内埋武器机弹分离相容性研究进展综述

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.
