Abstract

The invention discloses a working medium supply device for a self-heating type electric propeller and the electric propeller. The working medium supply device for the self-heating type electric propeller comprises a working medium storage tank, a flow valve, a first pipeline and a second pipeline, wherein a vertical section of the working medium storage tank is in a groove shape; the flow valve, the first pipeline and the second pipeline are arranged in the groove; an air inlet of the flow valve is communicated with the inner part of the working medium storage tank through the first pipeline;an air outlet of the flow valve is communicated with a discharge chamber arranged in the groove through the second pipeline. According to the working medium supply device for the self-heating type electric propeller and the electric propeller, provided by the invention, power consumption of the electric propeller is reduced and the problem that steam is easily and locally condensed is avoided.

Description

technical field [0001] The invention relates to the technical field of aerospace electric propulsion, in particular to a self-heating electric thruster working medium supply device and an electric thruster. Background technique [0002] With the rapid development of aerospace propulsion technology, electric propulsion technology, which uses ions or plasma jets generated after ionization of the working gas to generate reverse thrust, has the advantages of high specific impulse, convenient portability, and light weight in the application of micro-nano satellites. Gradually occupy a place in the. The development of xenon electric propulsion technology represented by ion propulsion and Hall propulsion is relatively mature. The propulsion system adopts a high-pressure gas propellant storage system, which has problems such as heavy dryness of the storage system, low storage density of xenon gas, and large storage tank volume. Based on this, the propulsion technology of solid-stat...
