Generator and fan

Abstract

An improved generator fan serves to draw air into the generator through an inlet in the generator housing, pass the air through the rotor and stator, and direct the air out openings in the generator housing. The fan of the present invention includes a disc and at least one multi-directional blade extending from the disc. The multi-direction blade includes a leading segment extending from the disc between a first radius measured from the axis of rotation and a second radius, the leading segment including a leading edge extending from the disc at an angle of about ninety degrees from the disc, the leading segment extending from the disc with an increasing angle along the length of the leading segment; and a trailing segment extending from the disc between the second radius and a third radius measured from the axis of rotation, the third radius being greater than the second radius and the trailing segment extending from the disc with an angle having a rate of change different than the leading segment.

1 . A generator fan, comprising: 
 a disc adapted to be centrally mounted perpendicular to an axis of rotation and at least two multi-directional blades extending from the disc, the multi-directional blades including:    a leading segment extending from the disc between a first radius measured from the axis of rotation and a second radius measured from the axis of rotation, the leading segment including a leading edge extending from the disc at an angle of about ninety degrees from the disc, the leading segment extending from the disc with a swept out shape starting at the leading edge and extending from the disc with an increasing angle along the length of the leading segment; and    a trailing segment extending from the disc between the second radius and a third radius measured from the axis of rotation, the third radius being greater than the second radius and the trailing segment extending from the disc with an angle having a rate of change different than the leading segment;    wherein said multi-directional blades further include an arced interface with said disc; and    wherein said multi-directional blades overlap one another so that the leading segment begins proximal the second radius of an adjacent multi-directional blade.    
   
   
       2 . A generator comprising: 
 a generator shaft defining an axis of rotation;    a fan including a disc mounted on the shaft and at least one multi-directional blade extending from the disc, the multi-directional blade including:    a leading segment extending from the disc between a first radius measured from the axis of rotation and a second radius measured from the axis of rotation, the leading segment including a leading edge extending from the disc at an angle of about ninety degrees from the disc, the leading segment extending from the disc with a swept out shape starting at the leading edge and extending from the disc with an increasing angle along the length of the leading segment;    a trailing segment extending from the disc between the second radius and a third radius measured from the axis of rotation, the third radius being greater than the second radius and the trailing segment extending from the disc with an angle having a rate of change different than the leading segment;    at least one uniform blade having a uniform angle from the disc; and    a flow port between said multi-directional blade and an adjacent blade.
