摘要： A propulsion unit (10) for a spacecraft is described. The propulsion unit (10) comprises a centrally arranged cathode (20), a concentric anode (30), an injection point (60) for injecting a propellant (50) between the central cathode (20) and the concentric anode (30), an acceleration coil system (100) and a vectoring coil system (110) for expelling a plasma plume (75) from a nozzle (115). A plurality of superconducting coils (120, 125) is arranged about the concentric anode (30) for creating a magnetic field (B) between the central cathode (20) and the concentric anode (30) and directing the plasma plume (65) from the nozzle (115).

摘要： A Hall effect thruster including: a discharge channel with an open downstream end; a cathode situated outside the discharge channel; an injector system configured to inject atoms of gas into the discharge channel, the injector system situated at an upstream end of the discharge channel and also forming a cathode; a heater device configured to heat the cathode; a measurement mechanism measuring temperature of the heater device, and a regulator circuit regulating the temperature such that the heater device heats so long as its temperature is less than a threshold temperature from which the thruster is capable of starting, and ceases to heat shortly after the threshold temperature has been reached.

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： The present invention provides a hall-type electric propulsion that exhibits both overheating protection and operational stability, thereby simultaneously solving the problem of waste heat, which worsens with micronization, and the problem of discharge current oscillation. First, the magnetic flux distribution in ionization/acceleration channel is formed to optimize ion velocity vector, whereupon a propellant flow passage (propellant conduit) is disposed in a magnetic pole of the propulsion, or more specifically in the vicinity of the acceleration channel, and then propellant is passed through the flow passage. Thus, the magnetic pole, which is overheated by the generated plasma, can be cooled, and at the same time the propellant can be heated. Furthermore, the heated propellant is choked immediately before being introduced into the ionization/acceleration channel by a throat region provided immediately before the ionization/acceleration channel, and as a result the sonic speed of neutral species (propellant) is increased.
摘要翻译：本发明提供一种展示过热保护和操作稳定性的霍尔型电动推进器，从而同时解决了随着微粉化而恶化的废热问题和放电电流振荡的问题。首先，形成电离/加速通道中的磁通量分布，以优化离子速度矢量，由此将推进剂流动通道（推进剂导管）设置在推进的磁极中，或者更具体地在加速通道附近，以及然后推进剂通过流道。因此，可以冷却由所产生的等离子体过热的磁极，同时可以加热推进剂。此外，加热的推进剂在被离子化/加速通道之前提供的喉部区域引入离子化/加速通道之前立即窒息，结果中性物质（推进剂）的声速增加。

摘要： An electric propulsion device is disclosed having an anode and a cathode. The propulsion device includes a discharge annulus having the anode adjacent an end region thereof. At least one inlet aperture is adjacent the anode, the aperture(s) having propellant gas flow therethrough into the discharge annulus. The propellant gas has an ionization potential. Opposed, dielectric walls define the annulus, with at least one of the opposed dielectric walls having pores therein, the pores having cooling gas flow therethrough into the discharge annulus and substantially adjacent the opposed dielectric wall(s). The cooling gas has an ionization potential higher than the ionization energy of the propellant gas. The cooling gas is adapted to substantially prevent at least one of secondary electron emission and sputtering of the dielectric walls.

摘要： A plasma arc thrustor including a hollow core formed from an electrically conductive substance capable of withstanding extremely high temperatures, and radiation flanges engaging the core and formed from a different but lighter material which is capable of conducting heat away from the core. An arc is maintained between an electrode in the hollow portion of the core and a composite electrode consisting of the core and one of the radiation flanges. A coil is located in offset relation to the arc, and radiation shields are interposed between the coil and the radiation flanges.
