Recent advances in astronautics have highlighted recovery systems as critical components for improving launch efficiency and operational economics in reusable rocket programs. This paper proposes a parachute-based recovery system design for reusable suborbital rocket payload modules, emphasizing multi-mission capability through controlled descent and landing. Through trajectory analysis of suborbital flight profiles, the research develops a robust parachute deployment mechanism employing multi-sensor data fusion for precise initiation timing, effectively mitigating recovery failure risks across diverse operational scenarios. Furthermore, the aerodynamic design of the payload module is optimized for critical flight stages, such as maximum dynamic pressure and transonic points, to enhance static stability during atmospheric re-entry. This design maintains the proper attitude of the payload module, facilitating smooth parachute deployment and effective deceleration. Ultimately, numerical simulations demonstrate the feasibility and advantages of the proposed system for recovery missions. The results indicate that this technology not only enhances the safety and reliability of recovery operations but also offers significant potential for cost control and reusability. {\bf Keywords: }reusable rocket systems; parachute recovery system; payload module design; aerodynamic design optimization
