air through apertures 55 in end bell 42 in a direction from right to left between stator 36 and rotor 34 in fig1 and 4 thus the cooling air moves through the interior of the alternator in a direction opposite from the air passed over the exterior of alternator by the wind turbine blade 44 as indicated by the arrows in fig1 and 4 a lightweight wind turbine blade 44 formed of fiberglass is fastened by appropriate means with a nut 46 on a threaded portion of the front end of rotor shaft 33 so that blade 44 operates in a plane normal to shaft 33 the wind turbine blade 44 thus directly drives the rotor 34 i e without the use of speed increasing gears a wind turbine blade hub 45 is disposed forward of blade 44 to effeciently direct the air flow adjacent the center of the blade and over the alternator housing 20 the current output produced by the stator winding 37 is passed to flexible output wires 48 electrically connected to slip rings 11 on swivel pin 7 pole 8 supports a pair of brushes 49 spring biased to contact the slip rings 11 for transfering electric current to a stationary wire 50 to the alternator load not shown to the lower rear portion 4 of swivel frame 2 is attached a primarily downwardly extending generally flat v shaped guide vane 51 formed of heavy gauge steel sheet metal for directing the front portion 3 of swivel frame 2 into the wind it should be noted that in fig1 the upper leg of the v of planar guide vane 51 does not extend above rotor axis 40 which always is maintained.
