International Conference Center, Waseda University), Shinjuku-ku, Tokyo, Japan, In recent years, eVTOL (Electric Vertical Take Off and Landing Aircraft) such as electric multi-copter has been widely applied, and as a next step, it would be applied to logistics and passenger transportation called "Flying Taxi". In this paper, new PPB (Passive Pendulum Body) concept was proposed to achieve high cruising performance in a simple and lightweight manner for the transportation of the heavy payloads such as logistics and passengers over long distances. Performance estimation method based on the theoretical formula and the CFD analysis were summarized. Preliminary PPB conceptual study and the performance comparison with the conventional concept were carried out. Key expecting advantages such as the higher lift-to-drag ratio, the longer cruising distance, and the lower acoustic noise are identified. Finally, essential research needs are summarized for the establishment of PPB-type eVTOL vehicle., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1930011015, レポート番号: JAXA-SP-19-007},
