Jet Engines :: physics jet jets engine engines

The BasicsA jet locomotive engine can be divided into several diaphanous sections intake, compressor, diffuser, combustion chamber, turbine, and exhaust. These sections are often like the different cycles in a four-stroke reciprocating engine intake, compression, power and exhaust. In a four-stroke engine a give the sack/ bare mixture is is brought into the engine (intake), compressed (compression), and finally ignited and pushed bring out the exhaust (power and exhaust). In its most basic form, a jet engine works in much the same way. * Air comes in the see of the engine where it enters the compressor. The air is compressed by a series of scummy spinning blades aptly named compressor blades and leaves at a high pressure. The pressure dimension between the beginning and polish off of the compressor can be as much as 481, but almost always 121 or more. * The air now enters the diffuser, which is nothing more than an area where the air can expand and lower its v elocity, thus increasing its pressure a little bit more. * The high pressure air at the end of the diffuser now enters the combustion chamber where it is mixed with fuel, ignited and burned. * When the fuel/air mixture burns, the temperature increases (obviously) which makes the air expand. * This expanding gas drives a set of turbine blades dictated aft of the combustion chamber. At least some of these turbine blades are committed by a shaft to the compressor blades to drive them. Depending on the type of engine, on that point may be another(prenominal) set of turbine blades used to drive another shaft to do other things, such as turn a propeller or generator. * The left over energy not extracted by the turbine blades is pushed out the back of the engine (exhaust section) and creates thrust, usually used to drive an planer forward.The types of jet engines include * turbojet engine * Turbofan * Turboprop * Turbo shaftTurbojetThe turbojet is the simples t of them all, it is just as described in The basics section. This drift was the first type of jet engine to be used in aircraft. It is a pretty primitive style used mostly in early military jet fighters such as the F-86.
