【摘要】 文章介绍了不同后掠角三角翼在进行俯仰振荡时的动态压力特性,说明这种动态压力特性同三角翼的法向力的变化是密切相关的,试验研究揭示了流态、压力和气动力之间的密切关系。同时试验研究显示三角翼上翼面压力的动态变化曲线呈现出双峰形态;不同后掠角三角翼在动态试验过程中压力、法向力都具有相似特性。更多还原

【Abstract】 In this paper, the dynamic pressure characteristics of different swept delta wings at pitching oscillation are presented. The test was performed in wind tunnel of BUAA. The results show that the dynamic pressure characteristics are closely correlation with the change of delta wing’s normal force. The experiment investigation have opened out that fluid state, pressure and aerodynamic force have been very affinity. Moreover, the experiment investigation indicates that graph of dynamic pressure distribution of upper wing of delta wing are presented with two humps, and that pressure and normal force of different swept delta wings have analogical characteristics.更多还原
