Abstract: A vaneaxial blower system has an axis of rotation and includes a stator and a rotor fan. The stator and the rotor include blades. Each blade extends from a leading edge to a trailing edge. An angle beta of each blade is defined as a slope of a camber line at a location along a span of the blade. An angle theta of each blade is defined as an angle measured between a vertical axis extending through the axis of rotation and a radius at the location along the span of the blade. The angle beta and the angle theta for the blades are selected to provide improved performance of the vaneaxial blower system.

Abstract: A vaneaxial blower system having a stator and a rotor is disclosed. Each of the stator and rotor have a hub and blades, each of the blades have a leading edge and a trailing edge, an angle theta defined by a line extending from the respective leading edges to the respective trailing edges and the respective hub and an angle beta defined as an angle measured between a camber line between a first blade and a second blade and a horizontal tangential line that extends through respective leading edges of the first and second blade.
