Embodiment Construction

[0036] A non-thrust gas discharge device for on-rail filling of the present invention utilizes the principle of liquid driven by surface tension under microgravity, adopts the plate type liquid management technology and the characteristics of strong storage capacity at acute angles, and designs the gas-liquid separation chamber 4 and belt There are through-hole storage plate blades, and the combination of the two realizes the liquid storage function under microgravity, so as to realize the gas-liquid separation and achieve the purpose of exhaust without liquid inclusion. At the same time, the exhaust ports are arranged symmetrically, so that the thrust generated by the exhaust ports is mutual Offset, and ultimately complete in-orbit refueling without thrust gas emissions.

[0037] In the structure of the present invention, the fluid enters the gas-liquid separation chamber 4 from the inlet structure 1. Under the action of the pressure difference, the fluid flows to the area of ...

Abstract

The invention provides a thrust-free gas emission device for on-orbit refueling. The thrust-free gas emission device comprises an inlet structure, a gas-liquid separation chamber, an exhausting structure and a liquid discharging structure, wherein the gas-liquid separation chamber is used for separating gas flow to be discharged into gas and liquid by adopting a principle of driving liquid throughsurface tension under micro-gravity; the inlet structure is mounted at the top of the gas-liquid separation chamber and is used for enabling the gas flow to be discharged to flow into the gas-liquidseparation chamber; the exhausting structure is mounted on a side wall of the gas-liquid separation chamber and is used for exhausting gas; and the liquid discharging structure is mounted at the bottom of the gas-liquid separation chamber and is used for discharging the liquid. By utilizing the principle of driving the liquid through the surface tension under the micro-gravity, the characteristicof a strong acute angle retention capability is combined, and a gas-liquid separation chamber structure and a retention plate type blade with a through hole are designed so that liquid retention and no-liquid-carrying exhausting functions under the micro-gravity are realized; meanwhile, exhausting openings are symmetrically distributed so that the thrust generated by the exhausting openings is mutually balanced; and thrust-free gas emission under an on-orbit refueling condition is realized.

Description

technical field [0001] The invention relates to a non-thrust gas discharge device for on-orbit filling, which belongs to the technical field of gas-liquid separation, in particular to an exhaust device for satellite propellant storage tanks. Background technique [0002] At present, the satellite on-orbit refueling technology is still in the research and development stage in my country, and the non-thrust gas discharge of the propellant tank is the core technology of the on-orbit refueling system. There is no mature product application record for the non-thrust gas discharge device used in the on-orbit refueling system in my country. At present, centrifugal gas-liquid separation technology is mainly used for gas-liquid separation on the ground. Centrifugal gas-liquid separation technology is mainly realized by rotating parts or designing spiral flow channels, which cannot be realized when the rotation speed of rotating parts is low or the flow rate of spiral flow channels is...
