The CFD (Computational Fluid Dynamics) technique has been used to analyze the mechanism of the noise generated from a helicopter rotor, specifically for the impulsive noise. Euler code for high speed impulsive noise was used for the comparison with ONERA (Office National d'Etudes et de Recherches Aerospatiales) code. The CFD code for blade vortex interaction noise is validated by using experimental data that was conducted in DNW (German Dutch Wind Tunnels) wind tunnel by the Advanced Technology Institute of Commuter Helicopter (ATIC). The new computer code by moving overlapped grid method is now developing under the research cooperation between NAL and Kawasaki Heavy Industries in order to investigate flow characteristics around a helicopter.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
