Embodiment Construction

[0026] like figure 1 As shown, the present invention is specifically composed of a high-pressure air source device, a pressurizing device, a manipulation air device, a blowing device and a liquid propellant supply device.

[0027] The high-pressure gas source device mainly includes a high-purity nitrogen gas cylinder 1 and a gas cylinder pressure gauge 2, which are used to provide stable high-pressure gas for liquid propellant filling. The high-purity nitrogen gas cylinder 1 provides a high-pressure gas source with a nitrogen purity of 99.99%. The gas cylinder pressure gauge 2 monitors the high-purity nitrogen pressure in the gas cylinder. When the high-purity nitrogen gas pressure in the high-purity nitrogen gas cylinder 1 is less than 5MPa, the high-purity nitrogen gas cylinder 1 should be replaced. The high-purity nitrogen gas cylinder 1 is equipped with a cylinder manual valve to control the supply of high-pressure gas.

[0028] Make sure all valves are closed before pro...

Abstract

The invention provides a pressure stability control device supplied with constant voltage by a propellant, in particular comprising a high-pressure air supply device, a supercharging device, a control gas device, a blowing device and a liquid propellant supplying device. The high-pressure air supply device supplies high-pressure air. The supercharging device supercharges a propellant storage tank to extrude the propellant to enter a feeding pipeline, and a supercharging buffer tank can stabilize the pressure of pressurized gas. The blowing device is in charge of filling the clearing of pipeline propellant. The control gas device provides control gas for the system. The pressure of pressurized gas can be always kept constant by the pressure stability control device supplied with constant voltage by the propellant, thereby continuously supplying liquid propellant in testing, and satisfying the principle of slow supercharging and preventing collapse of the feeding pipeline due to too fast pressurizing in pressurization.

Description

technical field [0001] The invention belongs to the field of electric propulsion engines, in particular to a control device for providing constant pressure during liquid propellant supply in electric propulsion engines such as resistance heating engines, Arcjet arc heating engines, ion engines, MPD thrusters and other electric propulsion engines. Background technique [0002] Electric propulsion engines have the advantages of high specific impulse, long life, repeatable starting, and high control accuracy, and have broad application prospects in spacecraft attitude and orbit control, deep space exploration, interstellar navigation and other tasks. The application of electric propulsion technology will effectively increase the payload of the spacecraft, reduce the launch cost, and improve the overall technical level of the spacecraft. Therefore, research on electric propulsion engines through ground tests is being carried out extensively. [0003] Resistance heated thrusters...
