Definitions
- German patent DE 906 975 proposes a wheel whose sail is more advanced in the axial direction at the periphery than at an intermediate diameter of the impeller.
- FIG. 3 is a longitudinal section of a centrifugal compressor according to a first embodiment of the invention.
- FIG. 1 A turbomachine, more specifically in the form of a turbine engine 1, is illustrated schematically for explanatory purposes in FIG. 1.
- This turbine engine 1 comprises, in the direction of flow of a working fluid, an axial compressor 2, a centrifugal compressor 3, a combustion chamber 4, a first axial turbine 5, and a second axial turbine 6.
- the turbine engine 1 also comprises a first rotary shaft 7 and a second rotary shaft 8 coaxial with the first rotary shaft 7.
- the rotary shafts 7 and 8 rotate at speeds of the order of 5000 to 60000 revolutions per minute.
- the rotating parts of the compressors 2. and 3 and the turbines 5 and 6 are therefore subjected to great efforts by the centrifugal forces.
- FIG 2 one can appreciate how these centrifugal forces act on the wheel 101 of a conventional centrifugal compressor known to those skilled in the art.
- This wheel 101 has a sail 102 substantially axisymmetric and having a front face 103 and a rear face 104.
- the blades 105 are fixed by the blade roots 115 on the front face 103 of the sail 102.
- the blades 205 are fixed by the blade roots 215 on the front face 203 of the 202 and each also have a blade head 216 opposite to the blade root 215, a leading edge 206 with a substantially radial orientation and a trailing edge 207 with a substantially axial orientation, located radially outwardly and axially behind the leading edge 206.
- the compressor 3 comprises a conventional radial diffuser 212 with straightening vanes 213.
