Abstract:
A generator fan, comprising:a disc adapted to be centrally mounted perpendicular to an axis of rotation 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; 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.
