Embodiment Construction

[0032] Combine below figure 1 and figure 2 , the present invention is further described:

[0033] Such as figure 1 Shown, a kind of ramjet engine comprises intake duct 14, combustion chamber 5 and exhaust pipe, and air diversion structure is arranged at the inlet end of intake duct 14, and air diversion structure comprises high-pressure air input pipe 2, high-pressure air cavity 3 and The nozzle 1 and the high-pressure air chamber 3 are connected to the air inlet 14, and the high-pressure air in the high-pressure air input pipe 2 enters the high-pressure air chamber 3 and enters the air inlet 14 through the nozzle to realize the Coanda effect of hydrodynamics. The high-pressure air chamber 3 is an annular high-pressure air chamber, which is fixedly attached to the outer wall of the air inlet 14, and the nozzles are multiple and annularly distributed on the inner wall of the air inlet 14. The annular high-pressure air cavity can achieve better Coanda effect; the nozzle can ...

Abstract

The present invention relates to a ramjet engine comprising an air inlet channel (14), a combustion chamber (5) and a tail jetting tube, wherein an air drainage structure is arranged at the inlet end of the air inlet channel (14) and comprises a high-pressure air input pipe (2), high-pressure air cavities (3) and nozzles (1); the high-pressure air cavities (3) are connected onto the air inlet channel (14); the high-pressure air in the high-pressure air input pipe (2) enters the high-pressure air cavities (3) and enters the air inlet channel (14) through the nozzles, thereby implementing the effect of introducing a large amount of air. According to the ramjet engine, the air drainage structure is arranged in the air inlet channel; the high-pressure air generated by gasifying a small amount of liquid air is jetted and is used for driving the surrounding air to output a large amount of low-pressure airflow at one end at a high speed, so that the start of the ramjet engine under the static pressure is implemented; the operation stability of the ramjet engine of an aircraft using the engine in a stall condition is achieved.

Description

[0001] technical field [0002] The invention relates to a ramjet engine, in particular to a liquid air-assisted ramjet engine. [0003] Background technique [0004] 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 has no compressor (and does not need a gas turbine), so it is also called an air jet engine without a compressor. [0005] The ramjet is mainly an aeroengine that uses high-speed oncoming airflow to enter the engine and decelerates the air to pressurize it. It usually consists of an intake port, a combustion chamber and a nozzle. When the aircraft is flying, the head-on airflow converts kinetic energy into pressure during the process of passing through the intake port. The compressed air enters the c...
