Influence Factor Analysis of the Recoverable Rocket Trajectory Planning Based on Multi-Pulse Path Planning Model

Based on the robotic path planning method, this paper conducted a research on the multi-pulse trajectory planning model of the recoverable rocket, and verified whether the model has enough feasibility and recovery precision to satisfy the engineering requirements. Firstly, by comparing the instantaneous pulse model and finite pulse width overload model, this paper analyzed the effectiveness, feasibility and precision of the model. Then this paper verified the validity of the multi-pulse trajectory planning model and analyzed the influences of dynamic constraints on the rocket trajectory quantitatively. Lastly, this paper analyzed the limit of the pulse number and the influence factors of the pulse number. The analysis results show the multi-pulse trajectory planning model of the recoverable rocket is correct, and the trajectory generated by this model is feasible in engineering practice.
