Development of a lunar vehicle with a hybrid rocket engine produced using lunar resources

Abstract

This article presents a comprehensive study on the innovative use of in-situ lunar resources for the development of a hybrid rocket engine utilizing magnesium (Mg) and aluminium (Al), which are abundantly available in lunar regolith. The primary focus is on the feasibility and sustainability of using these metal oxides as primary fuels in propulsion systems specifically designed for lunar missions. The research encompasses the design phases of a lunar lander, highlighting the application of these metals in the engine design to facilitate efficient space travel between research stations on the Moon's surface. Detailed discussions cover the extraction and processing of Mg and Al directly on the lunar surface through adapted electrolysis processes suitable for the Moon's environment. The article also explores the engineering of a cryogenic tank system using native lunar materials to address the challenges posed by the Moon's extreme temperature fluctuations. A key component of the study is the simulation of simple trajectory calculations for travel between lunar research locations using the newly designed hybrid rocket engine. Theoretical analyses suggest that this metal-based propulsion technology could significantly enhance the logistical capabilities of lunar exploration missions, offering a viable solution for both crewed and uncrewed missions. The development of such technologies not only aims to reduce Earth dependence by utilizing lunar resources but also sets a precedent for future interplanetary travel infrastructure.
