Two types of rotor noise prediction code based on Kirchhoff equation and FW-H (Ffowcs Williams and Hawkings) have been developed. The CFD code is combined with rotor noise prediction code to predict the HSI (High Speed Impulsive) noise. For aeroacoustic validation, HSI wind tunnel test was conducted in NAL low speed wind tunnel. Sound pressure histories were obtained from 2.4 m diameter 2-bladed rotor. Results show the asymmetric sound pressure history that is typical characteristic of HSI noise and comparison between wind tunnel test results and numerical results show good agreement.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0032819030","subitem_description_type":"Other"}]},"item_5_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL SP-53","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_5_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0289-260X","subitem_source_identifier_type":"ISSN"}]},"item_5_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10097345","subitem_source_identifier_type":"NCID"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"三菱重工業"},{"subitem_text_value":"三菱重工業"},{"subitem_text_value":"三菱重工業"},{"subitem_text_value":"中菱エンジニアリング"},{"subitem_text_value":"航空宇宙技術研究所"},{"subitem_text_value":"航空宇宙技術研究所"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Mitsubishi Heavy Industries Ltd."},{"subitem_text_language":"en","subitem_text_value":"Mitsubishi Heavy Industries Ltd."},{"subitem_text_language":"en","subitem_text_value":"Mitsubishi Heavy Industries Ltd."},{"subitem_text_language":"en","subitem_text_value":"Churyo Engineering Co.
