Jet engines have now been successful as aircraft motors for almost a century in this article we will explain logically the technology behind jet engines, step by step jet engines can make airplanes move forward using a very simple principle, just like the principle of making a balloon full of air. moving perfectly, the third law of grace news tone, just as the reaction force produced by the air moving the balloon, which makes the plane move forward is the reaction force generated by the high-speed jet in the tail of the jet engine.
So the work of a jet engine is about producing high-speed jets the higher the speed of the jet the greater the thrust, that thrust is what makes the plane move forward, this high-speed exhaust is obtained by combining several techniques, if you can heat the incoming air to a high temperature then the air will expand fantastically and will create a high speed jet.
It is for this purpose that a combustion chamber is used, a form of fuel atomization is burned in the combustion chamber, effective combustion requires the air to be at a sufficiently high temperature and pressure, to bring the air into this condition a series of compressor stages are used, a rotating compressor vane adds energy into the liquid and then its temperature and pressure rise to a level suitable for maintaining combustion.
The compressor receives energy to rotate from the turbine which is placed right after the combustion chamber, the compressor and turbine are attached to equal portions, the high energy fluid leaving the combustion chamber makes the turbine blades spin, as you can see the turbine blades have a special air foil shape which creates lift and makes it spin.
The pressure also decreases as the turbine absorbs energy from the liquid, our goal is achieved through these steps the really hot and high speed air emitted from the engine output the engine cover chamber becomes narrower towards the outlet which then results in an even greater jet speed, in short operation Synchronized combustion chamber compressors and turbines allow the aircraft to move forward.
Modern aircraft use a slightly improved turbine compressor arrangement and are called two tens, two independent turbine compressor stages are used in this section, the outer turbine compressor shaft passes through the interior concentrically, the outer turbine is made into a low energy fluid object and will run at a faster speed. lower than the turbine in the lower cross section of the lower-velocity vane this lower speed helps reduce the centrifugal pressure induced at the base thereby increasing the resistance of the propeller.
Some modern aircraft even use three ten engines, the engines we have discussed so far are more specifically referred to as turbojet engines. Turbojet engines tend to produce high noise levels, revolutionary improvements were made to these engines by installing a large fan which has a low pressure ten, the engine this type is called a turbofan engine and almost every commercial aircraft uses this engine.
Turbofan engines pass a large amount of air, the constriction that occurs as they pass through these ducts provides a good jet speed for the air that is passed, most of the thrust in turbofan engines comes from event reaction forces, in fact the fans greatly increase the airflow in the system by sucking in more air. .
Thus the van helps increase thrust so this means that the engine creates high thrust with less fuel cost this is the reason why turbofan engines are very fuel efficient the noise produced by jet engines is highly dependent on the jet output speed as in turbofan engines the air The cold that is passed mixes with the hot air so that it can keep the athlete's speed within a certain limit.
Thus it can overcome the noise problem that occurs, with a quieter exhaust and better fuel economy turbofan engines will continue to dominate aircraft proportioning systems, we hope this video can provide a good introduction to the workings of jet engines, please support we are at patriot dot com so that we can publish all our English videos into Indonesian, thank you.
