Embodiment Construction
[0053] In the following description, the terms inner or inner and outer or outer relate to a position relative to the axis of rotation of the axial turbine engine. The axial direction corresponds to a direction along the axis of rotation of the turbine engine. Upstream and downstream are referred to with reference to the main flow direction of the flow in the turbine engine.
[0054] figure 1 An axial turbine engine is shown in a simplified manner. In this precise case, it's the ducted fan turbine engine used to power the aircraft. The turbojet engine 2 comprises a first compression stage called a low-pressure compressor 4 , a second compression stage called a high-pressure compressor 6 , a combustion chamber 8 and a one- or multi-stage turbine 10 . In operation, the mechanical power of the turbine 10 , transmitted via the central shaft to the rotor 12 , moves the two compressors 4 and 6 . The latter includes rows of rotor blades associated with rows of stator blades. The...
