The calculations are conducted using a prediction system of rotor noise jointly developed by ATIC and NAL. As a result of the comparison, the prediction method reasonably predicts the aerodynamic and acoustic characteristics of the model rotor. For the improvement of the accuracy of BVI (Blade Vortex Interaction) noise prediction, further investigation about the wake geometry will be needed. In the ATIC research program, the second model rotor test will be conducted at DNW in the beginning of 2000. The future work is to improve the present system by comparing the calculated results with the second DNW test data.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
