Energy law of similitude for laser propulsion refers to the law that there is an optimumnozzle configuration for the largest value of impulse coupling coefficient at certain incident laser energy.
The power of the optimum full-size pulsed jet nozzle is 1.5 times that of the ordinary ones of the same size.
所得最优的全尺寸脉冲喷嘴的功率是同尺寸普通喷嘴的1.5倍。
