Raisbeck Engineering and Hartzell Propeller have again collaborated and announced its new composite five-blade swept propeller for the Beechcraft King Air 350. The new propellers are an extension of the propeller blade technology advancements developed jointly by Raisbeck and Hartzell for the King Air 90, King Air B200 series and King Air 300 series aircraft. The new five-blade swept propellers replace the standard Hartzell four-blade aluminum-blade propellers currently on the King Air 350.
Utilizing the swept blade technology as an integral part of its design, the Raisbeck Hartzell team has developed an advanced structural composite propeller made of carbon fiber.
Designed to improve passenger comfort and performance, the aerodynamic blade design combined with advanced structural design maximizes thrust, therefore increasing performance while reducing noise for the King Air 350. Other benefits include unlimited blade life, reduced maintenance costs with six years/4,000 hours TBO, three years/3,000-hour warranty, increased takeoff acceleration, and better landing deceleration and accel-stop. The composite five-blade swept propeller provides a total weight savings of 47 pounds compared to the current OEM propeller for the King Air 350.
Supplemental Type Certificate (STC) approval is expected soon, with production by Hartzell immediately following.
Raisbeck Engineering also recently announced that Yingling Aviation has joined Raisbeck’s global network of Authorized Dealers. Founded in 1946, Yingling is a full general aviation services provider at Dwight D. Eisenhower National Airport (ICT) in Wichita, Kansas.
