Study on Thermal Effect Model of Laser Irradiating Moving and Rotating Target

摘要

A heat conduction model is presented in this paper, with the background of ground-based laser irradiating flying target. Firstly, the encounter scene of laser irradiating target is assumed, and the parameters of laser and flying target are given. Secondly, the calculation models of irradiation radius, power density distribution and convection heat transfer per unit area are derived. Finally, the heat conduction model is established which based on the encounter scene and irradiating parameters. As shown in the example, the heat conduction model can minutely describe the temperature field of metal/explosive structure irradiated by laser.
