Abstract (en)
[origin: EP2762728A2] The turbine (1) has a front support (2) forming an effluents input ring. A set of blades (4) extends between the front support and a back support (3). Each blade includes a hollow profile comprising a portion of blade trapped in the back support to form a single part. Each blade comprises two embossings approximately parallel with each other and extending on circumferences from the blade. The embossings define the portion of blade trapped in the back support for forming a thrust. An independent claim is also included for a method for manufacturing a turbine for a centrifugal fan.
