JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EDA201C17 Subject Category: Aeronautical Technology PDF Responsible Representative: Atsushi Kanda, Aviation Technology Directorate, Aviation Enviromental Sustanability Innovation Hub Contact Information: Seiji Yoshida, Aviation Technology Directorate, Aviation Environmental Sustainability Innovation Hub(yoshida.seiji@jaxa.jp) Members: YOSHIDA Seiji Abstract Lean‑premixed jet‑engine combustors are susceptible to combustion instability. Because the occurrence of combustion instability can damage the combustor and other engine components, the development of technologies to suppress its onset is essential. This study aims to・・・<<read more>>
JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EDA101C75 Subject Category: Aeronautical Technology PDF Responsible Representative: Kenichiro Nagai, Aeronautical Technology Directorate, Aviation Environmental Sustainability Innovation Hub Contact Information: Shunji ENOMOTO(enomoto.shunji@jaxa.jp) Members: Shunji Enomoto Abstract Ultra high bypass ratio aviation jet engines have a smaller sound absorbing liner area than conventional engines. In this project, we will develop sound-absorbing device technology that provides high noise reduction performance even with a small-sized sound-absorbing liner.
