地面火炮射程的外弹道优化设计

本文以射程为优化目标,对火炮弹丸在全弹道上从气动力、外弹道等诸性能方面进行了系统综合优化,同时,对火炮、弹丸外弹道优化理论中的一些问题进行了探讨,建立了优化设计数学模型,并采用数学规划方法求解,编制了相应的计算程序。利用该计算程序,只要根据下达的设计任务输入一些已知参数(如炮口能量、膛线缠度等),就可对弹丸最大射程的外弹道优化设计进行计算,给出最佳的弹重、初速、弹形参数等主要设计参数。文中还对175mm火炮弹丸进行了优化设计计算,并与原方案进行了比较.另外,利用该程序还可进行优化计算在满足一定射程时所需的最小炮口能量。

THE AEROBALLISTIC OPTIMIZATION ABOUT RANGE FOR ARTILLERY PROJECTILES

Taking the range as an objective function, the aeroballistic optimization has been made in the present paper from a point of view of aerodynamic and exterior ballistic performance for artillery projectiles. The model of optimum design, which can be solved by mathematical programming, has been set up and its computer program has been developed too. Based on the code, we can predict the longest range of a projectile and get some main parameters of design from some known data (such as the muzzle energy, twist, etc,), Comparison between the optimum parameters and the used parameters for a projec- tile of 175mm calibre artillery has been made. Additionly, from the code we can calculate the least muzzle energy at a certain range.
