在内埋武器舱前缘设计扰流板进行流动控制,可改善内埋导弹分离过程的偏航力矩特性,从而使弹头反向舱门,保证分离航向安全。为了研究该问题,通过理论分析在内埋武器舱前缘设计了不同高度的扰流板;通过部件测力风洞试验研究了不同高度扰流板对舱内流型、内埋导弹偏航力矩特性的影响,进而分析了扰流板对内埋导弹偏航分离特性的影响;通过轨迹捕获风洞试验验证了分离偏航姿态角特性分析的可靠性。研究结果表明:在内埋武器舱前缘设计一定高度的扰流板可以有效控制舱内流型,改善内埋导弹分离的航向气动特性,提高分离航向安全性。
The design of the spoiler at the front edge of the embedded weapon cabin for flow control can improve the yaw moment characteristics of the embedded missile separation process, so that the warhead reverses the hatch to ensure the separation heading safety. In order to study this problem, the spoilers with different heights were designed by theoretical analysis. The wind tunnel with different height was used to study the effect of spoiler on the flow pattern, the yaw moment of embedded missile The influence of the spoiler on the yaw separation characteristics of the embedded missile is analyzed. The reliability of the analysis of the characteristics of the yaw attitude of the split yaw is verified by the wind tunnel test with trace capture. The results show that the design of a certain height of the spoiler at the leading edge of the embedded weapon cabin can effectively control the flow pattern in the cabin, improve the heading aerodynamic characteristics of the separated missile, and improve the separation heading safety.
