摘要: 为了研究MJU-50B面源式红外诱饵弹圆柱形薄片在高速运动下发射的云团散布及运动过程,以薄片多体分离过程流场数值仿真为基础,建立了散布过程中薄片个体的刚体运动模型和220种工况下的气动力数据库,数值模拟了0.8马赫下诱饵弹上千片薄片的云团散布过程。仿真计算与试验数据对比分析表明:刚体运动模型能更好地模拟圆柱形薄片云团的散布过程,并提出新的薄片云团分布的特征形态;同时也验证了MJU-50B圆柱式薄片红外诱饵弹能在0.5 s内快速散开,散布面积大,分布均匀,并且能在3.0 s内保持其基本形态。

Abstract: A rigid body model and a database including 220 kinds of aerodynamic conditions are established to study the separation and dispersion of cylindrical plates of surface-type IR decoy launched at high-speed. The dispersion process of thousands of plates in surface-type IR decoy launched at 0.8 Mach is numerically simulated based on the flow field numerical simulation of plates’ multi-body separation process. Research results show that the rigid body motion model can be to use to simulate the dispersion process of cylindrical plates. The new distributing characteristics of plate cluster are presented. The surface-type infrared decoy filled with cylindrical plates is validated to quickly spread within 0.5s with a large dispersion area, and the hang time lasts more than 3.0 s with a uniform distribution.

Key words: ordnance science and technology, surface-type infrared decoy, dispersion of plate clusters, modeling and simulation
