摘要
An atmosphere-breathing pulsed plasma thruster includes an inlet, a discharge section with an anode in fluid communication with the inlet, and a nozzle in fluid communication with the discharge section. Electrode assemblies extend radially through the discharge section and include a second electrode in the discharge section and an elongate portion extending outwardly. An electrode control mechanism moves the plurality of electrode assemblies between an inner position nearer to the anode and an outer position farther from the anode. At least one igniter extends between the anode and a cathode. An ignition circuit connects the anode and the cathodes to a first source of electric energy, and connects the igniter to a second source of electric energy through a controllable switch. A processor controls the position of the second electrodes, for example, in response to changes in atmospheric pressure.
