Development Of A Kmno4 Catalyst-Infused Fuel Grain For H2o2 Hybrid Thruster Ignition Enhancement, Ryan Thibaudeau, Stephen A. Whitmore

Small Satellite Conference

Utah State University's patented High Performance Green Hybrid Propulsion (HPGHP) technology leverages unique dielectric breakdown properties of 3D-printed acrylonitrile butadiene styrene (ABS), allowing re-start, stop, and reignition. HPGHP works most reliably using gaseous oxygen (GOX) as the oxidizer but has experienced ignition reliability and latency issues when replaced high test hydrogen peroxide (HTP), which has a significantly higher storage density. This deficiency results from HTP's high decomposition energy barrier. Traditionally, inline external catalyst beds or GOX pre-lead burns are used to overcome this energy barrier to achieve ignition; however, the extra hardware required for these systems have inhibited their adoption …
