Abstract
A fan rotor blade extending radially from a hub is described. The fan rotor blade may include first surface and a second surface, where the first surface and second surfaces are respectively defined by a set of X-coordinates, Y-coordinates and Z-coordinates. The X, Y and Z coordinates can be set out in any of Tables T-1, T-2, E-1, and E-2. The X, Y, and Z-coordinates can also be scaled by a predetermined factor, with the X-coordinates are oriented in a tangential direction, the Z-coordinates are oriented in an axial direction, and the Y-coordinates are oriented in a radial direction.

A fan rotor blade extending radially from a hub, the fan rotor blade including a first surface and a second surface, wherein:
- the first surface and second surfaces are respectively defined by a set of X-coordinates, Y-coordinates and Z-coordinates set out in any of Tables T-1, T-2, E-1, and E-2;
- the X, Y, an Z-coordinates scaled by a predetermined factor;
- and
- the X-coordinates are oriented in a tangential direction, the Z-coordinates are oriented in an axial direction, and the Y-coordinates are oriented in a radial direction, wherein an origin of the X, Y and Z coordinates is at an axial and radial center of the hub.
