Turbojet engine

Turbojet engines, the first jet engine generation, are single-flow engines which means that the total volume of air ingested flows through the compressor, the combustion chamber and the turbine. The thrust is then produced by the exhaust gases exiting the engine at high velocities. Because of the low efficiency and the high noise levels turbojet engines are no longer produced today.
