Abstract

The invention provides a filling device of a liquid propellant and a method thereof. The filling device of the liquid propellant comprises a high-pressure air source device, a pressurizing device of a transit storage tank, a propellant transfer filling device, a propellant blow-off device, a pressure relief device, the transit storage tank and a propellant storage tank. The device adopts a pressure difference method to carry out filling of the liquid propellant. The pressurization of the transit storage tank and blow-off of the propellant use high-purity nitrogen; the pressure relief device guarantees the pressure difference of the transit storage tank and the propellant storage tank so as to guarantee the normal proceed of the filling process; and the pressure relief device can relief the pressure of the pipeline so as to guarantee the test safety. The filling device of the liquid propellant and the method thereof also can be used for other occasions of liquid transferring.

Description

technical field [0001] The invention belongs to the field of electric arc heating engines, and in particular relates to a liquid propellant filling device and a method thereof. Background technique [0002] The arc-heating engine Arcjet has the advantages of high specific impulse, small thrust, high control precision, and simple structure, and is widely used to undertake tasks such as position maintenance and orbit control of geostationary satellites and low-to-medium orbit satellites. [0003] Using hydrazine as the propellant of the arc engine can not only achieve higher performance, but also share the propellant storage tank and valve with the chemical propulsion device, which can make the structure of the propulsion device simpler and lighter, so it has more advantages in engineering applications . Hydrazine is widely used as propellant in low power arc heating engines developed at home and abroad. Hydrazine propellant is toxic and volatile, so a specially designed fil...
