Gas pressure balancing device used for carrier rocket and carrier rocket

Abstract

The invention relates to the technical field of carriers, and provides a gas pressure balancing device used for a carrier rocket and the carrier rocket. A pressure relief bolt of the gas pressure balancing device is used for cooperating with a gas leakage hole preset in a rocket body of the carrier rocket, and therefore the gas pressure balancing device has the condition that gas pressure inside the rock body communicates with gas pressure outside the rocket body. Preset elastic pre-tightening force is applied to a windproof cover plate by utilizing a springback assembly, and therefore selective sealing to a first gas channel is realized. Before the carrier rocket takes off, the windproof cover plate seals a first sealing channel, and the situation that redundant objects are introduced into the rocket body when the rocket in the final assembly and transportation environment can be effectively avoided. Dynamic balancing of atmospheric pressure inside and outside the rocket body can be realized by taking the stressed boundary condition of the windproof cover plate in the flying process of the rocket as the constraint condition of the springback assembly. Airtightness of the gas leakage hole is structurally guaranteed, and the gas leakage hole does not need to be blocked manually. Before launching, a plugging object of the gas leakage hole does not need to be dismounted, and potential safety hazards brought by toxic propellant filling of the rocket are avoided.

Description

technical field [0001] The present application relates to the field of vehicle technology, and in particular, the present application relates to an air pressure balance device for a launch vehicle and the launch vehicle. Background technique [0002] The earth has undergone hundreds of millions of years of evolution. Under the action of multiple factors such as the earth's gravity, a large amount of gas has gathered around the earth, forming the current thick atmosphere. In 1654, the famous "Ma Debao Hemisphere" experiment made people realize the existence of atmospheric pressure. With the further development of science and technology, human beings have a deeper understanding and research on atmospheric pressure. [0003] The mission of the launch vehicle is to fly off the surface of the earth and send the payload into the predetermined orbit. In the process of leaving the earth, the rocket's box, shell and other structures bear the pressure brought by the pressure differe...
