A plasma electrothermal thruster includes a capillary passage in which a plasma discharge is formed and directed out of an open end of the passage into a supersonic nozzle. Liquid supplied to the capillary passage becomes partially atomized to cool a confining surface of the passage. The plasma discharge is formed as the atomized liquid flows out of the open end into a supersonic equilibrium nozzle. The discharge can have a duration greater than the two way travel time of acoustic energy in the capillary to cause the plasma to flow continuously through t...
An electrothermal thruster adapted to be mounted on a mass to be propelled comprising means for forming a capillary passage having an elongated plasma confining surface that is an outer boundary for plasma in the passage, the passage having an open end, electric means for forming a plasma discharge in the capillary passage, the capillary passage being arranged so that the plasma is ejected from the capillary passage only out of the open end, the ejected plasma being a thrust source for the mass, the plasma in the capillary passage having a very high pres...
