Please give me abstract & working for mini jet engine

A jet engine is a reaction engine that discharges a jet of rapid motion that generates thrust by jet propulsion. This broad definition includes air jet engines (turbojets, turbojets, jet jets, and jet jets) and airless jet engines (such as rocket engines). In general, jet engines are combustion engines.In common parlance, the term "jet engine" refers to an internal combustion air jet engine. These typically feature a turbine-driven rotary air compressor, with surplus energy providing thrust via a propellant nozzle - this process is known as the Brayton thermodynamic cycle. Jet aircraft use these engines for long distance travel. Early jet aircraft used turbojet engines that were relatively ineffective for subsonic flight. Modern subsonic aircraft usually use more complex high-bypass turbofan engines. These engines offer high speed and higher fuel efficiency than propellers for pistons and propellers over long distances.

Working

Jet engines move the plane forward with a great force that is produced by a tremendous thrust and causes the plane to fly very fast.All jet engines, which are also called gas turbines, work on the same principle. The engine sucks the air in the front with a fan. A compressor increases the air pressure. The compressor is made with many blades attached to a shaft. The blades spin at high speed and compress or compress the air. The compressed air is then sprayed with fuel and an electric spark ignites the mixture. The combustion gases expand and blow through the nozzle, at the back of the engine. As the gas jets recede, the engine and plane are pushed forward. As the hot air goes to the nozzle, it passes through another group of blades called the turbine. The turbine is attached to the same axis as the compressor. Turning the turbine causes the compressor to rotate.

The image below shows how air flows through the engine. The air passes through the motor core as well as around the core. This makes some of the air very hot and some are colder. The cooler air is mixed with the hot air in the engine outlet area.
