摘要
为了分析引信外弹道受力情况,从而解决弹道炸问题,总结了不同稳定方式弹丸刚体外弹道学模型特点、气动力参数获取方式以及刚体外弹道学方程组解法,讨论解算结果的可信性,并对比分析准刚体外弹道学模型的特点和应用。准刚体外弹道学模型目前主要用于射表编制和炮兵火控系统,刚体外弹道学模型在求解精度与可信度方面优于准刚体外弹道学模型和质点外弹道学模型,能用于分析弹丸的章动规律、自转规律、风速对射程的影响规律等。
To solve the problem of ballistic burst,the characteristics of different stabilization methods of projectile rigid exterior ballistics models,the method of obtaining aerodynamic parameters and the solution of rigid exterior ballistic equations were summarized to help analyze the exterior ballistic force of fuze.Beside,the credibility of the calculation results were discussed,the characteristics of quasi-rigid exterior ballistic models was analyzed,and the advantages and applications of each ballistic model were concluded.The quasi-rigid exterior ballistic model was mainly used for the preparation of the firing tables and the artillery fire control systems currently.The rigid exterior ballistics model was superior to the particle exterior ballistic model in terms of accuracy and reliability,it could also be used to analyze the nutation and rotation law of the projectile and the influence of wind speed on the range.
