The solution to compensating for the error of rifling angle was put forward. The data shows that the error of the rifling angle has a great influence on the accuracy of the velocity measurement. When the error is 9', it will cause about 1.75% of the velocity error, which will bring about the deviation of the accuracy. The compensation scheme of the rifling angle error based on the fuze setter was given. The experiment shows that the rifling error compensation scheme of the fuze setter can reduce the velocity error to about 0.2%, which can effectively reduce the fuze velocity error, improve the accuracy of air-burst fuze, and provide reference for the auto speed-testing fuze design. | 查看全文查看/发表评论下载PDF阅读器 | |
