Abstract
A unshrouded vane assembly for an unducted propulsion system includes a plurality of vanes which have non-uniform characteristics configured to generate a desired vane exit swirl angle.
Claims20
A thrust producing system, comprising:
- an aircraft structure comprising an aircraft surface;
- an unshrouded rotating element;
- a vane assembly located aft of the rotating element;
- wherein at least a portion of the aircraft surface is merged along an axial direction with the vane assembly.
1 more element
A thrust producing system, comprising:
- an aircraft structure comprising an aircraft surface positioned at one or more of a pylon, a fuselage, or a wing;
- an unshrouded rotating element;
- a drive mechanism configured to provide torque and power to the unshrouded rotating element, the drive mechanism connected to an aircraft by the aircraft structure;
- an unshrouded vane assembly located aft of the rotating element;
- wherein at least a portion of the aircraft surface is merged along an axial direction with the vane assembly, and wherein at least the portion of the aircraft surface is positioned along a circumferential direction between two vanes of the vane assembly.
2 more elements
A thrust producing system for an aircraft, comprising:
- an aircraft structure comprising a fuselage and a pylon, wherein the pylon comprises a leading edge;
- an unshrouded rotating element;
- a drive mechanism configured to provide torque and power to the unshrouded rotating element, the drive mechanism connected to an aircraft by the aircraft structure;
- an unshrouded vane assembly located aft of the rotating element and rotationally fixed in relation to a longitudinal axis of the drive mechanism, wherein the unshrouded vane assembly comprises a plurality of vanes positioned along a circumferential direction;
- and
- wherein at least a portion of the leading edge of the pylon is merged along an axial direction between two vanes of the unshrouded vane assembly.
