摘要

极小展弦比翼身组合体在大攻角飞行时会形成非对称涡,产生很大的侧向力。为减小侧向力,研究了前体小翼对极小展弦比翼身组合体气动特性的影响。采用有限体积法对极小展弦比翼身组合体流场进行了数值模拟。对比了有无前体小翼翼身组合体气动参数随攻角变化趋势以及空间流场结果,重点分析了前体小翼对侧向力的影响。结果表明,前体小翼的存在可以显著降低全弹的侧向力,并且对全弹的零阻和法向力影响很小。

Abstract

In order to reduce the lateral force by controlling the asymmetric vortexes, the effect of strakes on the forebody was investigated. The flow over very low aspect ration wing-body configuration with/without forebody strakes was simulated using finite volume method. The free Mach number was 0.8, and the Reynolds number was 2.36×105. The results indicate that the side force is reduced by forebody strakes; the drag force and the normal force are insensitive to the forebody strakes.

Key words： forebody strakes; high angle of attack; asymmetry vortex; very low aspect ratio
