AI Technical Summary
In existing ultra-low orbit air-breathing electric propulsion technology, the direct use of gas leads to oxidation damage to thruster components, resulting in short service life, difficulty in replacement, and impact on satellite orbit maintenance and maneuverability.
An electric propulsion device employing partitioned ionization divides the ionization zone into sections and sets up supply channels according to gas composition, supplying oxidizing and non-oxidizing gases separately. This prevents oxidizing gases from contacting critical components and, when used in conjunction with a neutralizer, improves the oxidation resistance of the components.
It effectively extends the service life of electric thrusters, reduces wear and replacement costs, and improves the reliability of their use in ultra-low orbit satellites.
