【摘要】 弹丸在膛内攻角的变化及其影响因素是发射动力学研究的重要内容，而测量弹丸攻角变化是实现此项研究的前提．最近研究成功的一种专门测量弹丸膛内运动姿态变化的实时测量系统，其构成及测量原理做了介绍，该系统在保证有足够量程的前提下，具有测角灵敏度的高精度和高采样频率，并实现了实时测量．最后提供了实弹射击试验和由此得出的弹丸膛内运动攻角变化曲线和炮管振动曲线．更多还原

【Abstract】 The changes of the yaw and its influence factor of projectiles are important contents for launch dynamics to research. In order to realizing the research the changes of the yaw of the poojectiles must measured. A real time measuring system of specially measuring the status changes of the projectile motion in bore has been researched suecessfully recently. Its construction and measuring theorem was described. Subject to having enough measuring range, the system possesses high measuring accuracy and sensitivity of angle and high sampling frequency. The real time measurement was realized. Finally gun firing test has been made. The change cruves of attack angle of projectiles in bore and the vibration curves of the barrels are provided.更多还原
