Hartzell Rolls Out Composite King Air Propeller

Hartzell's new, five-blade structural composite propeller is expected to improve performance for Beechcraft King Air 200 series turboprop twins. According to Hartzell (Booth C7235), the swept propeller will be available from Raisbeck Engineering (Booth C11443) through its STC for King Air 200, B200, and B200GT. “This latest performance improvement for the King Air 200 series extends the longstanding and excellent relationship between Raisbeck and Hartzell,” said Hartzell executive v-p and general manager J.J. Frigge 

Constructed of structural carbon fiber composite with nickel cobalt leading edges to safeguard from foreign object damage, the propeller optimizes airfoil efficiency, allowing for a larger 96-inch diameter prop with less blade tip noise. It weighs 48 pounds less than OEM-installed propellers and boosts runway acceleration and engine-out climb scenarios with flaps up. Unlimited blade life is expected to lower maintenance and overhaul costs.

It is the first five-blade structural composite propeller certified on the King Air series. Deliveries of the propeller are expected to begin next month.
