JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EDA201N15 Subject Category: Aeronautical Technology PDF Responsible Representative: Takashi Aoyama, Director, Aircraft Lifecycle Innovation Hub, Aviation Technology Directorate Contact Information: Atsushi Hashimoto(hashimoto.atsushi@jaxa.jp) Members: Atsushi Hashimoto, Kenji Hayashi, Kazuyuki Nakakita, Yoimi Kojima Abstract In aircraft certification, fight-test risk-reduction and cost-reduction are issues. CbA (Certification by Analysis), which replaces flight tests with analysis, is being studied globally in order to promote safe and efficient certification. Therefore, we are constructing a CFD-based flight・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EDA201N16 Subject Category: Aeronautical Technology PDF Responsible Representative: AOYAMA Takashi, Director, Aviation Technology Directrate, Aircraft Lifecycle Innovation Hub Contact Information: MIZOBUCHI Yasuhiro(mizobuchi.yasuhiro@jaxa.jp) Members: Hiroyuki Abe, Shingo Matsuyama, Yasuhiro Mizobuchi, Taisuke Nambu Abstract Fluid simulation in the aerospace field targets flow fields with turbulence and chemical reactions around aircraft and spacecraft. In addition, simulations of combustors for gas turbine engines and rocket engines sometimes have to deal with complex geometries. This・・・<<read more>>
JAXA Supercomputer System Annual Report February 2021-January 2022 Report Number: R21EDA101P00 Subject Category: Aeronautical Technology PDF Responsible Representative: Tatsuya Ishii, Director, Aeronautical Technology Directorate, Aviation Environmental Sustainability Innovation Hub Contact Information: Junichi Oki(oki.junichi@jaxa.jp) Members: Shunji Enomoto, Shono Noguchi, Junichi Oki, Daisuke Sasaki Abstract The trend in turbofan engines is towards higher bypass ratio and shorter nacelles. The eigne noise will increase due to smaller sound absorption area resulting from shorter nacelles. We aim to develop next-generation acoustic liner technologies that・・・<<read more>>
