在高速风洞中对外挂／内埋武器分离过程中的气动力特性进行了试验研究，试验同时研究了改善内埋武器分离特性的被／主动流动控制方法———前缘立齿和前缘射流，试验马赫数为0．6、0．9和1．5。采用内式天平获取了不同试验状态下武器模型的气动力数据。试验表明：与外挂武器相比，内埋武器分离过程中的气动力特性较复杂，存在机／弹分离安全隐患；弹舱长深比 L／D 对内埋武器分离特性影响明显，随 L／D 增大，武器最大俯仰力矩系数明显增加；被／主动流动控制方法均能有效改善内埋武器分离特性。

An experiment was conducted in a high speed wind tunnel to investigate external/internal weapon separation characteristics.Passive and active control methods,namely leading edge saw and leading edge mass injection,are explored to improve internal weapon separation characteristics.Test Mach numbers are 0.6,0.9 and 1.5.Force balance was used to obtain aerodynamics of weapon modal.Test results indicate that internal weapon separation characteristics are more complicated than that of external weapon,and it ex-ists potential hazard when internal weapon separating from carrier aircraft.Aerodynamic characteristics of internal weapon are dramatically affected by weapon bay length-to-depth ratio L/D ,peak pitching moment increases markedly with the increase of L/D .Both of passive and active control methods carried out in this paper can improve separation characteristics of internal weapon effectively.
