炮口初速测量校准与修正方法

弹丸炮口初速与实际炮口初速存在差异,此误差影响火炮的射击精度,因此有必要对弹丸的炮口初速进行测量校准并修正。对影响多功能炮口装置测速精度的因素进行了研究,得出自动机后坐速度对初速测量引入误差较大,据此提出一种炮口初速测量校准与修正系统方案来对多功能炮口测速装置进行测量校准与修正。最后,对实验数据进行分析,证明了该方法的正确性和可行性。

Research on Adjusting Measurement and Correcting Method for Muzzle Velocity

There are errors between the theory and practical value of projectile muzzle velocity.The error has a certain influence on fire accuracy of the gun.So it is necessary to measure and adjust the practical value of muzzle velocity.The paper analyzes the factor which influences the precision of the muti-muzzle velocity apparatus.Through analyzing,we found the main factor which reduces the measure precision is recoil of the gun.We put forward a system plan to measure and correct the projectile muzzle velocity.The muti-muzzle velocity apparatus is calibrated and corrected by the plan.Through experiment and analyzing the data,the plan is proved to correct and feasible,and also has the expect result and practical value.
