Abstract

The total impulse of the disc type laser ablation thruster is linearly related to the number of ablation points on the target plate and improving the utilization rate of the target plate is beneficial to obtain more ablation points on the limited target plate surface. In this paper, the structure of the laser ablation micro-thruster was designed, two ablation paths for thruster were put forward and analyzed, namely the circle path and the spiral path. The distribution of the ablation point on the target plate was theoretically modeled. Through calculation, the influence law on the utilization rate of the target plate by the size of the target plate and the size of the ablation point under the two paths is analyzed and compared. The results show that, the target utilization theory of circle path and spiral path can reach up to 78.54%; The research in this paper provides theoretical guidance and design reference for the utilization of the target plate of the disc laser ablation thruster.
