How to jet engine work?

jet Engines have been the successful drivers of aircrafts for nearly a century now in Jet Engine we will explain the technology behind the jet Engine in a logical step by step manner a jet Engine keeps an aircraft moving forward using a very simple principle The some that make an air filled balloon move. yes, newton third law of motion just like the reaction force produceds by the air moves the ballqon.The reaction force produceds by the high speed jet at the tail of the jet Engine makes it movies forward. so the working of jet Engine is all about producing a high speed jet at the exit the higher the speed of the jet the greater the thrust force. The thrust force makes an aircraft move forward such high speed exhaust is achieved by a combination of techniques. If you can heat the incoming color air and hot air to a high temperature it will expand tremendously and will created the high velocity jet. For this purpose a combustion chamber is used {fuel injecttion holes} and {air- entry holes}. An atomized form of the fuel is burnt in the combustion chambers-Fuel injecttion holes and air entry holes. Effective combustion requires air to be at moderately high temperature and pressure. To bring the air to this condition a set of compressor stages are used. The rotating blades of the compressor add energy to the fluid and its temperature and pressure rise to a level suitable to sustain combustion. The compressor receives the energy for the rotation from a turbine which is placed right after the combustion chamber? The compressor and turbine are attached to the some shaft- STATOR BLADE and ROTOR BLADE.The High energy fluid that leaves the chamber makes the turbine blades turn" You can see that the turbine blades have a special airfoil shape which created lift force and makes them turn - flite airfoil. As the turbine absorbs energy from the fluid its pressure drops= 1600c, = 35 bar =350c, = 0.75 bar. Through these steps we have achieved our objective a really hot and high speed air emitted from the exit of the Engine- = 10c, = 350c. The Engine case becomes narrower towards the outlet which results in even greater jet velocity-(Narrow outlet). in short the synchronized na operation of the compressor combustion chamber and turbine makes the aircraft move forward. Modern aircraft used a slightly improved compressor turbine arrangement called a 2 (two) spool. Here 2 (two) independent turbine compressor stages are used. The shaft of the outer compressor turbine passes concentric (Li) through the inner 1 (one)-Low pressure spool and high pressure spool. The outer turbine is subjected to a low energy fluid and will run at a lower speed than the inner turbine. (N1 and N2) N1>N2. Low pressure blades are longer this (low speed) helps to reduct centrifugal stress induced at the root thus improved the blades (Life) N1>N2. Some modern aircraft even use a 3 (three) spool engine. The engine we have discussed so far is more specifically called as turbo jet engine. Turbo jet engine tend to produce high levels of noise (A). Revolutionary improvement was made to this engine by fitting a large fan with the low pressure spool. Such engines are called Turbofan engine and almost every commercial aircraft run on them a Turbofan engine bypass is a huge amount of air. The ever narrowing bypass duct provides a good jet velocity to the bypass air. in a turbofan engine the majority of the thrust force comes from the fans reaction force. Further the fan greatly improves airflow in the systems By sucking in more air. Thus it help to improved the thrust. This means high thrust creation with a expand of slightly more fuel. This is the reason why turbofan engine are highly fuel economical. The noise produced By a jet engine is highly Dependent on the exit jet velocity. Since in a turbofan the bypass cold air gets Mixed with the hot air it is possible to keeps the outlet velocity within a limit. Thus it overcomes the noise problem. With quieter exhaust and better fuel economy the turbofan engine continued to dominate aircraft propulsion systems. We hope this provides a nice introduction to the working of jet engine
