Abstract
In this project, a study was conducted to find the optimum blade shape for a 6-rotor helicopter for Mars exploration, The optimization method by Efficient Global Optimization and the airfoil definition method by Class Shape Transformation were employed. The two-dimensional calculation by FaSTAR was used for the evaluation during the optimization, and rFLow3D was used to evaluate the performance as a rotor blade. The aerodynamic performance of CLF5605 airfoil adopted by Ingenuity at NASA JPL was referenced and compared, and the airfoil named TMU21k3-1, which improved the aerodynamic performance was obtained.

Reasons and benefits of using JAXA Supercomputer System
In order to effectively employ the JAXA-provided tools, FaSTAR and rFlow3D, it was necessary to run on the JAXA supercomputer, which has many application examples and is well-tuned.
Achievements of the Year
The optimization method by Efficient Global Optimization and the airfoil definition method by Class Shape Transformation were employed. The two-dimensional calculation by FaSTAR was used for the evaluation during the optimization, and rFLow3D was used to evaluate the performance as a rotor blade. Referring to the aerodynamic performance of CLF5605 airfoil adopted by Ingenuity at NASA JPL, we were able to obtain an airfoil TMU21k3-1 which achived better hovering perfomance than that of CLF5605 (Figs. 1 and 2).
