Jet Engines :: physics jet jets engine engines

The BasicsA green locomotive locomotive cigarette be divided into several distinct sections intake, compressor, diffuser, flame chamber, turbine, and exhaust. These sections are much(prenominal)(prenominal) like the different cycles in a four-stroke reciprocating engine intake, compression, power and exhaust. In a four-stroke engine a fuel/ air power mixture is is brought into the engine (intake), matted (compression), and finally ignited and pushed out the exhaust (power and exhaust). In its nearly basic form, a cat valium engine works in much the same way. * Air comes in the front of the engine where it enters the compressor. The air is compressed by a series of small spinning blades aptly named compressor blades and leaves at a advanced pressure. The pressure ratio between the beginning and remnant of the compressor can be as much as 481, besides almost always 121 or more. * The air this instant enters the diffuser, which is nothing more than an area w here the air can expand and discredit its velocity, 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 located aft of the combustion chamber. At least some of these turbine blades are connected by a ray of light to the compressor blades to drive them. Depending on the type of engine, there 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 leave 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 airplane forward.The types of jet engines include * fanjet * Turbofan * Turboprop * Turbo shaf tTurbojetThe turbojet is the simplest of them all, it is just as described in The basics section. This style was the first type of jet engine to be used in aircraft. It is a pretty lowbred style used mostly in early military jet fighters such as the F-86.
