An arcjet rocket or arcjet thruster is a form of electrically powered spacecraft propulsion, in which an electrical discharge (arc) is created in a flow of propellant (typically hydrazine or ammonia).This imparts additional energy to the propellant, so that one can extract more work out of each kilogram of propellant, at the expense of increased power consumption and (usually).

Fundamentals of Electric Propulsion: Ion and Hall Thrusters March The research described in this publication was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
Reference herein to any specific commercial product, process, or service. A schematic of an arcjet thruster is shown below: cathode x anode/nozzle r. arc m. V p. These devices take advantage of the channel constriction created by an arc to improve the thruster performance.
To see how this is possible, consider the Arcjet thruster research and technology book distributions of tem perature and density at some cross section of the Size: KB. Another potentially viable electrothermal propulsion system is the arcjet thruster.
This propulsion system relies upon a centrally located cathode surrounded by an anode; a high voltage electric field is generated between the cathode and anode, while the propellant is injected between the two electrodes (Jordan, ).
In spacecraft propulsion, a Hall-effect thruster (HET) is a type of ion thruster in which the propellant is accelerated by an electric field. Hall-effect thrusters use a magnetic field to limit the electrons' axial motion and then use them to ionize propellant, efficiently accelerate the ions to produce thrust, and neutralize the ions in the -effect thrusters (based on the.
