摘要
激光推进是一种应用前景广阔的先进推进技术。讨论了激光推进发动机性能参数,飞行器在无大气阻力并忽略地球曲率和自转条件下发射与入轨所要求的最佳比冲,激光平均功率与电网能量消耗等问题。指出用激光发射微小卫星可以得到高质量比,激光推进发动机最优的比冲为12 240m/s。
Laser propulsion is an advanced technology with the prospect of wide apphcation. In this paper the main performance parameters of laser propulsion engine was analyzed. Such problems as the optimum specific impulse, the average laser power and the energy consumption of electric current for launching in 2D plane without air drag were addressed. The results show that higher mass ratio can be obtained by utilizing laser propulsion technology while the optimum specific impulse is 12240m/s.
