Propellers with forward sweep were studied in order to determine whether this type of sweep produces a more efficient propulsion source. The sweep effect is achieved solely by tangentially leaning the leading edge of the blades toward the direction of rotation. Eight 155mm (6.1") diameter propeller designs were created for testing; one straight blade, used for comparison, and seven swept blades using different sweep angles and configurations. Wind tunnel tests were conducted on all blades and CFD simulations were made for the straight blade as well as the best performing swept designs from the wind tunnel results. While efficiency values from wind tunnel tests and CFD simulations were not the same, the trends created in both were considered to be comparable. The general trend established shows that the swept blades not only have higher efficiencies but also have greater stall margins. Some speculated reasons for these advantages are given.
