摘要

前后掠的方式能够有效的减小阻力,为了进一步解决栅格翼阻力大的缺点,文中针对栅格翼的气动特点,将翼型结构与前后掠式栅格翼的结构相结合并与普通栅格翼进行比较分析。采用结构与非结构的网格画法,在0.6~2.0Ma下,通过数值计算结果表明:带有翼型结构的栅格翼相对于不带翼型结构的栅格翼能够更好的减小波阻,而翼型后掠式的结构综合性能较好。

Abstract

Utilization of forward-swept and back-swept way can effectively decrease resistance, in order to further solve the disadvantage of large resistance of grid fins, based on aerodynamic characteristics of grid fins, the ordinary grid fins are compared with the gird fins with airfoil profile structure and forward-swept and back-swept structure. By using structured and unstructured gird in modeling, under 0.6 2.0Ma, as the numerical calculation results show that the grid fins with airfoil profile structure have more drag reduction characteristics than the grid fins without airfoil profile structure, the structure with back-swept airfoil profile is better.

Key words： grid fins; airfoil profile; forward and back swept angle; drag reduction characteristics; numerical simulation
