摘要

摘要: 细长体在大攻角情况下会出现很大的侧向力. 在10°半顶角细长旋成体头部安置涡流发生器（微型三角翼），通过调节涡流发生器相对模型轴线的滚转安装角，实现了对大迎角状态下旋成体侧向力的近似比例控制.研究了涡流发生器半展长、后掠角和攻角等参数对侧向力控制效果的影响. 研究发现半展长为6mm、后掠角为45°的涡流发生器具有较好的控制效果，在一系列攻角下均能够实现侧向力的近似比例控制. 由于该机构非常简单，在工程中具有一定的应用前景.

Abstract: There is a large side force on the slender body at high angle of attack (AOA). Vortex generators (VG, a micro delta wing) are fixed on the tip of the slender body with 10° semi-apex angle as actuators in this paper. Side forces can change approximately proportional to roll setting angle of VG along the model axis at high AOA. Moreover, the effects of the parameters of VG, such as half-wingspan length, sweepback of lead edge and AOA have been researched. It is found that the vortex generators with 6mm half-wingspan and 45° sweepback show good performance on the presented slender body at a series of AOAs. This device is very simple that can be used in engineering in the future.
