Problems solved by technology

Considering the complex tasks, time urgency, and large propellant dose during the orbit change, the above methods are not suitable for measuring the unbalanced discharge of parallel storage tanks during the orbit change.
In addition, the error of the unbalanced quantity obtained by the indirect method doubles the error of the original remaining quantity measurement method, and it is difficult to obtain a measurement result with high precision

Abstract

The invention provides a device and a method for measuring unbalanced discharge of orbital transfer parallel storage tanks of a high-orbit satellite. The device comprises a plurality of liquid level sensor groups, wherein each liquid level sensor group comprises a plurality of liquid level sensors, the plurality of liquid level sensors in the same group are respectively arranged at the same height position in the axial direction of the parallel storage tank, and the direction of a heating belt in each liquid level sensor is vertical to the axial direction of the storage tank; and the storage tank is wrapped by multiple layers of heat insulation assemblies. According to the invention, the problem of direct measurement of unbalanced discharge of the parallel storage tanks in the orbital transfer process is solved, and the beneficial effects of simple structure, easy implementation, low cost, good timeliness, strong anti-interference capability, strong adaptability, high popularization value and the like are achieved.

Description

technical field [0001] The invention relates to the field of spacecraft propulsion systems, in particular to a device and method for measuring unbalanced discharge of high-orbit satellite orbit-changing parallel storage tanks. Background technique [0002] Domestic satellite platforms such as SAST5000 and DFH-5 all adopt a four-tank tile layout, and the same propellant is stored in two parallel tanks. An important problem faced by parallel tanks is the unbalanced discharge of the two tanks during use. If the propellant discharge of the parallel storage tanks is unbalanced, it will cause the center of mass of the satellite to shift, and in severe cases, the attitude can not be controlled when the orbit change engine is ignited; when the propellant in one storage tank is emptied, the remaining The propellant becomes unusable and becomes sluggish. [0003] Measuring and obtaining the unbalanced discharge of parallel storage tanks is the premise of unbalanced discharge adjustm...
