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 could be simulated in high speed flight (Fig.1) . The aerodynamic interaction between the rotor and the wing of a tandem compound helicopter could be simulated in hover (Fig.2) .
