a housing having a first end and a second end and defining a cavity;
at least two electrodes extending into the cavity;
a solid-grain fuel material free of oxidizer and positioned in the cavity and exposed to the at least two electrodes, the fuel material having a combustion surface;
a combustion chamber defined between the combustion surface and the second end;
an oxidizer port arranged to provide a flow of an oxidizer to the combustion chamber;
a nozzle positioned at the second end;
wherein combustion of the fuel material in the combustion chamber is dominated by radiative heat transfer and maintains thrust of no more than 5 N at a flow rate of the oxidizer of no more than 5 g/s for a duration of at least between 1 and 15 seconds.
