| 摘要 |
<p>The invention concerns a Kaplan turbine wheel comprising a hub (11) and several blades (12) articulated each about an axis (X12) defined by said hub (11). At least one blade (12) is equipped with a mobile element (15) closing a gap (I) defined between an inner radial edge (12a) of the blade and the hub (11) thereby avoiding parasite fluxes and risks for wildlife creatures passing through the turbine.</p> |
