Working in total secrecy for the past three years, Raisbeck Engineering and Hartzell Propeller have teamed to develop and certify an all new swept-wing propeller that the companies claim offers greatly improved FAA-certified takeoff, climb and landing performance.
The effort has culminated with FAA certification of the Raisbeck/Hartzell Swept Turbofan Propeller for the King Air 200/B200/B200GT. The new four-blade props are expected to be available to King Air owners starting in March, the companies said.
