摘要

摘要: 利用任意反射面激光干涉测速（VISAR）系统以及全光纤位移干涉仪（FDI），测量了线膛炮弹丸速度，获得了线膛炮弹丸在0~491 s内从零加速到140 m/s的速度历史，弹丸运动了20.7 mm，出炮口时的弹丸速度为817 m/s。实验结果表明，影响激光干涉测速技术在内弹道测量中应用的主要因素是炮口烟。研究结果对于深入探索激光干涉测速技术在内弹道测量中的应用有重要的参考意义。

Abstract: Using a laser velocity interferometer system for any reflector (VISAR) and a fiber displacement interferometer (FDI), the interior ballistic projectile velocity for rifle cannon was measured. According to the interference signal obtained directly from VISAR and FDI, whose persistence time is 491 s, the projectile velocity history ranging from 0 to 140 m/s was acquired. Therefore, the measurable displacement of projectile is 20.7 mm. In addition, the shot velocity at the muzzle was also obtained as 817 m/s. The experimental results showed that muzzle smoke is the dominant influencing factor. The research results will provide a valuable reference for the practical application of laser interferometer to interior ballistic measurement.
