Title (EN) EXPANDABLE IMPELLER PUMP
(FR) POMPE A TURBINE EXTENSIBLE
Abstract:
(EN) An impeller according to an example of the present invention comprises a hub, and at least one blade supported by the hub. The impeller has a deployed configuration in which the blade extends away from the hub, and a stored configuration in which the impeller is radially compressed, for example by folding the blade towards the hub. The impeller may comprise a plurality of blades, arranged in blade rows, to facilitate radial compression of the blades. The outer edge of a blade may have a winglet, and the base of the blade may have an associated indentation to facilitate folding of the blade.
(FR) 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.
