A kind of working medium flow supply amount adjustment device based on thermal throttle valve

Abstract

The invention discloses a thermal throttling valve-based adjusting device for working medium flow supply quantity. After high-pressure gas discharged by a high-pressure storage tank sequentially passes through a pressure adjusting module, a low-pressure storage tank and a low-frequency oscillating current heating loop, an ionization collision occurs inside a discharge channel of a gas distributorof a Hall Thruster, and low-frequency oscillating current is generated and wound on a first thermal throttling valve through a low-frequency oscillating current coil to generate a magnetic field; whena magnetic force line in the magnetic field passes through a metal valve element in the first thermal throttling valve, eddy current is generated, and the short-circuit heat effect is utilized to generate heat to enable the first thermal throttling valve to automatically emit heat at high speed; and when the temperature of the first thermal throttling valve rises, working medium gas flow of the first thermal throttling valve is reduced, so that the Hall Thruster achieves self-adaptive adjustment of the working medium flow supply quantity. According to the thermal throttling valve-based adjusting device for the working medium flow supply quantity, the weight and the size of a heating power supply of the thermal throttling valve of a thruster working medium flow supply system are saved, andthe self-adaptive adjustment of working flow of the Hall Thruster in orbit can be realized.

Description

technical field [0001] The invention relates to the field of adjusting the flow rate supply of a Hall effect electric thruster, in particular to a device for adjusting the flow rate supply of a working medium based on a thermal throttle valve. Background technique [0002] Due to its simple structure, appropriate specific impulse and high efficiency, Hall thrusters are widely used in space propulsion tasks such as satellite position maintenance and orbit change. The supply adjustment of the working gas flow during the Hall thruster generally includes the following processes: First, the high-pressure storage tank is deflated, and then the gas pressure is reduced by a pressure regulation module so that the gas enters the low-pressure storage tank, and then the low-pressure storage tank is released. The gas in the storage tank flows through a thermal throttling valve and enters the discharge channel through the gas distributor to collide with the electrons emitted by the cathod...
