Problems solved by technology

However, in China, the monitoring of the bending moment at the root of the launch vehicle is rarely involved. The common detachable plug connection cable is not suitable for this monitoring system. The reasons are as follows: (1) It is not easy to install on the support column of the launch pad. (2) The plug must fly with the rocket, and the volume and mass of the unplugged plug are large, so it brings additional mass, which greatly changes the state of the rocket; (3) It needs to occupy the range launch system control channel

Abstract

The invention relates to a cable disengaging device for a rocket root bending moment monitoring system, and further relates to a ground breaking test device of the cable disengaging device. The cabledisengaging device satisfies the real-time monitoring requirement for the root bending moment before a rocket takes off, does not affect the safe take-off of the rocket, adapts to the shooting range process, is reliable in operation, and is easy to pull apart. The ground breaking test device of the cable disengaging device is used for verifying the disengaging effectiveness and safety of the cabledisengaging device.

Description

technical field [0001] The invention relates to a cable release device of a rocket root bending moment monitoring system, and further relates to a ground breaking test device of the cable release device. Background technique [0002] In order to obtain the wind load of the rocket body under the action of the shallow wind in the shooting range, and to verify the effect of the wind load design and the wind-proof and load-reducing structure, the transition process of the launch vehicle from the technical area of ​​the shooting range to the launch area and the launch of the rocket in the launch area after filling From the tower to the state before launch, the rocket root bending moment monitoring system is often used to monitor the rocket root bending moment load. According to the requirements of the launch vehicle and the shooting range, the monitoring method needs to be simple and optimized, and the impact on the measurement, launch and control system of the shooting range sho...
