic heating were also made and the differences between flight and experimental conditions were considered.
