基于记转数测速的定距修正系统

The Range Correction System Based on Turn-counting Velocity Measurement

为了增强武器系统的毁伤能力,提高对目标的命中概率,基于磁传感器记转数测速原理,提出了一种炮口初速修正弹丸起爆时间的定距系统.分析了记转数测速修正定距系统的基本原理,初步提出记转数定距系统方案.针对某小口径弹药,建立了弹道计算模型,并设计了定距系统的原理样机.静态实验和实弹回收试验证明了:记转数测速修正定距系统是可行的,能够较精确地实现定距起爆,提高相应弹药的毁伤效能.该设计思想和方法对装甲兵实现对地目标的高效毁伤具有一定的借鉴意义.

In order to improve the damage capability of the weapon system and the damage probability of the target, the range system which corrects the projectile initiation time with muzzle velocity by magnetic sensor based on velocimetry principle is proposed. The basic principle of the correction system based on turn-counting velocity measurement is analyzed, and the solution of distance system is given. For the small caliber ammuni- tion, a ballistic calculation model is established, and the range system is designed. The static experiments and recovery test show that： the correction range system based on turn-counting muzzle velocity measurement is feasible, and the damage efficiency of ammunition can be improved. This method provides a certain referential significance and a theoretical support for the armored force achieving high - effective damage to ground tar- gets.
