Microsatellites are now in vogue and a lot of and a variety of missions using them are progressed in the world, some of them require propulsion system to realize a highly precise attitude control or orbit transfer. In order to satisfy the requirements, we are developing Microsatellite-Friendly Multi-Purpose Propulsion System, MFMP-PROP, with capabilities of both mono-propellant and bi-propellant modes to provide both of small impulse bit and large delta-V, under the policies of Safety First, Border Free, Effective COTS, and Easy Scalability, based on the techniques of 60wt% Hydrogen Peroxide. We conducted captive tests of a thruster for mono-propellant mode under bi-propellant mode to confirm its stable ignition and continuous operation, and obtained performances under its pre-heating temperature and mixing ratio of hydrogen peroxide and ethanol, of 160 seconds of specific impulse at the highest.

This paper reports fundamental study on performance degradation, caused by solid catalyst, of 60wt% hydrogen peroxide thruster for small satellites. The chemical in-space propulsion system, with 60wt% hydrogen peroxide, has been proposed and developed based on three policies, safety first, border free, and effective COTS. Platinum based metal honeycomb solid catalyst has been installed to BBM of thruster, and the solid catalyst is one of cause to limit lifetime of the thruster. In this study, to understand degradation, comparison between observation results of solid catalyst surface by FE-SEM/EDS and thruster performance has been conducted. Small cracks have been observed on upstream surface. The evident growth of cracks has not been found; however, instability of response time has been confirmed.
