在飞行器设计中用计算方法设计超临面翼型已完全取代了选用现成翼型的设计方法。为考察已设计出的NPU翼型是否满足飞行器设计要求我们对其进行了全面气动分析,发现这些翼型尚有不足之处,有必要进行改进设计。本文以其中一个翼型为例,讨论了曲率 The design of the supercavity airfoil in aircraft design has completely replaced the design method of the ready-made airfoil. In order to investigate whether the NPU airfoil has been designed to meet the aircraft design requirements, we conducted a comprehensive aerodynamic analysis and found that these airfoils still have some shortcomings and that it is necessary to improve the design. In this paper, one of the airfoils is taken as an example to discuss the curvature
