Composite Propeller for JetPROP DLX

Hartzell Propeller Inc. has developed a four-blade copmostie propeller for the JetPROP DLX, a Pratt & Whitney PT6 turbine conversion of the Piper Malibu/Mirage. The high performance blades of these propellers are construced of Kevlar®, which offers the benefits of lower weight and longer life over conventional metal blades. In addition to improving high altitude cruise performance and reducing the amount of erosion from ground operations, there are additional benefits to the four-bladed Hartzell composite scimitar blade system: lighter weight, enhanced durability and reliability, and unlimited certification life.
