摘要
阻力大是栅格翼的主要缺点。文中通过数值计算,对带有不同前后掠角度的栅格翼与普通栅格翼的气动特性进行了分析研究。数据结果表明:带有前后掠角度的栅格翼的减阻特性显著,同时拥有较好的升阻比特性,且亚音速下,前掠式栅格翼要比后掠式栅格翼的气动特性更好。
Resistance is the main drawback of grid fins. Though numerical calculation, the research of aerodynamic characteristics of grid fins with different forward-swept and back-swept angle and normal grid fins. The data shows that the grid fins with forward-swept and back- swept angles have better drag reduction characteristics and lift-drag ratio characteristics, what＇ s more, the forward-swept grid fins have much better aerodynamic characteristics than the back-swept one under subsonic condition.
