一种非对称双翼结构弹丸减速导旋特性试验研究

Experimental Study on Decelerating and Spinning Characteristics of an Asymmetric Two-wing Projectile

非对称双翼结构弹丸利用两个大小不同的刚性翼片提供非对称的气动力和气动力矩使弹丸形成所需的稳态扫描运动。为了分析非对称双翼结构弹丸的减速导旋特性,文中设计了一种非对称双翼结构弹丸的高塔投放试验方法,通过改变翼片形状、翼片面积及翼片布局,分析了不同非对称双翼结构对弹丸实现减速导旋性能的影响。

The asymmetric two-wing projectile is made up of a columned body and two different rigid wings. With the help of asymmetric aerodynamic forces and aerodynamic moments offered by the two wings, the stable scanning motion can be finally carried out. In order to analyze the decelerating and spinning characteristics of the asymmetric two-wing projectile, a tower throwing test method was designed. By changing the shape, area and layout position of the two wings, the different influence on the decelerating and spinning characteristics of the projectile were analyzed.
