Magnetic ionic liquid thruster

Abstract

The invention discloses a magnetic ionic liquid thruster. The magnetic ionic liquid thruster comprises a storage unit, a magnetic induction unit, a power supply unit and an emission unit, wherein theemission unit comprises a plurality of emitter bases, extraction electrodes and accumulation electrodes, and magnetic sprayers positioned at the outer side of the thruster; the plurality of emitter bases, extraction electrodes and accumulation electrodes have the same quantities; the storage unit is used for storing magnetic ionic liquid; the magnetic induction unit generates magnetic induction force, so that a peak is formed on the surface of the magnetic ionic liquid entering the emitter bases from the storage unit; the power supply unit is used for providing electric pulses for the emitterbases, the extraction electrodes and the acceleration electrodes; the extraction electrodes enable the peak formed on the surface of the magnetic ionic liquid to spray ions and charged liquid drops ina direction towards the acceleration electrodes under the effect of electric pulses; the acceleration electrodes are used for accelerating the movement of the ions and the charged liquid drops in a direction towards the magnetic sprayers under the effects of the electric pulses; and the magnetic sprayers are used for spraying the ions and the charged liquid drops out of the thruster to generate thrust.

Description

technical field [0001] The present disclosure relates to a thruster, in particular to a magnetic ionic liquid thruster. Background technique [0002] Micro-nano satellites are an important direction for the development of satellites in the future. Micro-nano satellites have the advantages of low cost, short development cycle, strong expansion capability, and flexible launch methods. Task. However, with the increase in the complexity of tasks performed by micro-nano satellites and the increase in the design life in orbit, corresponding propulsion modules will be required to complete their attitude control and orbit maintenance tasks. [0003] The emitters of existing electrospray propellers are usually manufactured by conventional mechanical means. However, the machining accuracy of traditional machining methods is limited, generally only reaching the sub-micron level.

Problems solved by technology

However, the machining accuracy of traditional machining methods is limited, generally only reaching the sub-micron level

The density of the two-dimensional needle tip array or capillary array manufactured by processing is limited, which will affect the final thrust density generated by the thruster, making the manufactured equipment larger in volume and weight, difficult to expand the array, and less integrated and difficult to modularize design

And the problem with all of these structures is that the emitter can cause permanent damage, whether during manufacture, assembly and shipping, or during operation
