The invention provides a propellant management device for an embedded force-bearing storage tank. The propellant management device comprises a storage tank, the storage tank comprises a mounting flange vertically embedded into a cabin section, and a propellant management assembly is arranged in the storage tank; the propellant management assembly comprises a starting basket, a center cylinder, first accumulating blades and second accumulating blades, a liquid outlet pipe is arranged at the bottom of the starting basket, and the center cylinder is arranged at the top of the starting basket; and a plurality of first accumulating blades are arranged on the outer side wall of the center cylinder around the center axis of the center cylinder at intervals, a plurality of second accumulating blades are also arranged on the outer side wall of the center cylinder around the center axis of the center cylinder at intervals, the size of the second accumulating blades is larger than that of the first accumulating blades, and the number of the second accumulating blades is smaller than the number of the first accumulating blades. A three-stage accumulation area is formed by matching the plurality of first accumulation blades, the plurality of second accumulation blades and the starting basket, and the management efficiency of the propellant in the storage tank is improved under the condition that the flange section of the storage tank vertically bears external pressure.
Description
technical field [0001] The invention relates to the field of aerospace technology, in particular to a propellant management device for an embedded load-bearing storage tank. Background technique [0002] In the known technical field, the storage tank is an important part of the propulsion system, and its main function is to store liquid propellant and provide fuel for the power system. According to the mission characteristics of the aircraft, the storage tanks selected by some aircraft are required to bear the load together with the entire cabin. At this time, the propellant management device inside the tank needs to adapt to the installation structure of the tank, and can also realize the requirements of effective transmission, storage and continuous supply of on-orbit propellant. [0003] Under microgravity conditions, during the process of orbit change or attitude adjustment of the aircraft, the high-pressure gas-liquid propellant interface in the storage tank will under...
