Liquid gas afterburner jet engine and method for realizing afterburning flying of jet plane

Abstract

The invention provides a liquid gas afterburner jet engine and a method for realizing afterburning flying of a jet plane. The jet engine comprises an air incoming way, a gas compressor, burning chambers with fuel nozzles, a turbine, an afterburner, a tail nozzle and liquid gas nozzles extending into the afterburner. By the method, the jet engine can be ensured to fully utilize thermal expansion of liquid gas to do work during afterburning propelling, and thrust of the jet engine is increased more efficiently, so that burning efficiency of the jet engine is improved obviously, thrust is increased, power cost is lowered, environmental pollution is reduced, and probability of being attacked by an infrared weapon can be lowered.

Description

technical field [0001] The invention relates to a liquid gas afterburner jet engine and a method for realizing afterburner flight of a jet aircraft. Background technique [0002] The engines used in modern high-performance aircraft are usually turbojet or turbofan engines. These two engines are equipped with an afterburner, which is mainly composed of a fan, an air compression chamber, a combustion chamber, a turbine, and an afterburner. The afterburner is composed of a diffuser, an igniter, a nozzle, a flame Stabilizers, anti-vibration heat shields and cylinders, etc., are used to inject fuel into the gas delivered or air delivered through the external duct and ignite and burn when the aircraft engine is working with power, so as to increase the temperature of the airflow , so that the engine thrust can be increased in a short time. [0003] When the aircraft is flying without afterburner, its engine sucks air through the fan and introduces it into the air compression cha...

Problems solved by technology

Although these technologies have the advantages of increasing the power of the aircraft engine and improving the climb and high-altitude maneuverability of the aircraft, they also show obvious disadvantages. In the case of the same heat, it will cause defects such as low temperature rise and less vaporized gas due to high critical temperature and high boiling point; the fuel injection type and the mixture of fuel and water injection will cause problems such as fuel waste, high cost and serious pollution.
