Joint Reconstruction Method for Rocket Trajectory and Spacecraft Orbit under Propulsion Failure in Lunar Mission
摘要
Abstract
To address the joint reconstruction of rocket trajectory and spacecraft orbit under propulsion failure in lunar missions,the Earth-Moon relative motion was incorporated into the guidance reconstruction framework,and a sequential solution approach was proposed in this paper.By establishing an equivalent transformation of the Earth-Moon transfer motion,the coupling between the trajectory and orbital constraints was decoupled,thus reducing the original problem into two subproblems:a constrained search for feasible transfer orbit,and the reconstruction of the rocket trajectory to inject spacecraft into the target transfer orbit.First,the overlapped conic method was employed to develop a transfer orbit search strategy that satisfies the Earth-Moon transfer motion constraints.Then,taking the obtained transfer orbit as the target,the rocket trajectory reconstruction problem was solved via an adaptive collocation method,with equivalent departure matching conditions constructed to ensure the consistency of the transfer motion between the reconstructed trajectory and the transfer orbit around the insertion point.A case study involving a single-engine failure during the second phase of the third-stage ascent process was simulated.The results demonstrate that the proposed sequential approach achieves rapid convergence,maintains consistency between rocket-spacecraft motion and Earth-Moon transfer by adjusting the orbital plane,and mitigates the adverse effects of prolonged rocket flight on the lunar transfer mission.This method provides a new conceptual direction for rocket mission reconstruction in extraterrestrial exploration and provides valuable insights for future research.关键词
