Title (EN) DUAL HYDROTURBINE UNIT
(FR) UNITE A DEUX TURBINES HYDRAULIQUES
Abstract:
(EN) An environmentally non-intrusive multiple turbine unit (210) for adjustable deployment in water. The turbines are captured in a shroud (260) having an integrally formed augmentor ring (266) and ballasting member (290) to improve efficiency. The multiple turbine arrangement effectively counteracts the rotational counter-torque of individual turbines, thereby enabling stable deployment of the unit without requiring rigid stabilizing structures.
(FR) L'invention concerne une unité comprenant plusieurs turbines non-intrusives pour l'environnement (210), destinée à être installée de manière réglable dans l'eau. Les turbines sont enfermées dans une enveloppe (260) possédant un anneau augmentateur formé d'une seule pièce (266), et un élément de ballastage (290) destinés à améliorer leur efficacité. L'agencement de plusieurs turbines contrecarre efficacement le couple de réaction de rotation des turbines individuelles, ce qui permet l'installation stable de l'unité sans avoir besoin de structures de stabilisation rigides.
