<onlyinclude>A '''gas turbine''' is a type of [[turbine]] that uses [[pressure|pressurized gas]] to spin it in order to [[electrical generation|generate electricity]] or provide [[kinetic energy]] to an airplane or jet.</onlyinclude> The process to do so is called the [[Brayton cycle]]. In all modern gas turbines, the pressurized gas is created by the burning of a [[fuel]] like [[natural gas]], [[kerosene]], [[propane]] or jet fuel. The [[heat]] generated by this fuel expands [[air]] which flows through the turbine to supply useful [[energy]].<ref name=hsw>Brain, Marshall. "How Gas Turbine Engines Work" 01 April 2000. HowStuffWorks.com. [Online], Available: <http://science.howstuffworks.com/transport/flight/modern/turbine.htm> 28 May 2015.</ref>

==Operation==

Gas turbines are theoretically simple, and have three main parts as seen in Figure 2:<ref name=hsw/>

#'''Compressor'''- Takes in air from outside of the turbine and increases its pressure.
#'''Combustor'''- [[Combustion|Burns the fuel]] and produces high pressure and high [[velocity]] gas.
#'''Turbine'''- Extracts the energy from the gas coming from the combustor.

====Compressor====
In Figure 2, air is sucked in from the left and input to the compressor which consists of many rows of fan blades. In some turbines, the pressure of the air can increase by a factor of 30.<Ref name=hsw/>

====Combustor====
The high pressure air flows into this area, which is where the fuel is introduced. The fuel gets injected constantly into this part in order for the energy through the turbine to be constant.

====Turbine====
The turbine is connected to the compressor blades by a shaft, and they spin separately. The compressor connects to the turbine which is connected to an output shaft, and because the turbine spins separately, it can get up to tremendous speeds due to the hot gas flowing through it. This final shaft generates ''enormous'' amounts of [[horsepower]], with large airplane turbines generating nearly 110000 hp - twice the power generated by the Titanic.<ref>The Atlantic, ''A Single Boeing 777 Engine Delivers Twice the Horsepower of All the Titanic's'' [Online], Available: http://www.theatlantic.com/technology/archive/2011/12/a-single-boeing-777-engine-delivers-twice-the-horsepower-of-all-the-titanics/250698/</ref>
