Description
Technical Field
The utility model relates to a rocket launch field, concretely relates to prevent wind deloading device on large-scale carrier rocket launch pad.
Background
When the rocket is in a vertical transition, if the wind power is large, the structural strength of the rocket is greatly tested. Wind is the movement of air in the atmosphere, and if the wind meets the obstruction of the structure, the surface of the structure generates wind pressure, and the larger the air flow speed is, the larger the wind pressure is, so that the structure generates large deformation and vibration. The rocket is also influenced by bottom wind in the vertical transfer process or when the rocket is erected in a launching site, and a main external interference source of the structure is formed.
Generally speaking, the wind speed of the inland launching site has little change along with the height, and the launch of the rocket is not greatly influenced. However, in some coastal areas, a launching site is affected by strong tropical storms and typhoons, and due to the fact that the wind speed is higher and higher along with the increase of the height of the launching site, the speed of the launching site which is five sixty meters away from the ground is far higher than the wind speed of the ground, namely the speed of the launching site is slightly higher than the wind speed of the ground, people on the ground can feel breeze, the high wind speed can be converted into strong wind at the first-level height of the rocket, the difficulty is increased for the vertical transition of the rocket, and therefore wind prevention measures are necessary to protect.
