Problems solved by technology

[0005] However, the saturated vapor pressure of nitrous oxide varies greatly with temperature, and temperature fluctuations will cause a large change in boost pressure. With the gasification output of nitrous oxide, the temperature decreases, and the pressure provided continues to decrease, which is not suitable for the stable operation of rocket engines.

Abstract

The invention relates to the technical field of rocket pressurization propulsion systems, in particular to a nitrous oxide temperature control pressurization system. The nitrous oxide temperature control pressurization system comprises a propellant storage box, a nitrous oxide storage box, nitrous oxide, an evaporator, a heater, a valve, a pipeline, an intelligent pressure adjuster, a pressure sensor and a temperature sensor; the nitrous oxide, the evaporator and the heater are all arranged in the nitrous oxide storage box; the propellant storage box communicates with the nitrous oxide storagebox through the pipeline; the valve is arranged on the pipeline; the intelligent pressure adjuster is connected with the heater, the evaporator and the valve and arranged outside the nitrous oxide storage box; the temperature sensor is arranged in the nitrous oxide storage box; the pressure sensor is arranged in the propellant storage box; and the intelligent pressure adjuster is in signal connection with the pressure sensor, the temperature sensor, the heater, the evaporator and the valve. According to the nitrous oxide temperature control pressurization system, the pressure of the propellant storage box can be adjusted, stable pressurized gas is provided, and moreover variable pressure of the pressurized gas is achieved.

Description

technical field [0001] The invention relates to the technical field of rocket booster propulsion systems, in particular to a nitrous oxide temperature-controlled booster system. Background technique [0002] The extruded pressurized delivery system consists of a propellant tank, a pressurized system and a pipeline delivery system. Cylinder-type gas pressurization system is a commonly used pressurization system. For solid-liquid mixed rocket engines that work for a long time, the pressure in the bottle is as high as 30MPa or even higher; Liquefied and stored in a low-pressure liquid state. [0003] Nitrous oxide (N 2 O) It has the characteristics of high saturated vapor pressure, about 5MPa at normal temperature, and its pressure changes approximately linearly with temperature, which can be used as pressurized gas for extrusion pressurization system; it is also non-toxic, non-corrosive and stable at normal temperature Good stability and other advantages. [0004] Compared...
