Problems solved by technology

[0003] At present, there are no 0-second shedding and venting connector products for domestic active launch vehicles. The latest domestic launch vehicle has only achieved 0-second detachment of the hydrogen emergency exhaust connector, while the propellant and venting connectors are all 0 seconds. seconds before ignition

Abstract

The invention relates to a zero-second dropping-off normal-temperature propellant adding and discharging connector for a carrier rocket and a method. The zero-second dropping-off normal-temperature propellant adding and discharging connector for the carrier rocket comprises a connector ground part, a connector on-rocket part, a first pulley set, a second pulley set, a third pulley set, a recoveryrope, a traction rope, a counterweight, an air cylinder and a ball lock; the connector on-rocket part is mounted on a propellant storage tank of the carrier rocket, the second pulley set and the air cylinder are mounted on a launching tower, the connector ground part is connected with the connector on-rocket part through the ball lock, the counterweight is connected with the connector ground partthrough the second pulley set and the recovery rope, and the air cylinder is connected with the ball lock through the third pulley set, the traction rope and the first pulley set. The connector between a ground normal-temperature propellant filling pipeline and the on-rocket propellant storage tank can drop off reliably after zero-second ignition for taking off of the carrier rocket.

Description

technical field [0001] The invention relates to a connector between a propellant filling pipeline on the ground at normal temperature and a propellant storage tank on an arrow, in particular to a propellant filling and draining connector at normal temperature which can reliably fall off after a carrier rocket is ignited and taken off within 0 seconds. Background technique [0002] With the development of launch vehicle technology, in order to improve the safety of operators, after the propellant filling is started, the launch site will enter an unattended state until the rocket is successfully ignited and taken off, or the rocket fails and the propellant is released. The unattended technology of the connector between the ground filling pipeline and the propellant tank on the arrow has become one of the key technologies, and the 0-second drop-off connector is the key to realize this key technology. One of the main ways, that is: after the propellant filling of the tank is com...
