Study on Tail-fin Opening Characteristics of Image Terminal Guided Projectile Based on After-effect
摘要
Abstract
In order to study the tail-fin opening characteristics of the image terminal-guided-projectile,according to the structure characteristics and action principle of tail-fin,the movement process of the piston after starting and the rotation process of tail-fin were studied,which were coupled with the bore process and the after-effect process of the terminal guided projectile.The numerical simulation was carried out for the certain image terminal-guided-projectile.The pressure of projectile base and cylinder,displacement and velocity of projectile,displacement of piston,opening angle of fin and gas resistance were obtained.The results show that the relative errors of maximum pressure on the base,muzzle velocity,tail opening position and tail-fin opening angle are 3.2%,0.7%,4.7%and 5.7%respectively,which are within the allowable range.The related simulation curves are consistent with the actual change law,verifying the rationality of the model.On this basis,the influence of charge and pore diameter on tail-fin opening characteristics of image terminal-guided-projectile was analyzed from the perspective of equipment production and firing use,and the specific guidance was given.The research results can provide theoretical and data support for structure optimization design,strength check and abnormal mechanism research of the tail structure of the image terminal-guided-projectile,and also provide reference for development and use of other new-type cylinder-opening tail-fin projectiles.关键词
