Vertical axis wind-powered energy generation plant has each wind turbine rotor blade divided into small and large sections on opposite sides of local horizontal axis

摘要

The energy generation plant has wind turbine rotor blades (1) provided with local horizontal rotation or flexure axes and which are attached to carriers (30) which rotate about a central vertical axis (2) with a central shaft for driving an electrical generator. Each rotor blade is divided into a small section and a large section lying on opposite sides of the local horizontal axis, with a blocking device, e.g. a spring grid (43), only permitting its rotation in a given direction.
