| Abstract | Efficient Global Optimization methods combined with high fidelity CFD analysis have been developed at ONERA and JAXA, respectively. Considering the technical requirements aroused from design of next generation high speed rotorcraft, it is beneficial to both parties to carry out a cooperative research on the optimization of helicopter rotor blades to share experience for best practice in this field. This co-operative research consists of two phases. As Phase 1, the aerodynamic optimization of rotor twist at a given thrust in hovering was discussed. As a result, the Kriging model based methods of both parties gave similar results. In this paper, multi-point optimization for hovering and forward flight is analysed as Phase 2. The obtained multi-point optimization results show reasonable twist distribution, which is intermediate between single objective optimization results of hovering and forward flight. In all of cases, a BO-105 40% scaled rotor is used as a baseline. |
