炮射子母弹子弹阻力系数研究

炮射子母弹子弹气动外形复杂,传统方法无法获取其弹道参数.根据炮射子母弹子弹特点,将子弹飞行过程分为过渡段和稳定段两个阶段,采用子弹模拟发射器进行小射角和大射角飞行试验,采集过渡段数据,求取子弹飞行阻力系数,为子母弹子弹落点散布以及毁伤效能评估奠定基础.

Research on the Drag Coefficient of Submunition Launched by Artillery

As the complex shape of the submuntion lauched by the artillery, the parameter of ballistics can't be determined by the traditional ways. The flight course of the submuniton was divided into two stages according to the characteristics of the submunition lauched by the artillery, which were the transitional stage and the stable stage. Using the analog emitter of the submunition, the flight testing was engaged with different quadrant angles. The drag coefficient was acquired by the testing data. And it lays a solid foundation for the simulation of the submunition dispersion and the evaluation of the damage efficiency.
