介绍了光子推进的基本概念及国外发展的动态。利用狭义相对论推导了物体运动情形下的光压公式和光子推进下物体的运动方程,分析了光子推进过程中的能量转换关系。针对两种不同的光子推进方案——利用强激光照射发射卫星和太阳帆进行了可行性分析。结果表明,用强激光照射产生的光压发射卫星成本太高,不是一种合适的推进方案,而“太阳帆”尽管受到的光压很小,但是经过长时间的缓慢加速,其飞行速度和距离还是相当可观的。
Introduced the basic concept of photon propulsion and the development of foreign countries. Using the special theory of relativity, the light pressure formula and the equation of motion of objects under photon propulsion are deduced under the motion of objects, and the energy conversion relation during photon propulsion is analyzed. For two different photon propulsion programs - the feasibility of using strong laser radiation to launch satellites and solar sail. The results show that the cost of launching a satellite with high pressure laser light is too high to be a suitable propulsion solution and the “solar sail” is slow to accelerate despite prolonged light pressure Speed and distance are still considerable.
