Hartzell Propeller will supply new lightweight propellers to Piaggio Aero Industries for its third-generation Avanti twin turboprop–the Avanti EVO. For the EVO, Hartzell worked with Piaggio to develop highly swept, wide-chord aluminum alloy propellers that, when combined with changes to the nacelle and engine exhaust geometry, reduce external noise by five dBA, a 68-percent improvement. Cabin noise is also lowered by 20 percent, or one dBA, thanks in large part to Hartzell’s five-blade scimitar design.
