Use of the Supercomputer
Aerodynamic data and load analysis resuls are necessary to confirm the feasibility in the H3 launch vehicle critical design phase. Therefore, we obtain aerodynamic characteristic data by CFD using JSS2.
In the past, aerodynamical development was dependet on databases, but due to technological innovation, highly reliable caluculation using CFD became possible. Consequently, computational approch is applied in this project.
Necessity of the Supercomputer
Shorter analysis cost makes greater feedback to whole system study. In addition, more complex problem such as coupled vibration of launch vehicle and facility will be solve by using JSS2.
Achievements of the Year
