Problems solved by technology

However, using liquid oxygen and kerosene as new propellants, the pressurized delivery system is very different from the current rocket, especially the gas-liquid phase change of the pressurized system, the low-temperature two-phase flow of the delivery system, engine precooling and related pipelines, There are major changes in the design of valves, etc., and the complexity of the sys

Embodiment 1

[0044] like Figure 1-5 As shown, the gas-oxygen-kerosene rocket engine pressurized delivery system provided in this embodiment includes an oxygen supply system, a fuel supply system and a blow-off system;

[0045] The oxygen supply system includes an oxygen storage tank valve assembly 30, a first stop valve 3, a first one-way valve 10 and a second one-way valve 11;

[0046] The oxygen storage tank valve assembly 30, the first stop valve 3 and the first one-way valve 10 are connected in sequence through pipelines, the second one-way valve 11 is connected with the blowing system, and the first one-way valve The outlet of the valve 10 and the outlet of the second one-way valve 11 are connected to the thrust chamber 29 through the same pipeline; such a design avoids blowing off nitrogen from entering the oxygen supply system;

[0047] The fuel supply system enters the thrust chamber 29 through a pipeline after being connected with the blowing system.

[0048] In an optional imp...

Embodiment 2

[0057] Embodiment 2 of the present invention provides a small rocket engine propellant supply system, including the gas-oxygen kerosene rocket engine pressurized delivery system described in Embodiment 1 above.

[0058] The small rocket engine propellant supply system provided by Embodiment 2 of the present invention is provided with the gas-oxygen kerosene rocket engine pressurized delivery system provided by Embodiment 1, so it has the advantages of the gas-oxygen kerosene rocket engine pressurized delivery system provided by Embodiment 1. All beneficial effects will not be repeated here.

[0059] In summary, gas-oxygen has the excellent characteristics of non-toxic, non-polluting, non-corrosive, and does not require low-temperature storage. Aiming at the small-scale characteristics of small rockets, a gas-oxygen kerosene pressurized delivery system solution is proposed, but there is almost no such solution in China. The research on the gas-oxygen kerosene propellant deliver...

Abstract

The invention relates to the field of rocket-engine propellant delivery systems, in particular to a gas-oxygen-kerosene rocket-engine pressurizing delivery system and a small-rocket-engine propellantsupplying system. The pressurizing delivery system comprises an oxygen supplying system, a fuel oil supplying system and a blowing-off system; the oxygen supplying system comprises an oxygen storage tank valve assembly, a first stop valve, a first one-way valve and a second one-way valve; the oxygen storage tank valve assembly, the first stop valve and the first one-way valve are sequentially communicated through a pipe, the second one-way valve is communicated with the blowing-off system, and an outlet of the first one-way valve and an outlet of the second one-way valve are connected with a thrust chamber through the same pipe; the fuel oil supplying system is connected with the blowing-off system to enter the thrust chamber through the pipe. The gas-oxygen-kerosene rocket-engine pressurizing delivery system in the technical scheme is compared with a liquid-oxygen-kerosene rocket propellant delivery system, complex design such as pressurization-system gas-liquid phase transition, delivery-system low-temperature two-phase flow and engine pre-cooling are not required to be considered, and the complex degree and the quality of the system structure are also greatly reduced.

Description

technical field [0001] The invention relates to the technical field of a rocket engine propellant supply system and delivery system, in particular to a gas-oxygen kerosene rocket engine pressurized delivery system and a small rocket engine propellant supply system. Background technique [0002] The rocket engine pressurization delivery system is to control the pressure of the air pillow in the rocket propellant tank, deliver the propellant to the engine pump or combustion chamber according to the specified pressure and flow rate, and connect the booster and delivery system of the propellant tank, engine and ground equipment synthesis. The delivery system can be divided into two categories: extrusion type and pump type according to the different supply methods of engine propellant. Since the object of this system is a small rocket engine with a small total impulse, the extrusion conveying system with simple system structure, mature technology and reliable operation is select...
