摘要
采用NURBS技术构造叶片几何模型,将叶片气动性能参数与几何模型控制相关联,引入人工神经网络对NURBS的控制权因子进行调节,使叶片几何模型与气动性能更好地匹配。通过具体实例的应用验证,表明该优化设计方法为叶片优化设计提供了一条新途径,有一定的应用前景。
The non-uniform relational B-spline（NURBS） technique was adopted to construct a geometrical model of a blade, the control of. which was inter-related with the aero-dynamic parameters of the blade. Artificial neural network was introduced to regulate the factors of the NURBS control and to match the geometrical model with its aero-dynamic performance. An application instance shows that this optimization design provides a new approach for blade optimization.
