We propose and demonstrate feedback・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA21 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Hayato Kawashima (Yokohama National University)(kawashima-hayato-rn@ynu.jp) Members: Keiichi Kitamura, Hayato Kawashima Abstract In order to obtain the drag value of a slender body such as rockets from a wind tunnel test, the drag correction considering cavity pressure and base pressure is typically required to remove the effect of a sting. At first in・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA20 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Fumiya TSUTSUI (Yokohama National University)(tsutsui-fumiya-rt@ynu.jp) Members: Keiichi Kitamura, Fumiya Tsutsui, Yuya Yasumura Abstract Flying vehicles, such as rockets and supersonic parachutes, fly at supersonic speeds and play an important role in transporting goods. Hence, it is important to ensure stable flight. Factors that inhibit flight stability include protuberance on the rocket and・・・<<read more>>
JAXA Supercomputer System Annual Report April 2020-March 2021 Report Number: R20EACA18 Subject Category: JSS Inter-University Research PDF Responsible Representative: Seiichiro Morizawa, Lecturer, National Institute of Technology, Okinawa College Contact Information: Seiichiro Morizawa(morizawa@okinawa-ct.ac.jp) Members: Seiichiro Morizawa, Takashi Matsuno Abstract Birds such as hawks have excellent characteristics of flight efficiency and quiteness. One of these distingusished features is thought to be the shape of wingtip with multiple wings and gaps. The purpose of this project is to clarify these mechanisims of wingtip・・・<<read more>>
