ABSTRACT:
A ventilated brake rotor includes two spaced apart annular disks each having an inner diameter and an outer diameter with a locus radius defined radially between the inner diameter and the outer diameter. A series of alternating longer and shorter vanes is distributed around the rotor between the annular disks defining a series of flow passages between each adjacent pair of vanes. Each vane is defined about a curved line with a curvature that is measured from the locus radius, wherein the curved line's curvature is defined by the incoming air flow angle at the flow passage, and wherein the vane profile varies along the curved line so that a non-uniformly curved profile results that maximizes the flow rate through the flow passage. The vane angle and the vane profile result in minimized incidence, viscous and profile flow losses.
