JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EEE21100 Subject Category: Space Exploration PDF Responsible Representative: Kota Tanabe, JAXA Space Exploration Center, Space Exploration System Technology Unit Contact Information: Mitsuhisa Baba(baba.mitsuhisa@jaxa.jp) Members: Mitsuhisa Baba, Arnaud Delibie Abstract There is a risk that during spacecraft take-off and landing, large amounts of regolith will be scattered from the ground by the engine exhaust plume and that craters will be formed. We will develop technology to properly assess this risk and・・・<<read more>>
JAXA Supercomputer System Annual Report February 2025-January 2026 Report Number: R25EEG60100 Subject Category: Research and Development PDF Responsible Representative: Shuto Yatsuyanagi, Research and Development Directorate, Research Unit IV Contact Information: Shuto Yatsuyanagi(yatrsuyanagi.shuto@jaxa.jp) Members: Shuto Yatsuyanagi Abstract Hypersonic boundary-layer transition is a critical phenomenon in the design of atmospheric reentry vehicles and hypersonic cruise aircraft. At sufficiently high Reynolds numbers, the boundary layer undergoes transition from laminar to turbulent flow. Since the wall heat flux and skin friction in a turbulent・・・<<read more>>
