20 mm空炸杀伤榴弹电子引信定距精度分析

讨论的20mm杀伤榴弹是适于单兵武器使用的新弹种，它采用可编程电子引信，使榴弹在目标附近空炸。为了保证榴弹的杀伤效能，必须考虑引信的定距精度。该文建立了20mm杀伤榴弹的外弹道模型，在对该模型分析求解的基础上，给出了榴弹初速波动时所对应的外弹道性能参数，分析对比了计时定距与计转数定距2种方式的定距精度。结果表明，计转数方式优于计时方式。

Distance Precision Analysis of Electronic Fuze for 20 mm Antipersonnel Shrapnel

The 20 mm antipersonnel shrapnel is a new ammunition of soldier weapon. The shrapnel is blasted in the neighborhood of aim by programming electronic fuze . In order to ensure antipersonnel efficiency of the shrapnel, the distance precision of the fuze must be considered. The model of exterior trajectory for 20 mm shrapnel is established. With quantity analysis of the model, the parameters of exterior trajectory at different initial velocities are provided . The distance precisions of two means for memorizing time and memorizing rotation are compared. Results show that the memorizing rotation mean is better than the memorizing time one.
