Abstract
The invention relates to a device for converting the kinetic energy conveyed by an aerodynamic or hydrodynamic flow into usable kinetic energy, said device combining the two conventional Savonius and Darrieus configurations, said device being convertible, having a variable geometry, using a composite blade system, and being combined with a mechanical system which enables said conversion, switching from one configuration to the other according to the wind speed and the external conditions. Said turbine starts the cycle thereof in a Savonius configuration and, as the wind speed increases, transforms into a plurality of interlocking Darrieus turbines. This enables the device to use aerodynamic forces such as lift and drag, which complement one another on a number of levels.
