Why sweep the propeller blades?
The biggest benefit of propeller blade sweep for the King Air type of airplane is that it allows for a larger diameter propeller that provides greater thrust without increasing the sound level in the airplane and on the ground. Raisbeck's Swept Blade Turbofan Propellers for 90-Series King Airs provide unparalleled performance increases across the entire flight envelope. The Swept Blade Propellers as part of Raisbeck's EPIC Performance Package creates the best-equipped King Air E90 in the field.
