Reasons and benefits of using JAXA Supercomputer System
It is necessary to perform CFD computation including flow around a whole aircraft because it requires highly parallelized computation. Additionally, the JSS2 was chosen because the FaSTAR CFD solver is optimized, as well.
Achievements of the Year
To compare flight test results with ground test, such as wind tunnel testing and computational fluid dynamics (CFD), CFD analysis was performed. It includes Reynolds number effect confirmation and stabilizer deflection angle effect estimation in comparison between wind tunnel testing and flight test.
