In this test, the effects of higher harmonic control (HHC) and active flap control (AFC) on rotor blade-vortex interaction (BVI) noise were investigated. The frequency of the control was 20 Hz (2/rev), and the amplitudes of HHC and AFC were +/- 2.0 deg and +/- 15.0 deg, respectively. The phase of control was changed at intervals of 45 deg. Two types of BVI were tested: forced vortex interaction using the vortex generator upstream of a non-lifting rotor, and self-generated vortex interaction of a lifting rotor. As a result, the effects of BVI noise reduction were observed in the some cases.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0046103000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TM-771","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory (NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1347-460X","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00314334","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所 流体科学研究センター"},{"subitem_text_value":"航空宇宙技術研究所 流体科学研究センター"},{"subitem_text_value":"航空宇宙技術研究所 流体科学研究センター"},{"subitem_text_value":"航空宇宙技術研究所 流体科学研究センター"},{"subitem_text_value":"川田工業 航空・機械事業部"},{"subitem_text_value":"川田工業 航空・機械事業部"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Fluid Science Research Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Fluid Science Research Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Fluid Science Research Center"},{"subitem_text_language":"en","subitem_text_value":"National Aerospace Laboratory Fluid Science Research Center"},{"subitem_text_language":"en","subitem_text_value":"Kawada Industries Inc.
