Description

technical field [0001] The invention relates to the field of attitude control power system testing, in particular to a quantitative filling device and filling method for the attitude control power system. Background technique [0002] The propellant required for engine operation in the attitude control power system test must be filled into the storage tank in advance. The traditional filling method is to pre-evacuate the storage tank, and then use the pressure difference between the filling container and the storage tank to fill the propellant into the storage tank. During the filling process, the weight change of the filling container is Propellant charge. [0003] The quantitative filling of the attitude control power system puts forward higher requirements on the accuracy of propellant filling. Generally, the deviation is required to be within the range of ±150g or ±100g, while the traditional filling method ignores the change and increase of the filling pipeline constra...
