Problems solved by technology
[0002] The bubble break point is one of the key characteristic parameters of the surface tension tank. If the bubble break point of the tank is too low, the propellant output from the tank will be entrapped with gas. As a result, the propellant management capability will be reduced or the propellant supply flow will be insufficient. Lead to performance degradation or complete failure of the attitude and orbit control power system
At present, the test of the bubble break point of the storage tank can only be carried out in the state of the management device components, but after the management device components are loaded into the storage tank, it is completely invisible, and the traditional test method cannot be carried out

The invention provides a surface tension storage tank bubble breaking point testing method and system. The surface tension storage tank bubble breaking point testing method comprises the steps:1, soaking a screen in a surface tension storage tank completely according to a testing preparation device; and 2, measuring a surface tension storage tank bubble breaking point value according to the testing device. According to the system, the surface tension storage tank bubble breaking point is measured by adopting a reasonable operation method, so that the problem that the surface tension storage tank bubble breaking point cannot be measured can be solved; the method has the advantages of simple operation, low cost, high test precision and the like, and can be used as a surface tension storage tank bubble breaking point testing method in aerospace products such as satellites and the like.
Description
Technical field [0001] The invention relates to the field of aerospace technology, in particular to a method and system for testing the bubble break point of a surface tension tank. Background technique [0002] The bubble break point is one of the key characteristic parameters of the surface tension tank. If the bubble break point of the tank is too low, the propellant output from the tank will be mixed with gas, which will result in a decrease in the propellant management capability or insufficient propellant supply flow. Causes the performance of the attitude and orbit control power system to decline or completely fail. At present, the test of the broken point of the tank bubble can only be performed in the state of the management device component, but after the management device component is installed in the storage tank, it is completely invisible, and the traditional test method cannot be performed.
