Thrust for take-off

How does a modern gas turbine engine work?

Today's gas turbine engines are turbofan, or bypass, engines.

The air the engine needs for combustion is ingested by a fan up front. The low-pressure and high-pressure compressors compress the air and force it into the combustor. Here fuel is injected and mixed with the inflowing compressed air, and the fuel-air mixture continuously burned. The resultant heat expands the gas to a multiple of its volume, causing it to escape from the combustor in a high-energy stream. The gas rushes through the high-pressure and low-pressure turbines, causing them to rotate and producing the energy needed to drive the compressor and fan. A major portion of the thrust powering the aircraft is produced by the fan.
