Abstract:Aimed at the complicated aerodynamic constraints and geometry constraints of the aircraft design engineering,the high-fidelity unstructured-grid RANS equation solver, the FFD geometry parameterization method, the spring dynamic mesh method, the RBF function surrogate model and the PSO optimizer are integrated to build an aerodynamic shape multi-point optimization and design tool. It is employed for the advanced low-speed laminar-flow airfoil shape design and the high subsonic supercritical wing shape design via the single-point and multi-point cases, with/without the aerodynamic and the geometry constraints. The results show that the tool works, and the constraints and the intelligence optimizer automatically and effectively guide the airfoil and wing shape to change with improved aerodynamic performances.
