  • Propeller for an aircraft propulsion assembly, propulsion assembly, and method for the use of such a propulsion assembly
    Patent number: 12534185
    Abstract: A propeller for an aircraft propulsion assembly extending longitudinally along an axis X. The propeller comprising a propeller cone, blades, a guide member extending longitudinally along the axis X and rotating as one with the propeller cone, the guide member being mounted outside the propeller cone in such a way as to form between them a guide path, the guide member having an upstream opening configured to convey a flow of air in the guide path and a downstream opening in such a way as to remove the flow of air downstream, the guide member having through-orifices through which extend the blades of the propeller and compressor vanes, which rotate as one with the propeller cone and which are positioned in the guide path in such a way as to generate an accelerated air flow.
