弹丸初速预测误差分析及模型改进研究

Research on Error Analysis and Model Improvement of Initial Velocity Prediction of Projectile

针对舰炮弹丸初速预测中由于冷膛修正量和使用上次射击弹丸历史初速数据对初速预测值造成的误差影响,分析误差产生原理,建立误差模型,提出预测改进模型。通过计算证明,该预测方法能够大大提高前4发弹丸的射击精度,解决部队使用测速雷达时由于预测弹丸初速误差影响舰炮射击精度的难题。

In view of the problem of error effects in due to the cold chamber correction projecttile velocity prediction and use historical data of velocity prediction, the cause of error about the initial velocity of shell is analyzed, error model is established and improved prediction model is putforward, proved by calulation, the prediction method can greatly improve the first 4 projectile firing accuracy and solve the problem about the difficult to predict the initial velocity of projectile accurately.
