反坦克智能雷是一种依托高精度探测器件的新型智能反坦克炸弹。智能雷实现高效捕获、毁伤目标时，应考虑风阻系数等因素其飞行特性的影响。本文基于智能雷的三维模型，分析了亚、跨音速智能雷流场以及气动力因数随迎角的增长规律。应用计算流体力学软件对智能雷外流场进行数值计算，得到智能雷压心位置的变化规律。结果显示阻力系数的值比较大，有利于智能雷维持稳定扫描状态。智能雷附近剧烈的流场变化可能导致其扫描运动失效。仿真结果能够作为智能雷扫描稳定性分析、总体性能优化和外形改良的参照。

Anti-tank intelligent mine is a kind of new intelligent anti-tank bomb relying on high precision detector.It can effec-tively capture and damage targets with wind resistance coefficient and other factors affecting its flight characteristics under con-sideration.This article is based on the three-dimensional model of intelligent mine.To analyze its subsonic and transonic flow fields and the change law of aerodynamic force factor with the growth of the angle of attack,computational fluid dynamics soft-ware is used for intelligent mine flow field numerical calculation and the change law of pressure center.The results show that the large drag coefficient is conducive to the stability of scanning.Drastic changes of the flow field near the intelligent mine will disable its scanning movement.The simulation results can provide a reference for scanning stability analysis,overall perform-ance optimization and appearance improvement.
