This video clip shows and animated cutout of the Honeywell T55-L714A turboshaft engine. The blue section is the compressor and N1/NG section. This section is responsible for compressing the air needed for combustion and engine cooling. Only 20% of the air is used for combustion, the other 80% is for engine cooling. The red section is comprised of two N2/NP turbine sections that turn using the escaping heat and air from fuel combustion. These two sections can generate over 5,000 shp. That power is transferred through a shaft running back through the front of the engine to the engine transmission.

This is a picture of the fuel nozzles that supply fuel in a specific jet pattern. They are connected with 14 nozzles per fuel rail for a total of 28 jets. They receive fuel at approximately 750 psi. This high pressure helps with heating the fuel and atomization. Average fuel consumption is around 1200 pounds per hour (pph) for each engine. With jet fuel weighing 6.7 pounds per gallon, that makes an average fuel burn of 358 gallons per hour (gph).
