一种吸气式RP激光发射器已被提议作为传统化学发射系统的替代品。本文分析了RP激光器驱动的单级入轨系统的可行性。计算了从地面到地球同步轨道的轨道，并估算了包括激光基础开发在内的发射成本。通过CFD计算和循环分析评估发动机性能。结果表明，每单位初始飞行器质量2.3MW的光束功率是到达地球同步转移轨道的最佳值，需要3,000次发射才能弥补激光发射机的成本。
An air‐breathing RP Laser Launcher has been proposed as the alternative to conventional chemical launch systems. This paper analytically examines the feasibility of SSTO system powered by RP lasers. The trajectory from the ground to the geosynchronous orbit is computed and the launch cost including laser‐base development is estimated. The engine performance is evaluated by CFD computations and a cycle analysis. The results show that the beam power of 2.3MW per unit initial vehicle mass is optimum to reach a geo‐synchronous transfer orbit, and 3,000 launches are necessary to redeem the cost for laser transmitter.
