Tower Hall Funabori), Tokyo, Japan, This paper describes a hybrid method of CFD and prescribed wake model developed at Japan Aerospace Exploration Agency (JAXA). The base CFD code herein assumed is a three-dimensional compressible solver, <rFlow3D>, which has intensively been developed for helicopter applications at JAXA. The rFlow3D is a highly versatile CFD code that can numerically simulate flows around helicopter in a wide range of flow conditions, considering trimming and blade elastic deformation. In this study, the hybrid method is improved by introducing multi-trailers. Computational precision of the hybrid method is verified by comparing the computational results with the experimental data of HART-II (Higher harmonic control Aeroacoustics Rotor Test). Airload coefficient and BVI noise distribution approach to the experiment. And it is also found that computational time reduces about half to one-third of CFD/CSD (computational structural dynamics) coupling if CFD is conducted after the hybrid method is utilized since the hybrid method reflects periodic induced velocity of the prescribed wake model and a faster convergence in elastic deformation can be obtained., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA0062268012, レポート番号: JAXA-SP-13-011},
