Multiple Spark Plugs Approach for Pulsed Plasma Thrusters Assisting Resilient Proliferated Space Systems

Propulsion systems aboard small satellites assisting dynamic space missions at the proximity of deep space natural objects may face challenges in long-term non-serviceable operations, achieving thrust vector direction control, and adapting to severe environmental conditions. The proposed solution involves using pulsed plasma thrusters with multiple spark plugs for uniform ignition and thrust vector control, enhancing reliability and efficiency of propulsion system. Key advantages of the use of such an approach include minimal power consumption, efficient volume utilization, and enhanced reliability through redundant ignition points. Experimental validation confirms the effectiveness of the proposed architecture, demonstrating uniform ignition patterns and capability of thrust vector adjustment. It can be supposed that this approach supports the viability of small satellites in future deep space missions, promising dynamic, resilient, and reusable proliferated space systems.
