Claims31
An unshrouded vane assembly for an unducted propulsion system comprising a rotating element and a vane assembly, the vane assembly having a plurality of vanes, wherein the plurality of vanes are configured to impart a change in tangential velocity of the air opposite to that imparted by the rotating element, and wherein the plurality of vanes have non-uniform characteristics with respect to one another and are configured to generate a desired vane exit swirl angle.
An unducted propulsion system, said propulsion system comprising a rotating element having an axis of rotation and a stationary element, said rotating element having a plurality of blades each having a blade root proximal to said axis, a blade tip remote from said axis, and a blade span measured between said blade root and said blade tip, wherein said stationary element has a plurality of vanes, the plurality of vanes each having a vane root proximal to said axis, a vane tip remote from said axis, and a vane span measured between said vane root and said vane tip, and wherein the plurality of vanes are configured to impart a change in tangential velocity of the air opposite to that imparted by the rotating element and wherein the plurality of vanes have non-uniform characteristics with respect to one another and are configured to generate a desired vane exit swirl angle.
