Embodiment Construction
[0037] In the following description, the terms inner or outer refer to a position relative to the axis of rotation of the axial turbine.
[0038] figure 1 A schematic representation of an axial turbine. In this case, it is a double-flow turbojet. The turbojet engine 2 comprises a first compression stage, a so-called low-pressure compressor 4 ; a second compression stage, a so-called high-pressure compressor 6 ; a combustion chamber 8 ; and one or more turbine stages 10 . In operation, the mechanical power of the turbine 10 is transmitted via the central shaft to the rotor 12 and drives the two compressors 4 and 6 . The speed change mechanism increases the rotational speed delivered to the compressor. Alternatively, different turbine stages can each be coupled to a compressor stage via respective concentric shafts. A compressor stage includes several rows of rotor blades associated with rows of stator blades. The rotation of the rotor about its axis of rotation 14 generate...
