改进CST方法在翼型优化设计中的应用
Application of Improved CST Parametric Method in Airfoil Design
摘要
Abstract
Class-shape transformation(CST)is a new airfoil parameterization method developed in recent years.Because of the good robustness and rare parameters involved,high precision,simple structure and so on,it is widely used in airfoil design and research.Based on the engineering practice of a small UAV,the application of CST method in the design of small UAV airfoil was discussed.And the influence of Bernstein polynomial order on the fitting accuracy of CST method was analyzed.The simulation results showed that the modified CST parametric method of Bernstein polynomial could satis?fy the geometric shape fitting precision of Clark Y airfoil well under the condition of BPO>4,and could be used to design and optimize the UAV's airfoil.关键词
