摘要

减阻是栅格翼研究中的一项重要任务。文中归纳了目前常用的减阻措施;通过对机翼后掠减阻的分析,以正置式栅格翼为基础,建立了格壁后掠的栅格翼的三维模型;然后进行数值模拟分析,结果表明格壁后掠对栅格翼气动特性和减阻特性起到了积极的作用,能够提高升阻比并减小阻力。

Abstract

Drag reduction is an important task in the study of grid fin. The previous measures of drag reduction were given in the paper. By analyzing the reduction in drag force of swept-wing, the 3D model of grid fin with swept-back angle based on positive type grid fin was given, and then the numerical simulation results showed that swept-back angle played a positive role in improving lift-drag ratio and reducing drag force.

Key words： grid fin; drag reduction; numerical simulation; fluid dynamic; swept-back angle; Fluent
