King Air 350S Improved by Hartzell Propeller and Raisbeck Engineering

Established in 1917 by Robert Hartzell, Hartzell Propeller is a global leader manufacturer of composite and aluminum propellers for certified, homebuilt and ultralight aircraft. Piqua, Ohio is the location of its headquarters.

On the other hand, Raisbeck Engineering is a supplier of aircraft adjustments for business and commercial aircraft. Their main goal is to improve passenger comfort and to convey better performance solutions.

On 24th July, in Oshkosh, Wisconsin, Hartzell Propeller and Raisbeck Engineering are working together on a new structural compound swept blade props for the Beechcraft King Air 350 turboprop. At EAA AirVenture Oshkosh 2017, Hartzell Propeller’s exhibit will present a King Air 350 altered by Raisbeck Engineering with Hartzell’s latest structural compound over 250 cm diameter lightweight five – blade propellers.

The airplane will be exposed at Hartzell’s Booth 296-297 in the Main Aircraft Display Area during EAA Airventure july 24th through July 30th. Hartzell was the designer and manufacturer of the King Air propellers, while Raisbeck ran the flight tests for the STC, which is awaited soon.

JJ Frigge, Hartzell’s Propeller Executive Vice President said “By taking advantage of the aerodynamic effect of blade sweep, the strength of lightweight structural composites and robotic manufacturing technologies, Raisbeck and Hartzell have greatly improved performance across the board in all flight phases.”

The five blade swept propellers substitute the typical Hartzell four blade aluminum blade propellers. Furthermore, the vice President of Sales and Marketing, Lynn Thomas also added : “This lighter prop provides improved single-engine climb performance, unlimited life blades, increased takeoff acceleration, and is quieter. We are already receiving widespread interest from King Air 350 owners and operators in this high performance aftermarket modification.”
