Numerical simulation of three-dimensional temperature field of flying target irradiated by laser

Taking ground-based laser irradiating flying target as the background, the encounter scenes were established which included head on irradiating scene and transverse irradiating scene. Considering the varying of irradiating area and power destiny distributing, the laser irradiating parameters were solved, and the heat conduction model was established. The numerical simulation of three-dimensional temperature field of flying target was calculated by the finite volume method. The influence of target moving on temperature field was analyzed. Different from laser irradiating stationary target, the varying of irradiating parameters has a great influence on temperature field distribution. As the target moving, the values of irradiating area decrease gradually, and the values of average power density and the rate of temperature rising increase gradually. The spacial profile of laser beam and temperature rising area are different because of the difference of angle between laser beam and target.
