Abstract
An horizontal axis wind turbine having a rotor (3) with a frontal projection comprising a stationary spherical head (1) upstream of its multibladed turbine rotor (3) displaces and increases the speed of wind addressed over 70% of the total frontal area. A series of thin airfoils (12) radially and evenly placed on said spherical head (1) to direct wind towards the turbine short blades (4).
Claims4
A wind turbine with a stationary half spherical projection including the outer surface of its turbine rotor, and extending forward, as a stationary extension thereof, beyond its rotor, for the purpose of speeding up wind addressed by its turbine blades, to improve the efficiency of the said wind turbine, by speeding up wind addressed, by as much as fifty seven percent, subject to probable drag losses of 10 to 20 percent.
A wind turbine with a stationary half spherical projection, not including the outer surface of its turbine rotor, and extending forward, as a stationary extension thereof, beyond its rotor, for the purpose of speeding up wind addressed by its turbine blades, to improve the efficiency of the said wind turbine, by speeding up the wind addressed, by as much as fifty seven percent, subject to probable drag losses of 10 to 20 percent.
A wind turbine with a stationary half spherical projection including the outer surface of its rotor, and extending forward beyond the said rotor, as a stationary extension of the said sphere, which effectively displaces a major portion of the total frontal area of the wind turbine, including that of its entire rotational arc, to the extent of 70 percent or more, of the radius of the said rotational arc from axle center to its blade tips, to access a greater amount of the energy from all of the wind directly addressed by the blades of the said wind turbine.
