Deployment Strategy for Solar Sails From a Resonant Periodic Orbit in the the Bicircular Restricted Four-Body Problem

This study investigates solar sail trajectory design within the bicircular restricted four-body problem (BCR4BP) framework by incorporating radiation pressure effects. A 4:1 synodic resonant orbit is constructed using numerical continuation techniques, followed by systematic stability analysis and parametric sensitivity evaluation. We propose a mission deployment strategy based on dynamical system theory, employing the maximum stretching direction criterion to establish a”green zone” for safe sail deployment. This optimized region ensures rapid orbital departure while preventing re-contact risks, significantly enhancing mission safety and operational reliability. The findings establish a theoretical foundation for solar sail trajectory design in multi-body gravitational environments and offer valuable insights for implementing solar sail technologies in future deep-space exploration missions.
