Liquid recoil type two-stage booster rocket body

Abstract

An embodiment of the invention discloses a liquid recoil type two-stage booster rocket body and belongs to the field of liquid recoil force based experimental detection aircrafts. The liquid recoil type two-stage booster rocket body comprises a main rocket body and at least one two-stage rocket body, wherein two-stage rocket bodies are detachably connected with the main rocket body, the main rocket body comprises a main liquid storage chamber, a main pressure chamber, a control chamber and a pressure hopping device, the pressure hopping device moves according to the pressure inside the main pressure chamber, the control chamber is located at the top of the main pressure chamber and is detachably connected with the main pressure chamber through the pressure hopping device, the main liquid storage chamber is located at the bottom of the main pressure chamber and is communicated with the main pressure chamber, and a main spraying opening is arranged at the bottom of the main liquid storage chamber. According to the liquid recoil type two-stage booster rocket body, the atmospheric pressure serves as a pushing source, the liquid recoil force serves as the pushing force, the propulsion structure is simplified, the weight of the rocket body is reduced, two-stage rocket bodies are added on the main rocket body, and the rising height of the rocket can be increased.

Description

technical field [0001] The invention relates to the field of experimental exploration aircraft based on liquid recoil force, in particular to a liquid recoil type two-stage booster rocket body. Background technique [0002] A modern rocket is an aircraft that obtains reaction force by jetting high-temperature and high-pressure gas at high speed, and uses the reaction force generated to propel it forward. It is mainly composed of rocket body, propulsion system and guidance system connected in sequence. Among them, the rocket body is an indispensable part of the rocket, on which each system of the rocket is installed, and a large amount of propellant is contained inside it. When the rocket fuel burns, the gas ejected from the tail of the rocket body has a large momentum. According to the law of conservation of momentum, the rocket obtains equal and opposite momentum, so continuous recoil occurs. With the consumption of propellant, the rocket's The mass gradually decreases, a...
