Abstract

L'invention concerne une turbine qui, dans un exemple, comprend un moyeu et au moins une pale reliée au moyeu. Cette turbine possède une configuration déployée dans laquelle la pale s'étend à partir du moyeu, ainsi qu'une configuration repliée dans laquelle la pale est compressée de façon radiale, c'est-à-dire repliée autour du moyeu, par exemple. La turbine peut comprendre plusieurs pales disposées en rangées, ce qui facilite la compression des pales. Le bord externe d'une pale peut comprendre une ailette, et la base de la pale peut comprendre un renfoncement associé facilitant le repli de la pale.
