An on-orbit supplementary gas-liquid interface device

Abstract

The invention relates to a connector device for replenishing gas and liquid on the orbit. The connector device is used for replenishing gas and liquid for a target satellite by a service satellite on the orbit. The connector device comprises an active mechanism and a passive mechanism. The service satellite and the target satellite are positioned and conveniently separated through guide devices on respective butt-joint surfaces of the active mechanism and the passive mechanism, the service satellite and the target satellite are caused to move relative to each other through a drive mechanism having the axial spacing function, and the service satellite and the target satellite are locked through a positioning locking structure, so that the service satellite and the target satellite are guaranteed to be at fixed positions relative to each other in the on-orbit gas-liquid replenishing process. Through the measures, the efficiency of the on-orbit gas-liquid replenishing process is improved, and the safety of the on-orbit gas-liquid replenishing process is guaranteed.

Description

technical field [0001] The invention relates to an interface device, in particular to an on-orbit supplementary gas-liquid interface device, which belongs to the field of on-orbit propellant supply services. Background technique [0002] On-orbit propellant replenishment is a key problem to be solved for on-orbit service, and on-orbit propellant replenishment is a current international research hotspot for on-orbit service. According to the space experiments conducted by foreign in-orbit services and the planned research in progress, more than 50% of the projects are related to on-orbit propellant replenishment. On-orbit propellant replenishment can effectively prolong the life of the on-orbit vehicle, and it is a content that best reflects the economic benefits of on-orbit services. The on-orbit supplementary test project carried out by the International Space Station has laid a technical foundation for future independent on-orbit supplementary missions. In the major proj...

Problems solved by technology

my country's high-orbit dual-component satellites usually adopt a load-bearing barrel structure. For satellites with this structure, it is difficult to arrange an inter-satellite docking mechanism that can complete the double-star fixed connection function on its outer surface.

This is because the inter-satellite docking structure requires the mounting surface to provide sufficient space and strength, and the two mounting surfaces (facing the ground and being grounded) with the highest strength of the load-bearing bucket structure satellite are respectively occupied by orbital control engines and various antennas, which cannot Provide sufficient installation space for the inter-satellite docking mechanism, while the structural strength of the remaining four surfaces cannot withstand the impact and interaction force generated by the docking mechanism connecting the two satellites
