Embodiment Construction
[0044] In the following, the terms "inner" or "inner" and "outer" or "outer" refer to a position relative to the axis of rotation of the axial turbine engine.
[0045] figure 1 Represents a simplified form of an axial turbine engine. In this case it is a ducted fan turbojet. The turbojet 2 comprises a first level of compression known as a low-pressure compressor 4 , a second level of compression known as a high-pressure compressor 6 , a combustion chamber 8 and one or more levels of turbines 10 . In operation, the mechanical power of the turbine 10 transmitted via the transmission shaft 11 to the rotor 12 causes the two compressors 4 to operate. The latter comprises rows of rotor blades associated with rows of stator blades. Thus, the rotation of the rotor about its axis of rotation 14 allows an airflow to be generated and progressively compressed up to the inlet of the combustion chamber 8 . A multiplier increases the rotational speed delivered to the compressor.
