Problems solved by technology

Although the design of the colloidal thruster is based on the physical phenomenon of the electrospray process, the structural parameters of the thruster such as the form of the emitter, the distance between the emitters, the distance between the emitter and the extractor, the size of the emitter and the propulsion The influence of the materials used in different components of the thruster on the performance of the thruster has not been considered in the design process of the thruster or has not been reported in detail
[0004] As far as domestic related technologies are concerned, industrial production and scientific applications such as mass spectrometry, combustion, and material synthesis are all based on the electrospray process. The detailed design of the jelly thruster has not been publicly reported

Abstract

The invention discloses a hole type multi-cavity colloid thrustor which comprises a multi-directional valve, stainless steel capillary pipelines, a storage tank, an insulating base, an insulating spacer, an insulating bolt, an accelerator, an extracting pole, a sunk screw and a PEEK pipeline; wherein, the multi-directional valve is connected with the stainless steel capillary pipelines and the PEEK pipeline, wherein, one PEEK pipeline is used for realizing one-way supply of propelling agent, and a plurality of stainless steel capillary pipelines are respectively connected between the multi-directional valve and the storage tank; the storage tank is connected with the insulating base by the sunk screw, and the sunk screw under the storage tank is locked by a nut; the insulating base is fixedly connected with the insulating bolt which is sequentially penetrated with the extracting pole, the insulating spacer and the accelerator, and the extracting pole, the insulating spacer and the accelerator are fastened with the insulating bolt by nuts; equidistant array through holes arranged on the insulating base are taken as channels, through which the propelling agent can flow out. The invention can conveniently form different types of thrustors in multiple ways, and realizes different adjusting ways of the performance of the thrustor, so as to meet the requirements of different performances.

Description

technical field [0001] The invention relates to a hole-type multi-cavity colloidal thruster, which belongs to the technical field of space micro-thrust engines. Background technique [0002] In recent years, the development of satellites has been based on the principles of low cost, high reliability, high simplification, and long life, and the use of micro-satellite constellations with relatively simple functions has replaced large satellites to perform comprehensive space missions. The application of micro-satellites puts forward new requirements for the propulsion system: not only the strict requirements of micro-impulse and micro-thrust, but also the restrictions on parameters such as weight, volume, and power. The micro-propulsion system can precisely change the position of the satellite and eliminate external micro-interference, and realize satellite constellation positioning and other requirements. Colloidal micro-thrusters and FEEP are the most systematically advanta...
