Title: FLOATING WIND TURBINE HAVING TWIN VERTICAL AXIS TURBINES WITH IMPROVED EFFICIENCY
Abstract:
The invention relates to a floating wind turbine (10) comprising a floating platform (14) and a turbomachine (12) resting on the platform, the turbomachine comprising: -first and second transverse flow turbines (24) disposed symmetrically with respect to a first plane, each turbine comprising blades (32) comprising central parts (33) that are extended at the ends by arms, connected to shaft elements (52, 56) by pivoting connections (74, 76), each turbine also comprising upper and lower fairings (42, 44); and - a structure (26) for holding the turbines comprising a vertical median pylon (28) between the turbines and upstream of a second plane containing the axes (A, A') of rotation of the blades of the turbines.
