Abstract:
This paper presents a method and results of an experimental study of the ignition characteristics of samples of high-energy materials by multimode laser radiation. An even distribution of the radiation flux density on the end surface of a cylindrical sample is obtained by its rotation around the axis of symmetry with a given angular velocity. 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 CO2 laser with and without rotation rotation of the sample are presented.
