The ramjet engine mounted on the experimental aircraft aims to start combustion by self-ignition of gaseous hydrogen fuel. However,・・・<<read more>>
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>>
