Subsurface Lunar Electromagnetic Launcher for Industrial Payload Transfer to Earth: Design, Simulation and Practical Feasibility

This paper presents a ۲۰ km subsurface electromagnetic launcher for industrial payload transport from the lunar surface to lunar orbit and subsequently to Earth. The system employs a segmented coil architecture with distributed capacitor banks to enable controlled, high-efficiency acceleration while mitigating lunar dust, thermal fluctuations, and micrometeoroid impacts. Payloads ranging from ۵۰۰ kg to ۵ tons can be accelerated along the inclined exit trajectory to lunar orbit, after which auxiliary thrusters facilitate Earth transfer, leveraging Earth's gravity to minimize propellant consumption. Upon atmospheric entry, reverse thrusters and parachute deployment ensure safe capsule recovery. Mathematical analyses of kinetic energy, electromagnetic force, required magnetic field, and pulsed power confirm the technical feasibility of the system. Compared to conceptual NASA mass driver studies, the proposed architecture introduces several innovations: subsurface installation for structural stability, hybrid acceleration with partial electromagnetic launch and thruster insertion, modular design for maintenance, and integrated economic assessment, demonstrating substantial cost reduction per kilogram relative to full chemical launches. Advanced engineering considerations, including acceleration profiles, thermal management, structural stress analysis, and operational safety protocols, establish a framework for prototype development and industrial-scale implementation. Overall, this research demonstrates a practical, industrially scalable lunar mass driver system that combines engineering, operational, and economic considerations. The proposed architecture not only extends existing concepts but also provides a foundation for sustainable lunar industrial infrastructure, serving as a reference for future high-capacity payload delivery systems.
