For the SRM, we clarify the generation mechanism of the pressure oscillation in the SRM. For the scramjet engine, we clarify the・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA43 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate professor, Yokohama National University Contact Information: Yoshikatsu Furusawa(furusawa-yoshikatsu-vz@ynu.jp) Members: Yoshikatsu Furusawa, Keiichi Kitamura Abstract As a new form of a Mars exploration vehicle, research and development of a Mars airplane are progressing. Since the Martian atmosphere is low density and the Mars airplane flies in the low Reynolds number region, the flow field around the Mars airplane differs・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA21 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama National University Contact Information: Hirokazu Kuirhara (Yokohama National University)(kurihara-hirokazu-nw@ynu.jp) Members: Hirokazu Kurihara, Keiichi Kitamura, Shogo Motoki Abstract In the case of the nose-entry system on vertical-takeoff-and-landing type reusable rockets, this rocket needs a turnover maneuver by using its pitching moment, during return flight. In this study, the effects of three types of slender body with different・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EACA20 Subject Category: JSS Inter-University Research PDF Responsible Representative: Keiichi Kitamura, Associate Professor, Yokohama Contact Information: Fumiya TSUTSUI (Yokohama National University)(tsutsui-fumiya-rt@ynu.jp) Members: Keiichi Kitamura, Fumiya Tsutsui, Yuya Yasumura Abstract Both launch vehicles and supersonic parachutes play an important role in space transportation, and fly at supersonic speeds. Factors that hinder safe flights include the generation of complex vortex structures caused by protuberances on the rocket’s surface and deformation of the・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EA3304 Subject Category: Aeronautical Technology PDF Responsible Representative: Yoshikazu Makino, Aeronautical Technology Directorate, Aviation Systems Research Unit Contact Information: Masahiko Sugiura(sugiura.masahiko@jaxa.jp) Members: Masahiko Sugiura, Keita Kimura, Hideaki Sugawara, Yasutada Tanabe, Kuniyuki Takekawa Abstract Compound helicopter is a one of the high-speed rotorcraft concepts. In high-speed compound helicopter, the rotor revolution is slower than the conventional helicopters, considering the effect of compressibility at the blade advancing side. In this case, a・・・<<read more>>
