Abstract

The invention provides an airflow heat insulation airspace ramjet comprising an air inlet passage (diffuser), an ignition device, a combustion chamber and a propelling nozzle. The airflow heat insulation airspace ramjet is characterized in that the propelling nozzle is composed of a shell (2) and an inner pipe (4), an air chamber (C) is formed between the shell (2) and the inner pipe (4), and an air inlet is arranged in the A-section of the inner pipe (4); when an aircraft flies, kinetic energy is converted into pressure energy in the process that head-on airflow passes through the air inlet passage, compressed air enters the combustion chamber to be mixed with fuel for constant-pressure combustion, and generated high-temperature combustion gas swells and accelerates in the inner pipe (4) prior to being discharged so as to generate thrust. The original advantages of the ramjet are retained, and meanwhile energy conservation and efficiency improvement are achieved.

Description

technical field [0001] The invention belongs to a ram jet engine. Background technique [0002] The ramjet engine (ramjet for short) used in missiles and spaceflight is an air jet engine that has a very simple structure, can send out a large thrust, and is suitable for high-altitude and high-speed flight. The ramjet engine is a kind of air jet engine that uses the oncoming airflow to enter the engine and then decelerates to increase the static pressure of the air. It usually consists of three parts: the intake port (also known as the diffuser), the combustion chamber, and the propulsion nozzle. The ramjet engine does not have a compressor (it does not need a gas turbine), so it is also called an air jet engine without a compressor. The ramjet is mainly an aeroengine that uses high-speed oncoming airflow to enter the engine and decelerates the air to pressurize it. Usually by the inlet (also known as diffuser), combustion chamber and nozzle composition. When the aircraft ...
