Abstract

The embodiment of the application provides a pneumatic combination valve of a rocket engine, the rocket engine and a carrier rocket. The pneumatic combination valve of the rocket engine comprises a valve cover, a valve body, a first moving assembly and a second moving assembly. The valve cover and the valve body enclose to form a cavity. The cavity accommodates the first portion of the first moving assembly and the first portion of the second moving assembly. The valve body comprises a first valve body part and a second valve body part. The first valve body part is provided with a first channel, and the first moving assembly passes through the first channel. The second valve body is provided with a second channel, and the second moving assembly passes through the second channel. The firstmoving assembly and the second moving assembly are used for respectively stopping the first channel and the second channel. The first moving assembly is used for driving the second moving assembly tomove, so that the first channel and the second channel communicate with each other. According to the pneumatic combination valve of the rocket engine, the rocket engine and the carrier rocket, the fuel and the oxidant can be controlled to enter a fuel gas generator for combustion through the pneumatic combination valve, so that the lightweight design and the simplification of the structure of thecarrier rocket are facilitated.

Description

technical field [0001] The present application relates to the field of launch vehicle technology, in particular, the present application relates to a pneumatic combination valve of a rocket engine, a rocket engine and a launch vehicle. Background technique [0002] In recent years, my country's aerospace industry has developed rapidly, and various technologies involved in rocket-related fields have achieved rapid progress. The main power source of aerospace equipment is the rocket, and the rocket engine is the core device of the rocket, and it is a component with high technical content. The rocket engine uses the principle of impulse, has its own propellant, and does not rely on the outside air to turn the propellant in the propellant tank or vehicle into a high-speed jet, which generates thrust due to Newton's third law of motion. [0003] However, in existing rocket engines, the number of pneumatic valves is large, making the control of the pneumatic valves complicated, m...
