JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24ECMP26 Subject Category: Competitive Funding PDF Responsible Representative: Kazuyuki Nakakita, Aviation Technology Directorate, Aircraft Lifecycle Innovation Hub Contact Information: Andrea Sansica(sansica.andrea@jaxa.jp) Members: Haruyuki Kakimoto, Keiichi Kitamura, Tomohiro Mamashita, Sora Yasui, David Lusher, Andrea Sansica Abstract In this study, we move from the MUSCL framework and use the MUSCL-THINC method, which gives the physical quantity distribution within a numerical cell as a hyperbolic function, allowing to sharply capture shock wave discontinuities.・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24ECMP27 Subject Category: Competitive Funding PDF Responsible Representative: Kanako Yasue, Aviation Technology Directorate, Aviation Integration Innovation Hub Contact Information: Shigeru Sunada(shigeru.sunada@mae.nagoya-u.ac.jp) Members: Mahiro Iwaki, Fumihiro Kajiwara, Ryo Nishino, Hideaki Sugawara Abstract In recent years, aircraft electrification has been advancing in the aviation industry. A flight of an airplane with batteries is strongly disturbed with a wind, because they are small and light. We focus on an electric airplane having multiple・・・<<read more>>
JAXA Supercomputer System Annual Report February 2024-January 2025 Report Number: R24ECMP28 Subject Category: Competitive Funding PDF Responsible Representative: Masashi Harada, Aeronautical Thechnology Directorate, Aviation Safety Innovation Hub Contact Information: Mizue Munekata, Kumamoto Univercity(munekata@gpo.kumamoto-u.ac.jp) Members: Mizue Munekata, Junnosuke Suganuma Abstract Currently, SLT is developing a tilt-wing VTOL aircraft. It is necessary to develop a propeller that can demonstrate high efficiency over a wide range of speeds from low to high to meet the requirements of this aircraft. The propeller is designed・・・<<read more>>
