Abstract

The present invention provides a method and a device for designing the timing sequence of a carrier rocket's gas-liquid connector falling off before firing. The method includes: obtaining information of the connectors to be sorted from a database; setting the detachment time of the connectors whose detachment mode is manual detachment as the work end time; Sorting: first fill and then supply air, first at room temperature and then at low temperature, and set the detachment time of each connector according to the end of work; reorder according to the detachment time of each connector, and based on safety, reliability, reversibility and The external system coordination check adjusts the ordering, and obtains the disconnection timing of the connectors to be ordered. The invention realizes the automatic design of the connector detachment sequence; since the influence of the safety, reliability, reversibility and external system coordination of the connector on the detachment sequence is considered, the design method of the invention can improve the launching process of the liquid carrier model security and reliability.

Description

technical field

[0001] The invention relates to the technical field of carrier rockets, in particular to a method and device for designing the timing sequence of a gas-liquid connector of a carrier rocket before firing. Background technique

[0002] The gas-liquid connector is one of the important stand-alone equipment in the pre-launch process of the liquid carrier rocket. Its main function is to complete the connection between the ground gas supply system, the filling system and the rocket system, and can complete the filling and After the gas supply and other work, according to the established process, manual detachment, remote control detachment and even passive detachment as the rocket takes off. All the pipes for filling, discharging and controlling gas on the rocket form a circuit with the ground system through different forms of connectors. Therefore, the falling off of the connector is one of the most important actions in the rocket launch process. It will lead to ...
