this week launched two- and three-blade versions of its new swept-tip Advanced Structural Composite Trailblazer prop for homebuilts and several other production types specifically designed for bush and backcountry flying.
The two-blade version is compatible with most Lycoming 360 and 390 series engines, with no placards or restrictions, and is available in 78-, 80-, and 83-inch diameters. The three-blade version is available for higher horsepower applications in 80-, 82-, and 85-inch diameters. Hartzell is working with numerous aircraft manufacturers to pursue approvals to install the new Trailblazer propeller on certified aircraft.
All have unlimited blade life and are approximately 20 percent lighter than comparable propellers with aluminum blades.
"Backcountry flying is all about getting into remote landing areas, but once you're in you have to get back out," said Hartzell Propeller President Joe Brown, who installed a Trailblazer on his Glastar Sportsman. "The takeoff acceleration and climb performance of the new Trailblazer prop gives me the added performance I want for backcountry flying."
The swept-tip, scimitar shaped airfoil is designed for optimal take-off acceleration and climb performance, resulting in an increase of 80-100 fpm climb rate and three-knot cruise speed improvement versus a three-blade wood core propeller, according to Hartzell.
The Trailblazer's all carbon fiber construction features an innovative mesh erosion shield and field replaceable nickel-cobalt leading edge to withstand demanding backcountry and bush flying. They're more than five to 10 times stronger than beech wood and spruce, respectively, and include Hartzell's state-of-art wedge shank blade retention design.
Sun 'n Fun International Fly-In & Expo attendees can view the new prop at the Hartzell exhibit (B-034/35) April 1-6 in Lakeland, Florida, or see an installed example on a Sportsman at Glasair Aviation's static display (MD-017B).
