Abstract

The invention discloses an efficient full-management device for a surface tension storage tank propulsive agent, belongs to the technical field of space propulsion and particularly relates to a management device used for a satellite propulsion system propulsive agent. Four axial pipelines are arranged and are evenly distributed in the circumferential direction, and two axial hydraulic accumulatorsare installed on each axial pipeline; and the four axial pipelines are redundancy backup mutually, and it can be ensured that the propulsive agent is conveyed into the management device stably underthe micro-gravity environment as long as lone channel is connected with liquid. By means of the efficient full-management device, a ring-shaped channel and the axial channels are installed and fixed to a crossed-shaped supporting frame, the ring-shaped pipeline is of a circular ring pipe-shaped structure, the ring-shaped pipeline communicates with the axial channels through the crossed-shaped supporting frame, meanwhile, the crossed-shaped supporting frame can fix the axial channels and the ring-shaped pipeline, and rigidity of the whole management device is improved.

Description

technical field

[0001] The invention relates to a high-efficiency and complete management device for propellant in a surface tension storage tank, which belongs to the field of space propulsion technology, in particular to a management device for propellant in a satellite propulsion system. Background technique

[0002] At present, the efficient management technology of satellite propellants in orbit is still one of the hotspots in space propulsion research. Utilizing the principle of liquid driven by surface tension under microgravity, the net-type full-management technology that realizes the storage of gas-free liquid in the management device is the preferred technology for satellites with strong mobility and high acceleration. Mesh surface tension tank is the earliest surface tension tank used in orbit, and its use is a revolution in the development of satellite propellant tanks. Compared with conical storage tanks and diaphragm storage tanks, it has excellent performanc...
