Continuing in the company's tradition of applying state-of-the-art technology to the design of high-performance propellers, Raisbeck worked with Hartzell Propeller to bring Composite Swept Blade Propellers to 200 and 300 series King Airs. Noticeably quieter, lighter in weight, damage resistant and commanding more power without added noise, Raisbecks Composite 5-Blade Swept Propellers offer increased performance, strength and payload. Composite blades are manufactured with structural carbon fiber composite over a metal blade shank retention section and nickel cobalt leading edges for superior durability against FOD and improved erosion resistance to environmental conditions. Raisbeck's Composite 5-Blade Swept Propellers also offer operators reduced life cycle costs due to repairability of the blades and the ability to maintain their airfoil shape, resulting in longer blade life expectancy.
