Abstract

The invention provides a fall-off hold-down system for a carrier rocket and an injection connector. The fall-off hold-down system for the carrier rocket and the injection connector comprises an activerecovery unit and a passive hold-down unit, wherein the active recovery unit is used for actively withdrawing the injection connector and a pipeline thereof when the rocker takes off within 0 secondso that the injection connector and the pipeline thereof fall off from a rocket body or are far away from the rocket body; the active recovery unit is also used for pulling the injection connector andthe pipeline thereof; and the passive hold-down unit is used for pulling the injection connector and the pipeline thereof to prevent the injection connector and the pipeline thereof from overhangingor freely falling. According to the fall-off hold-down system for the carrier rocket and the injection connector, by arranging the active recovery unit and the passive hold-down unit, the injection connector and the pipeline thereof are pulled down from the rocket body or are pulled away from the rocket body first, and then the injection connector and the pipeline thereof are pulled to be locked at a preset height. The fall-off hold-down system for the carrier rocket and the injection connector can prevent the injection connector and the pipeline thereof from overhanging or freely falling whenthe rocket takes off within 0 second so that the rocket launching safety and reliability are enhanced.

Description

technical field [0001] The application belongs to the technical field of launch vehicles, and in particular relates to a fall-off containment system for a filling connector of a launch vehicle. Background technique [0002] A filling connector is provided on the launch vehicle, for example, a ground propellant storage device can fill the rocket body with fuel through the filling connector. In some launch scenarios, minutes before the rocket takes off, the rocket body is parked vertically on the launch pad, and all restrictions are lifted. The vertical arm and the filling main pipe are opened to a preset avoidance angle, and the filling connector is connected to the rocket body with the help of the restraining rope to complete the fuel replenishment before the rocket launch. [0003] In the existing technology, when the rocket receives the take-off command from the ground control center and takes off in 0 seconds, the filling connector is prone to hang or free fall, which wi...
