A wind powered turbine engine comprising rotor blades disposed within an outer casing and a half-spherical head located in front of the rotor blades and blocking the inner 50% of the radius of the rotor blades, the casing and head creating an acceleration chamber wherein incoming wind is speeded up and redirect...

A wind powered turbine engine comprising an internalized containment and control chamber, intake enhancement, vacuum induction exhaust port and horizontally rotating rotor. The turbine functions similarly to a steam or gas turbine engine. The radius of the control chamber decreases progressively as it curves around ...

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 sa...
