Abstract (en)
[origin: EP1473438A2] The turbine has a high pressure body (2) including a single stage of wings (20) mounted on a shaft (21). The shaft is maintained by a bearing block (210), and is directly coupled to a shaft (40) of a speed-reduction gear (4). The wings have a profile with channels converging then diverging from an input towards an output. A ratio of pressure between the input and output ranges from 3 to 20.
