An apparatus and method to electrocatalytically induce the decomposition of a liquid propellant for propulsion. This is accomplished by providing a reaction chamber filled with catalyst that has a first electrode, such as near the center, and the other electrode disposed away from the first electrode. A charge source that is capable of applying voltage is connected to the electrodes. When the reaction chamber is dosed with a propellant such as an aqueous based amine propellant, such as HAN, an electric current flows between the electrodes and the propell...


1. A propellant reaction ignition system, comprising: a reaction chamber adapted to receive a hydroxylammonium nitrate-based liquid propellant;a non-heated catalytic bed disposed within said reaction chamber, said catalytic bed being non-electrically conductive and having a first portion and a second portion;a first electrode secured within said first portion of said catalytic bed;a second electrode having an opposite polarity from said first electrode, said second electrode secured to said second portion of said catalytic bed and disposed away from said...
