Design of intra-cabin laser wireless power transmission system for spacecraft

Laser wireless power transmission (LWPT) technology is an innovative approach for long-distance energy transfer via laser beams, demonstrating significant application potential in space solar power stations, lunar research base energy supply, and deep-space probe power systems. However, current domestic research remains at the ground-testing stage, lacking actual space-environment verification, while facing multiple challenges in complex space environment adaptability and optoelectronic device reliability. This paper addresses these issues by conducting preliminary design work on an intra-cabin LWPT system. Through establishing a 3D design model, we focus on mechanical resistance simulation analysis to evaluate structural stability under various load conditions. The results indicate that the proposed system exhibits excellent mechanical performance and feasibility, providing critical references for subsequent space-environment experimental validation.
