Development and Simulation of an Embedded Hydrogen Peroxide Catalyst Chamber in Low‐Temperature Co‐Fired Ceramics

Abstract

Satellites in the range of 10–50 kg require small propulsion devices to perform station‐keeping tasks in orbit. Low‐temperature co‐fired ceramic structures provide a unique platform to produce a reliable, low‐cost micropropulsion system. The design uses microchannels embedded in the ceramic substrate to create a nozzle and embedded catalyst chamber. A hydrogen peroxide monopropellant is injected into a silver‐coated catalyst chamber structure. The monopropellant decomposes into hot gas, which is expelled through the nozzle producing thrust. A thermal energy balance and a kinetic model is presented along with performance testing.
