Arcjet Thruster

An electrothermal thruster that passes propellant through an electric arc, heating it far beyond what a chemical reaction alone allows before it expands through a nozzle. Arcjets have flown operationally for satellite station-keeping, offering higher exhaust velocity than cold-gas or simple resistojet systems.

Highlights

  • Propellant superheated by an electric arc
