Abstract

The invention provides a connector and a low-temperature rocket system, and the connector comprises a first connection structure which comprises a first panel, a first liquid path channel and a plurality of first gas path channels arranged on the first panel, a second connecting structure, a locking piece; the second connecting structure comprises a second panel, the second panel abuts against the first panel, the second panel is provided with a second liquid path channel and a plurality of second gas path channels, the second liquid path channel is communicated with the first liquid path channel, and the second gas path channels are communicated with the first gas path channels; and the locking piece penetrates through the first panel and the second panel and has a locking state for fixing the first panel and the second panel and a separating state for unlocking the first panel and the second panel. By means of the arrangement, effective communication and integrated arrangement of the multiple gas path channels and the multiple liquid path channels on the single connector are achieved, the number of the connectors is reduced, simultaneous communication or separation of the gas path channels and the liquid path channels is achieved, the separation reliability of a system or device where the connectors are located is improved, the structure is simple, and implementation is easy.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a connector and a cryogenic rocket system. Background technique [0002] Cryogenic rocket refers to the carrier rocket whose engine uses cryogenic propellant. As the cryogenic propellant of liquid rocket engine, such as liquid hydrogen, liquid oxygen or methane, it has the characteristics of low temperature and high performance. Cryogenic rockets need to be filled with propellant and provide the necessary gas before launch, and the arrow-ground connector is the key equipment to ensure that the propellant and gas are delivered to the cryogenic rocket. [0003] All connectors need to fall off reliably before the rocket is launched. In the existing technology, the low-temperature filling connector adopts pneumatic claw connection, and the gas and liquid are connected to the rocket body and the filling gas supply system through different connectors, and the structure is relatively...
