Abstract

A connector and a cryogenic rocket system provided by the present invention include: a first connection structure, including a first panel, and a first liquid channel and a plurality of first gas channel channels arranged on the first panel; a second connection structure , including a second panel, the second panel is in contact with the first panel, the second panel is provided with a second liquid channel and a number of second gas channels, the second liquid channel is connected with the first liquid channel, the second The air passage is communicated with the first air passage; the locking piece, passing through the first panel and the second panel, has a locking state for fixing the first panel and the second panel and a separation state for unlocking the first panel and the second panel . This arrangement realizes the effective communication and integration of multiple air passages and liquid passages on a single connector, reduces the number of connectors, realizes the simultaneous communication or isolation of air passages and liquid passages, and improves the performance of the connector. The separation reliability of the system or device is simple in structure and easy to realize.

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...
