JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19ETET26 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Aoyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Masashi Kanamori(kanamori.masashi@jaxa.jp) Members: Masashi Kanamori, Takahiro Yoshikawa Abstract Low-speed buffet is an aerodynamic vibration phenomenon that occurs during low-speed and high-angle-of-attack conditions. In order to safely fly an aircraft, it is important to analyze low-speed, high-angle-of-attack flows where low-speed buffet can occur. Therefore, in this project, CFD analysis is performed・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19ETET25 Subject Category: Skills Acquisition System PDF Responsible Representative: AOYAMA Takashi, Director, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: KOMATSU Yusuke(ksw.koma2@asagi.waseda.jp) Members: KOMATSU Yusuke Abstract Japan Aerospace Exploration Agency (JAXA) has been promoting research and development to establish hypersonic aircrafts which can cruise at Mach 5. High-Mach Integrated Control Experiment (HIMICO), which is a flight experiment under hypersonic conditions using the S-520 sounding rocket, has been planned in・・・<<read more>>
JAXA Supercomputer System Annual Report April 2019-March 2020 Report Number: R19ETET12 Subject Category: Skills Acquisition System PDF Responsible Representative: Takashi Aoyama, Aeronautical Technology Directorate, Numerical Simulation Research Unit Contact Information: Aeronautical Technology Directorate, Numerical Simulation Research Unit(ohmichi.yuya@jaxa.jp) Members: Masato Harafuji Abstract It is suggested that fluid phenomena of specific frequency may affect the dynamic instability of atmospheric entry capsules. In this study, numerical fluid calculation was carried out for the blunt body shape, and the wake structure was investigated using・・・<<read more>>
