内埋武器机弹分离相容性研究进展综述

为满足新型有人或无人作战飞机高隐身、高速和高机动性等要求，作战飞机普遍采用武器内埋挂载方式。当高速气流流过内埋武器舱的空腔时，将引发边界层分离、舱口附近会存在复杂的剪切流动、舱内会产生极为恶劣的噪声环境等非定常流动现象，这些复杂的非定常流动现象严重影响内埋武器机弹分离相容性（ASSC）。首先，给出内埋武器机弹分离相容性的重要研究意义；接着，重点介绍内埋武器机弹分离相容性的研究进展；最后，论述和总结了国内外采用4种方法（理论分析与建模、风洞试验、数值模拟和飞行试验）研究内埋武器机弹分离相容性及其流动控制方法的进展，指出内埋武器机弹分离相容研究存在的主要问题，并给出几点建议。

Review of aircraft-store separation compatibility of internal weapons

The internal weapon loading mode is widely used in new type manned or unmanned combat-aircraft to meet the requirements of high stealthy performance, high speed and high mobility. The high-speed airflow, when passing through the cavity of the internal weapon bay, will cause complex unsteady flow phenomena, such as boundary layer separation, complex shear flow near the hatch, and extremely acute noise environment in the cavity, seriously affecting the Aircraft-Store Separation Compatibility (ASSC). This paper mainly introduces the research progress of the separation compatibility for internal weapons after discussing the significance of the research. The progress of four methods (theoretical analysis and modeling, wind tunnel experiments, numerical simulation and flight tests) adopted both at home and abroad to study the separation compatibility and flow control methods for internal weapons is mainly summarized, the main problems in the study of separation compatibility for internal weapons are pointed out and suggestions are provided.
