Jet engine with electric propulsion function

Abstract

The invention discloses a jet engine with an electric propulsion function, comprising a jet combustion chamber, a fuel oil or fuel agent nozzle in the jet combustion chamber and a fuel gas spray pipe connected with the jet combustion chamber. The jet engine is characterized by also comprising an electric propulsion part used for separating positive ions from fuel gas as well as accelerating and neutralizing the positive ions. By adopting the jet engine with the electric propulsion function, the fuel oil or the fuel agent is led into for combusting to act on the electric propulsion part, and the speed of the fuel gas can be improved to be over 2 times higher than the original speed, thus the thrust-weight ratio of the engine is greatly improved, which is beneficial to doing work.

Description

technical field [0001] The invention relates to a jet engine with electric propulsion, which belongs to the technical field of jet engines. Background technique [0002] Existing turbojets, turbofans, turboprops, propfans, turboshafts, ramjet engines and liquid rockets all rely on the high-temperature, high-pressure gas jets produced by the combustion of their jet combustion chambers to do work. and fuel combustion value, the injection velocity of the gas is not very high; although the injection velocity of the electric rocket is high, its thrust is too small and can only be used in the space environment; and the high temperature generated by the combustion of the jet combustion chamber of the above-mentioned engine 1. High-pressure gas is plasma, from which positive ions can be separated. If the positive ions are accelerated by an electric field, their speed will be greatly increased, which is very beneficial to work; now the main purpose of improving the performance of the...

Problems solved by technology

[0002] Existing turbojets, turbofans, turboprops, propfans, turboshafts, ramjet engines and liquid rockets all rely on the high-temperature, high-pressure gas jets produced by the combustion of their jet combustion chambers to do work. and fuel combustion value, the injection velocity of the gas is not very high; although the injection velocity of the electric rocket is high, its thrust is too small and can only be used in the space environment; and the high temperature generated by the combustion of the jet combustion chamber of the above-mentioned engine 1. High-pressure gas is plasma, from which positive ions can be separated. If the positive ions are accelerated by an electric field, their speed will be greatly increased, which is very beneficial to work; now the main purpose of improving the performance of the above-mentioned engine is It is to increase the compression ratio, use fuel with high combustion value or increase the utilization rate of fuel, but these two aspects of improvement are very difficult. Although China can currently manufacture military and civilian aircraft and liquid rockets, it is difficult for military aircraft engines to be independent. Among them, the Russian AL-31 engine used by the Su-27 fighter (including the AL-31FN engine of the J-10 and J-10S) can only be provided by Russia, and then assembled in China, obviously it can be manufactured for military use Aircraft engines are the embodiment of a country's national defense strength and technological level. If the above-mentioned electric propulsion method is used to improve the existing military and civilian aircraft engines and jet engines of liquid rockets, it will undoubtedly greatly increase the injection speed of gas and increase the thrust-to-weight ratio of the engine. It is a shortcut to improve and enhance its technology
