| titleOfInvention | Turbine rotating fan blades, fan and turbine provided with the fan |
| abstract | The invention relates to a turbine rotating fan blade (2) having a predetermined breaking area (5) extending from an upstream edge (22) along a given length (L) and at a given Extends in height (H) from the blade tip edge (27). According to the invention, the body is made of a composite material comprising a fiber reinforcement (4) obtained by three-dimensionally weaving the warp and weft strands (41, 42) and a resin matrix (4) in which the fiber reinforcement (4) is embedded. 43), and the main body has discontinuities (6) in at least some of the strands in or near the region (5), the discontinuities being configured such that when there is a difference in thickness direction (EP) to the blade tip edge (27) With tangential friction of , the area (5) is partially separated, and the height (H) is less than 3% of the aerodynamic flow path height (HVA) of the blade (2). |
