In this concept the vehicle generates lift force by its body without wings. The lifting body shape has some advantages such as superior volumetric efficiency and better characteristics against aerodynamic heating at hypersonic speed. On the other hand, the disadvantages such as its low lift-drag ratio, poor stability and controllability at low speed make it more difficult to land on a conventional runway. LIFLEX (LIfting-body Flight Experiment), a flight experiment using a small and law-cost vehicle, has been planned to accumulate the knowledge and skills for automatic landing technology for liftingbody re-entry vehicle.This report describes about the flight path planning and the guidance low design for LIFLEX vehicle. A flight reference trajectory and feed-forward command profiles were designed by executing an six-degree-of-freedom open loop flight simulation. And, onboard compensation was added to modify the trajectory and feed-forward commands to handle various separation conditions and steady wind conditions. The structure of guidance law is based on the PID controller. The guidance feed-back gains were designed using MDM/MDP approach. These are the same architectures as that of ALELEX. Finally, six-degree-of-freedom simulations including a nominal case and six off-nominal cases were performed and all cases are satisfied all the required conditions during the flight and at the touchdown point.","subitem_description_type":"Other"}]},"item_3_description_18":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"形態: カラー図版あり","subitem_description_type":"Other"}]},"item_3_description_19":{"attribute_name":"内容記述（英）","attribute_value_mlt":[{"subitem_description":"Physical characteristics: Original contains color illustrations","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0064907000","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-RR-10-008","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":"1349-1113","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":"AA1192675X","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系システム技術研究開発センター"},{"subitem_text_value":"宇宙航空研究開発機構宇宙輸送系システム技術研究開発センター"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Space Transportation System Research and Development Center, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Space Transportation System Research and Development Center, Japan Aerospace Exploration Agency (JAXA)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"南, 吉紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"塚本, 太郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Minami, Yoshinori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsukamoto, Taro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-15"}],"displaytype":"detail","filename":"64907000.pdf","filesize":[{"value":"11.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"64907000.pdf","url":"https://jaxa.repo.nii.ac.jp/record/2063/files/64907000.pdf"},"version_id":"dbe5c8cd-d1a3-4b4b-9a65-c4f2d75d92b5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Re-Entry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Lifting Body","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Automatic Landing","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Space Plane","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Space Transportation System","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"リフティングボディ飛行実験(LIFLEX)誘導制御系: 基準軌道および誘導則の設計","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"リフティングボディ飛行実験(LIFLEX)誘導制御系: 基準軌道および誘導則の設計"}]},"item_type_id":"3","owner":"1","path":["112","1893"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"2063","relation_version_is_last":true,"title":["リフティングボディ飛行実験(LIFLEX)誘導制御系: 基準軌道および誘導則の設計"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T09:29:16.285366+00:00"}
