Abstract
The embodiment of the invention discloses a liquid backflushing single-stage rocket body and belongs to the field of experiment detection planet aircrafts on the basis of a liquid recoil force. The liquid backflushing single-stage rocket body comprises a liquid storage cabin, an air pressure cabin, a control cabin and a pressure jump device for actuating according to the pressure in the air pressure cabin; the control cabin is positioned at the top of the air pressure cabin; the control cabin is separably connected with the air pressure cabin by the pressure jump device; the liquid storage cabin is positioned at the bottom of the air pressure cabin and is communicated; and the liquid storage cabin is provided with a jet orifice. According to the liquid backflushing single-stage rocket body provided by the embodiment of the invention, the air pressure is used as a push source and the liquid recoil is used as a pushing force; a propelling structure is simplified; and the weight of the rocket body is reduced. Moreover, a propellant can be liquid which is low in cost and is difficult to burn, and thus, operation cost can be greatly reduced and safety is improved.
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 single-stage 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 propellant in the rocket 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 mass of the rocket decreases gr...
