摘要
为了将激光干涉测速技术应用于火炮内弹道研究中,介绍了任意反射面激光干涉测速技术,针对37 mm直径滑膛火炮设计了长测量景深的光纤探头,选择了条纹常数为100 m/s的高灵敏度激光干涉测速仪,结合任意反射面激光干涉测速技术进行了2发火炮实验,实验测量的火炮弹丸最高速度为1 200 m/s,最长运动距离1.7 m,实验结果证明了该测试技术在火炮研究中的可行性和可靠性.
In order to apply laser Interferometry in the research of interior ballistic, the laser Velocity Interferometry System for Any Reflector (VISAR) was introduced. A wide range fiber probe was designed for the 37 mm caliber slip artillery, and a high sensitivity interferometry with velocity per fringe 100 m/s was used. Two shots were carried out by using laser velocity interferometry. The experiment shows that the projectile goes as long as 1.7 m and reaches a velocity of 1 200 m/s. The result shows that the VISAR can been used in the interior ballistic research and works well.
