power source and discharge across the resistive element 235 to provide sufficient heat to the portion of the catalyst bed 245 and aid the reaction of the monopropellant 250 this discharge by capacitor 230 may cause a rapid thermal increase of the portion of the catalyst bed 245 associated with resistive element 235 once the catalyst bed 245 and thus the reactor 135 has reached a predetermined thermal point the monopropellant 250 may be injected through the reactor 135 so that monopropellant 250 comes into contact with the now heated catalyst bed 245 resulting in the rapid decomposition of the monopropellant 250 the hot gas 255 exhaust from reactor 135 may then be used in a manner similar to that of the conventional epu design as it is passed into a turbine fig1 referring now to fig3 a method 300 of igniting a monopropellant in the presence of a catalyst bed is described the method 300 may comprise a number of steps a resistive heating element may be provided for a portion of the catalyst bed according to block 310 the heating element may be associated with only a portion of the catalyst bed without providing heat for the entire bed since it may only be necessary to initiate the reaction at a single point a capacitor may then.
