Abstract

The invention provides a device for balanced discharge of parallel storage tanks. The device comprises a volumetric flow meter A (2), a volumetric flow meter B (4) and a rigid interconnection mechanism (3), whereina main shaft of the volumetric flow meter A (2) is connected with a main shaft of the volumetric flow meter B (4) through the rigid interconnection mechanism (3). The device for balanceddischarge of parallel storage tanks has the advantages of being high in flow control precision, wide in pressure application range and high in viscosity adaptability, flow calibration can be completed in a single-machine state, system pipeline matching and system cold flow testing do not need to be conducted, system testing and structural layout are simplified, and product reliability is greatlyimproved.

Description

technical field [0001] The invention relates to the technical field of space propulsion systems. In particular, it relates to a device for balanced discharge of parallel storage tanks. Background technique [0002] During the working process of the spacecraft, there will be differences in the mass of propellant consumption in the two parallel storage tanks of the same component, and this difference is called the unbalanced discharge amount of the parallel storage tanks. Due to the unbalanced propellant consumption of the symmetrically arranged storage tanks, the center of mass of the spacecraft is constantly shifted during flight, which may cause the spacecraft to deviate from the flight track. In order to correct the flight deviation of the spacecraft, the attitude control engine needs to work continuously, consume too much propellant, so that the propellant is exhausted in advance; if the serious imbalance exceeds the ability of the attitude control engine to adjust the a...
