A nano-jet micro-propeller, its preparation method and application

Abstract

The invention discloses a nano-jet miniature thruster and a preparation method and application thereof. The nano-jet miniature thruster comprises a glass nanotube, ion solution, a voltage adjustable power supply, a connecting mechanism and a baffle plate. One end of the glass nanotube is equipped with a sharp end. The ion solution is arranged in the glass nanotube. One end of the voltage adjustable power supply is connected with the sharp end of the glass nanotube, and the other end is connected with the baffle plate. The baffle plate is arranged at the outer side of the sharp end of the glass nanotube. The baffle plate is connected with the outer wall of the glass nanotube through a connecting structure. According to the nano-jet miniature thruster provided by the invention, the specific impulse is controllable; the thruster is flexible and simple and is low in cost; a voltage value is adjustable; different thrusts can be generated under different jet voltages, thereby achieving different motion states; array mounting can be carried out on a micro-nano satellite, thereby providing relatively high thrusts and carrying out adjustment in different directions; and a size of the glass nanotube is small, so the precision achieved by the thruster is high, thereby realizing high-precision control.

Description

technical field [0001] The invention relates to the field of micro-propellers, in particular to a nano-jet micro-propeller, its preparation method and its application. Background technique [0002] With the development of modern aerospace technology, satellites are developing in the direction of miniaturization, especially with the emergence of micro-nano satellites, micro-propellers, as an important part of micro-nano satellites, can realize the orbit change and attitude adjustment control of micro-nano satellites and space braking. The current micro-propulsion can be mainly divided into fuel propulsion, fuel-free propulsion and electric drive, and micro-propulsion is developing in the direction of miniaturization, light weight and modularization. There are mainly the following types of mainstream micro-propeller manufacturing: one is the miniaturization of traditional propellers, mainly including gas propulsion, miniature ion engines and solid-state rocket engines; the ot...
