AI Technical Summary
Existing technologies struggle to achieve gas-liquid separation and gas-free discharge from propellant tanks under microgravity conditions, especially at low speeds or low flow rates, leading to liquid entrainment during on-orbit refueling.
It employs large and small blade assemblies, combined with blade positioning shafts and liquid collector assemblies, and drives the liquid through a plug-in structure and surface tension under microgravity. It utilizes plate-type liquid management technology to achieve gas-liquid separation. The blades are designed with a hollow structure in the middle to reduce weight and suppress liquid sloshing.
It achieves effective gas-liquid separation and gas-free discharge under microgravity conditions, optimizes structural weight and reliability, and ensures the stability of on-orbit refueling of propellant tanks and the effect of liquid-free venting.
