Outline

Space transportation that travels from Earth to space has been actively studied. On the other hand, atmospheric entry, the other space transportation from space to Earth, is still in the process of development. Spacecraft on the Earth orbit fly at a speed of over 7.8 km/s. When the spacecraft returns to the Earth, aero-deceleration by the atmosphere is necessary. It is important to understand the problems in this extreme environment, for example, aerodynamic heating due to high-temperature plasma, communication blackout, aerodynamic instability, and landing site dispersion. It is necessary to find insight into the development of spacecraft. I have focused on high-performance computers such as Fugaku. Now, I am engaged in a study to mitigate and solve the problems mentioned above by integrating space engineering and computational science approach.
