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

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...
