Yonago Convention Center BiG SHiP), Yonago, Tottori Japan, This paper presents the results of numerical validation of experimental data about the aerodynamic interaction between a helicopter rotor and a fuselage model based on a newly established experimental database called JMRTS (JAXA Multi-purpose Rotor Test System) database. The CFD code used in the computation is called "rFlow3D ", which stands for rotor Flow 3D. rFlow3D has been developed by JAXA based on the three dimensional compressible Euler equations. The cell-centered Finite-Volume Method and the moving overlapping grids method are used in the computaion, where numerical flux is calculated by the mSLAU (modified SLAU) scheme, time accuracy is given by four-stages Runge-Kutta integration, and the implicit unsteady solver is constructed with a dual-time stepping method. Hover and forward flight cases are numerically simulated. In hover cases, the rotor performance was obtained in a good agreement with experimental data. In forward flight cases, the amplitude and the phase of fluctuations in pressure on the surface of blades and fuselage were also obtained in a good agreement with experimental data. These results indicate that the experimental data and numerical results mutually corroborate their authenticity., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0064967029, レポート番号: JAXA-SP-10-012}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {ロータ模型を用いた風洞実験データベースの構築と検証}, volume = {JAXA-SP-10-012}, year = {2011} }
