Abstract:
An assembly of jet assisted counter rotating wind turbine comprising:(a) windward rotor having blade airfoils set to rotate in clockwise direction and mounted on the inner shaft of a co-axial transmission device that includes a permanent magnet rotor of an alternator,(b) a leeward rotor having said airfoils set to rotate in anti-clockwise direction and mounted on the outer shaft of said co-axial device including a wound armature of said alternator,(c) a pair of radial and thrust load bearings fitted between said co-axial shafts that serve the dual purpose of said alternator and said power transmission means,(d) an axial air compressor that is fixed to the outer rotating shaft and electrically linked to said alternator, and supplies compressed air to said leeward rotor,(e) a main bearing designed to withstand axial and radial loads fitted on to said outer shaft,(f) a pair of slip rings attached to said outer shaft to transmit electrical energy from said alternator to an external load,(g) a swivel platform to support said main bearing including a pair of slip ring brushes for energy transmission,(h) a tubular mast to support said swivel platform including the wind turbine unit,that provides substantially enhanced energy production, lighter and durable structure requiring minimal maintenance, and an ability to produce electrical energy even in low speed wind environment.
