为了增大高亚音速飞行器的航程,一个有效的办法就是设计出气动效率高的气动外形。这必然要求产生升力L和阻力D的主要气动部件三元翼具有良好的气动性能。三元翼的气动特性与所使用的翼型气动特性有很大关系,而近年来出现的超临界翼具有较高的气动效率,因此为满足预研型号总体性能要求,我们进行了超临界翼研究。本文的目的是叙述超临界翼型的特点、设计及我们的研究结果。
In order to increase the high subsonic aircraft voyage, an effective way is to design aerodynamic and efficient aerodynamic shape. This necessarily requires that the main aerodynamic components that generate lift L and drag D have good aerodynamic performance. The aerodynamic characteristics of the ternary wing are closely related to the aerodynamic characteristics of the aerofoils used. However, the supercritical wing appeared in recent years has high aerodynamic efficiency. Therefore, in order to meet the overall performance requirements of the pre-research model, we conducted a supercritical wing the study. The purpose of this paper is to describe the characteristics of supercritical airfoils, design and results of our research.
