Abstract

The invention relates to a liquid transport interface for on-orbit autonomous refueling of a satellite and belongs to the technical field of on-orbit refueling of satellites. The liquid transport interface comprises an active end on a service satellite and a passive end on a target satellite; when the active end of the interface for on-orbit refueling is axially fed to a certain position, balls fall into a locking groove of the passive end of the interface, a solenoid valve is powered on to work, and the armature of a locking device of the active end presses the balls into the locking groove of the passive end of the interface, so that locking of the active end and the passive end of the interface for on-orbit refueling is achieved. After refueling is finished, the solenoid valve is powered on again, a valve core moves in reverse, the steel balls get out of the groove under the action of axial forces from springs, so that fast separation of the active end and the passive end of the interface for on-orbit refueling is achieved.

Description

technical field [0001] The invention relates to a liquid transmission interface for satellite on-orbit autonomous filling, and belongs to the technical field of satellite on-orbit filling. Background technique [0002] Satellite propellant on-orbit filling technology is one of the key technologies to prolong the life of satellites and reduce the cost of developing and utilizing space resources. On-orbit refueling technology can improve the satellite's payload carrying and orbital maneuverability, and prolong the satellite's in-orbit life. NASA has completed a demonstration test of the automatic on-orbit refueling process in the "Orbital Express" program, verifying its feasibility. With the continuous development of my country's satellite industry, in order to improve satellite performance and reduce satellite maintenance costs, a "space fuel station" must be established in space in the future, and on-orbit refueling is an essential technology for realizing this concept. ...
