摘要： Systems and methods can support a plasma propulsion system. The system may include a thrust head comprising a plasma generator and a thrust generator. A propellant handling assembly may be directly coupled to the thrust head. The propellant handling assembly may comprise a manifold and a plurality of valves. A propellant storage vessel may be directly coupled to the propellant handling assembly. A propulsion control module may be operable to receive inputs associated with the plasma propulsion system, generate control outputs associated with the plasma propulsion system, establish and train models relating the inputs and the control outputs, apply the inputs to the models to update the output parameters, and apply the output parameters to control the plasma propulsion system.

摘要： An electrospray thruster and methods of manufacturing such thrusters are provided. The micro-electrospray thruster increases the thrust density of conventional electrospray thrusters by miniaturizing the individual components of the thruster thereby allowing for the increase in the number and density of the charged particle emitters.

摘要： An electric thruster has at least a portion of a surface of at least one of the component elements of its housing surface treated to increase the thermal transmission at the surface. The surface treatment is selected to increase the thermal absorption and thence the absorption of heat at the interiorly facing surfaces of the treated component, and/or to increase the thermal emissivity and thence radiation heat loss at the exteriorly facing surfaces of the treated component, and/or to increase the effective surface area through which heat is absorbed or emitted. The surface-treated housing components are assembled together with a cathode assembly, an ionization chamber, a propellant gas source, and a magnetic structure to form an electric thruster.

摘要： Systems and methods for embedding a thermal management system in an electric propulsion (EP) system is presented. According to one aspect, one or more oscillating heat pipes (OHPs) are provided within functional elements of the EP system. Each OHP includes channel segments that include a sealed working fluid. The channel segments are joined to form a continuous serpentine channel with a channel path that alternates between hot and cold regions of the EP system. According to another aspect, the functional elements of the EP system are reduced to a single monolithic structure with an embedded OHP. The single monolithic structure may be a single material or a multi material. According to yet another aspect, the functional elements are elements of a magnetic circuit of the EP system, including one or more of a backplate, an outer pole, an inner pole, or a center pole.

摘要： Systems and methods that employ a phase change material to provide thermal control of electric propulsion devices (thrusters). A spacecraft is configured to have an electric propulsion thruster. The electric propulsion thruster is surrounded with a phase change material. Suitable phase change materials include high-density polyethylene (HDPE), waxes, paraffin materials, and eutectic salts. The spacecraft is launched into orbit. The electric propulsion thruster is fired for a predetermined period of time. Heat generated by the electric propulsion thruster is absorbed and stored in the phase change material while the thruster is firing. The stored heat is dissipated into space after the thruster has stopped firing.

摘要： An ion thruster has a hollow cathode assembly including a heater with an inner ceramic sleeve and an outer ceramic sleeve. The outer ceramic sleeve overlies the inner ceramic sleeve with a filament volume between the two sleeves. A wound filament has windings disposed within the filament volume, and a mass of ceramic powder fills the remaining portion of the filament volume between the windings of the filament. A cathode is disposed within the inner ceramic sleeve of the heater. The heater is assembled by preparing the filament and forming it into a wound cylinder, and then encapsulating it and the powder between the inner and the outer ceramic sleeves. The hollow cathode assembly may serve as a portion of a plasma source or as a portion of a charge neutralizer.
