The Turbojet with Afterburners

· For aircraft that require higher speeds and quick acceleration, the typical turbojet is augmented with afterburners after the last turbine.

· When aircraft reach speeds near mach, they experience a sharp increase in drag. To overcome this excess drag, fuel is dumped into the exhaust flow and ignited providing the excess thrust.

· This method of propulsion is not fuel efficient at all, since a steady stream of fuel is dumped in rings and ignited. Because of this fact, the afterburners cannot be ran for the entire flight, otherwise the aircraft’s range would be greatly decreased.
