Reasons and benefits of using JAXA Supercomputer System
The analysis of the aerodynamic interaction between the rotor and the wing using the helicopter aerodynamic analysis code rFlow3D is computationally intensive.
Achievements of the Year
The aerodynamic interaction between the rotor and the wing of a compound helicopter in hover is simulated (Fig.1) . The aerodynamic interaction between the rotor and the wing of a compound helicopter in high speed flight is simulated (Fig.2) .
