Abstract

Przedmiotem zgłoszenia jest łopata turbiny hydrokinetycznej zawierająca korpus (1) z mocowaniem (2), przy czym korpus (1) ma krawędź natarcia (3) oraz krawędź spływu (4), charakteryzująca się tym, że krawędź spływu (4) zawiera wiele sekcji (41-46) oddzielonych załamaniami, przy czym co najmniej dwa sąsiednie załamania mają różne długości (B1, B11, B2, B22, B3, B33) szkieletowych profilu. Zgłoszenie obejmuje także turbinę drokinetyczną mającą tubularny korpus, w którego osi zamocowane są promieniowo łopaty.The subject of the application is a hydrokinetic turbine blade comprising a body (1) with a mounting (2), the body (1) having a leading edge (3) and a trailing edge (4), characterized in that the trailing edge (4) contains a plurality of sections ( 41-46) separated by bends, where at least two adjacent bends have different lengths (B1, B11, B2, B22, B3, B33) of the skeleton profile. The application also covers a drokinetic turbine having a tubular body with blades mounted radially on its axis.
