摘　　要：采用3阶WENO方法计算了空空导弹在6 km高度,马赫数Ma=2下双喷流工作的情况。针对有攻角的对侧双喷流和零攻角下成直角的双喷流进行数值分析,得到主要结论:攻角造成了上下喷流的非对称,喷流在导弹迎风面的作用力小于其在背风面的作用力;在成直角的双喷流作用下,两喷流之间的干扰会增强喷流的作用,得到的单喷流等效放大因子增大很多。Double jet flow field for air-to-air missile at 6 km altitude and Mα = 2 was calculated by using third order Weight ENO method. Contralateral double jet with 10° attack angle and right-angle double jet with 0°attack angle were numerically simulated. The results show that attack angle cause up-down asymmetry of jets, and the effect of jet located at upwind is stronger than that located at leeward. For right-angle double jet, the interaction of two jets can enhance effect of jet control, and the equivalent amplification factor of single jet is greater than that of only one jet.
