New high profitable wind turbines

摘要

To generate more quantities of electric energy from wind it s necessary to use a new type of wind turbine built in the regulable mantle's nozzle. This wind turbine type replaces the free air stream for wind by a programmed, i.e. regulated, and partially concentrated stream of air. The nozzle shell is designed as an aerodynamically shaped ring with wings with its lower pressure side pointed towards the centre so that the lift force on each part of the wing is directed radially towards the centre. This induces centrifugal reaction force in the airflow that causes the stream field to expand strongly downstream of the rotor and includes a greater number of streamlines in the active stream in front to the rotor (upstream).
