To reduce the rotor-stator interaction, modified impeller and diffuser were designed by 3D inverse design method. The unsteady pressure fluctuations in the impeller and diffuser were evaluated by unsteady CFD (Computational Fluid Dynamics) technique. The results of CFD show the rotating pressure pattern, and also the mechanism of the interaction between the impeller outlet and the diffuser inlet. The modified stage consisted of the impeller with staking and the diffuser with inlet sweep have the effect to reduce the rotor-stator interaction caused by lengthening the blade passing time. The pressure fluctuations of modified impeller/diffuser system decreases 20-30 percent less than those of original impeller/diffuser system without the staking and the inlet sweep.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064093000","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: JAXA-RM-08-003","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Japan Aerospace Exploration Agency (JAXA)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1349-1121","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":"AA11983593","subitem_source_identifier_type":"NCID"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構 宇宙輸送ミッション本部　宇宙輸送系推進技術研究開発センター"},{"subitem_text_value":"荏原総合研究所"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Japan Aerospace Exploration Agency Space Transportation Propulsion Research and Development Center, Space Transportation Mission Directorate"},{"subitem_text_language":"en","subitem_text_value":"Ebara Research Co.
