Numerical simulation and experiments of ground-based laser irradiating small scale space debris

This article investigated the effects of ground-based laser irradiating small scale space debris by numerical simulation and experiments. A dynamic model of ground-based laser irradiating small scale space debris was established, and the waveforms and arriving position of shock wave propagation with different laser pulses width were analyzed, the interaction relationship of jet velocity with different laser energies was discussed, and the distributed rules of impulse coupling coefficient with different laser pulses width and power densities were also described. As a result, the removing effect of the small scale debris was described to evaluate the cleaning influence. This paper provides analyses for establishing removing schemes of small scale debris and selecting suitable parameters ground-based laser system.
