STALL REDUCTION PROPELLER

摘要

A stall reduction propeller comprising at least one blade (1) connected to an axis (2), where the propeller comprises: ducts (5) arranged along the length of the blade (1); nozzles (6) arranged on the surface of the blade (1) and connected to the ducts (5); a hub (4) connected to the ducts (5); and, a compressor (3) connected to the axis (2) and located inside the hub (4). The compressor (3) generates a controlled airflow which is ducted through the hub (4) and the ducts (5) until it is expelled trough the nozzles (6), allowing the propeller to maintain the boundary layer over the blade.
