Study on Trajectory Model of Optimum Energy in the Propelled Phase by Rocket Mode of Laser Propulsion
Fan Zhong-ze, Cheng Fang and Zhang Ming-liang

In order to send the maximum payload to the target orbit using the minimum fuel consumption, the problem of the optimum trajectory in adopting a new concept of laser propulsion to launch the Nano-SAT was studied. The PONTI-LIYATE maximum principle is introduced to analyse the trajectory of the propelled flight phase based on a rocket mode of laser propulsion along the direction of the thrust. The problem of trajectory optimisation was resolved using a mathematic function with a variable flying time and the two point boundary value (TPBV). The method to the problem is verified.

Keywords: Laser propulsion, trajectory optimisation, maximum principle.
