Abstract

An electric propulsion test platform liquid propellant supplying device comprises a propellant transfer storage tank, a propellant storage tank, a flowing measuring device, a propellant pipeline device, a liquid propellant filling device and a high-pressure air supply device. The liquid propellant filling device is connected with the propellant transfer storage tank and the propellant storage tank, and connecting pipelines are provided with filling valves. The propellant flows into a propellant supplying pipeline from the propellant storage tank by means of storage tank pressurization, and enters an engine. After testing, the pressure inside the pipelines can be released via a pipeline release valve. The invention can accurately measure the flow rate of liquid propellant and the pre-spraying pressure at the time of engine functioning, and can simultaneously guarantee the safety of testing personnel at site in propellant supplying operation or other operations.
