Abstract

The invention provides a propellant management device for an embedded load-bearing storage tank, which includes a storage tank, the storage tank includes a mounting flange vertically embedded in the compartment, and a propellant management component is built in the storage tank; the propellant management component It includes a starting basket, a central cylinder, a first storage blade and a second storage blade. The bottom of the starting basket is provided with a liquid outlet pipe, and the central cylinder is arranged on the top of the starting basket; the first storage blade is on the outer wall of the central cylinder. There are a plurality of intervals around the central axis of the central cylinder, and a plurality of second storage blades are also arranged on the outer wall of the central cylinder around the central axis of the central cylinder, and the size of the second storage blades is larger than that of the first storage blades. The size of the second storage vane is smaller than the number of the first storage vane. The three-stage storage area formed by a plurality of first storage blades, a plurality of second storage blades and the starting basket is helpful to increase the propellant in the storage tank when the flange section of the storage tank is vertically subjected to external pressure. management efficiency.

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 internal propellant management device of the tank is required to adapt to the installation structure of the tank, and also be able to realize the requirements of effective transmission, storage and continuous supply of propellant on orbit. [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 stora...
