We introduce the novel concept of “Microsatellite-Friendly Multi-Purpose Propulsion (MFMP-PROP)'' as a pioneering low-toxicity propulsion system specifically tailored for microsatellites. Our ongoing research endeavors are focused on its modularization, a crucial step towards its practical implementation. The modular configuration of MFMP-PROP encapsulates all essential components of a propulsion system within a compact 1U form factor. Notably, this innovative design enables seamless operation in both monopropellant and bipropellant modes, affording microsatellites the flexibility to deploy small impulse bit and substantial thrust within a singular unit. Despite initial iterations falling short of performance targets outlined in preceding reports, our iterative approach has led to notable enhancements. Specifically, adjustments were made to the thruster's surface area, complemented by the incorporation of preheating mechanisms facilitated by dedicated heaters. This meticulous optimization process has yielded promising results, with MFMP-PROP now surpassing predefined benchmarks within the monopropellant mode, achieving a specific impulse exceeding 110 seconds. Such advancements underscore the efficacy and viability of our proposed propulsion system for microsatellite applications.
