AI Technical Summary
Existing ultra-low orbit air-breathing electric propulsion technology suffers from low efficiency and high cost when utilizing rarefied gases, as the oxygen content in the gas can damage components such as electrodes and neutralizers, making it difficult to meet the requirements of green aviation.
The gas selective separation supply structure is adopted to separate the inhaled gas into components and supply them to different gas supply channels through the ionization zone in the Hall thruster, avoiding direct contact between oxygen components and electrodes. Combined with the gas enrichment and transfer unit and the separation supply unit, the gas is separated and recombined by temperature and pressure differences, thereby improving utilization efficiency.
It effectively avoids component damage, improves gas utilization efficiency, reduces operating costs, and achieves efficient utilization of environmental gases.
