Turbofan Jet Engine
Jet engines use a number of rows of fan blades to compress air which then enters a combustor where it is mixed with fuel (typically JP fuel) and then ignited. The burning of the fuel raises the temperature of the air which is then exhausted out of the engine creating thrust. A modern turbofan engine can operate at as high as 48% efficiency. 24
There are six sections to a Fan Jet engine:
Fan
Compressor
Combustor
Turbine
Mixer
Nozzle

Car insurance - what you should know?
As you know, every car owner is obliged to insure your car. The fee, which you need to bring in this respect, however, is dependent on many factors. First of all, a key criterion in this regard is the model and brand of the insured car. This is the value of the car depends on the amount of possible compensation. It is also important that in which he was made our car and how many kilometers is already on the meter. It is known that with the number of kilometers traveled risk of defects is increasing. Nevertheless, important in this regard is how old is the owner of the car, because the amount of insurance premium depends on the metric of the holder of the car.

Turbine Power Plant
A gas turbine compresses air and uses it to turn a turbine. It is essentially a Jet engine which directs it's output to a shaft. There are three stages to a turbine: 1) air is drawn through a compressor where the temperature rises due to compression, 2) fuel is added in the combuster, and 3) hot air is exhausted through turbines blades which rotate a shaft connected to the compressor.
A gas turbine is a rotary machine similar in principle to a steam turbine and it consists of three main components: a compressor, a combustion chamber, and a turbine. The air, after being compressed in the compressor, is heated by burning fuel in it. About ? of the heated air, combined with the products of combustion, expands in a turbine, producing work output that drives the compressor. The rest (about ?) is available as useful work output. 26
Gas Turbines are among the MOST efficient internal combustion engines. The General Electric 7HA and 9HA turbine electrical plants are rated at over 61% efficiency. 27
