JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EDA201J07 Subject Category: Aeronautical Technology PDF Responsible Representative: Kazuyuki Nakakita, Aeronarutical Technology Directorate, Fundamental research unit Contact Information: Yoimi Kojima(kojima.yoimi@jaxa.jp) Members: David Lusher, Sansica Andrea, Masashi Kanamori, Kenji Hayashi, Yoimi Kojima Abstract Under off-design flight conditions, where an aircraft deviates from its steady operational state, the aircraft geometry becomes more complex and unsteady phenomena tend to arise, leading to a significant increase in the computational scale of fluid simulations. In・・・<<read more>>
JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EDA201J08 Subject Category: Aeronautical Technology PDF Responsible Representative: Kazuyuki Nakakita, Aviation Technology Directorate, Fundamental Aeronautics Research Unit Contact Information: Shingo Matsuyama(matsuyama.shingo@jaxa.jp) Members: Shingo Matsuyama Abstract In recent years, research and development on reusable rockets has been proceeding vigorously, and it is expected that many new technologies not used in conventional expendable rockets—such as rocket retropropulsion and grid fins—will be adopted. In establishing these core technologies, there is a strong expectation・・・<<read more>>
