Abstract

This paper presents the method and results of an experimental study of the ignition characteristics of samples of high-energy materials by multimode laser radiation. A uniform distribution of the radiation flux density over the end surface of a cylindrical sample is obtained by its rotation around the axis of symmetry with a given angular velocity of rotation. The effect of convective heat transfer of the end surface of the sample with the environment on ignition characteristics is eliminated by placing the sample in a cylindrical container. The results of experiments on ignition of pyroxylin samples by a CO₂laser with and without rotation of the sample are presented.

激光辐射点燃高能材料的旋转样品

摘要

本文介绍了通过多模激光辐射对高能材料样品进行点火特性实验研究的方法和结果。辐射通量密度在圆柱形样品端面上的均匀分布是通过在给定的旋转角速度下绕对称轴旋转而获得的。通过将样品放在圆柱形容器中，消除了样品端面与环境的对流传热对着火特性的影响。给出了在有和没有样品旋转的情况下用CO ₂激光点燃吡咯啉素样品的实验结果。
