Title: A wind turbine and method of generating power from the wind
Inventor: ELOGAB OSAMA
IPC: F03D1/06
Filed: 2020-09-08
Abstract: The blades of conventional wind turbines are almost pitch adjustable, and by pivoting about the longitudinal direction, the angle of elevation of the blades with respect to the wind can be changed. This function is necessary because the effective elevation angle varies with wind speed and rotational speed. In particular, if the wind speed is very high, the blades can feather and reduce the amount of torque to be transmitted to the turbine. The present invention provides a wind turbine for supplying compressed air to air outlets (21) on a blade (1). In this way, it is possible to control the aerodynamic behavior of the blade (1), so that the blade can be feathered without the need for a mechanism to pivot the blade.
