反坦克智能雷亚、跨音速气动特性数值仿真
Numerical simulation of subsonic and transonic flow flieds and aerodynamic characteristics of anti-tank intelligent mine
摘要
Abstract
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.关键词
