The new propeller has been available as an STC option for new aircraft from the factory since earlier this year.
Hartzell’s new offering is supplied with a polished aluminum spinner assembly and is available with or without ice protection. It is available from prop shops, FBOs, or direct from Hartzell under the company’s Top Prop program.
The 78-inch diameter Odyssey features “advanced structural composite blade technology that delivers low weight, low inertia, high durability, and low life cycle costs,” according to Hartzell officials.
Flight testing confirmed that the Odyssey is more than six knots faster and results in a 14% improvement in climb performance versus any other four-blade offering, company officials continued. The Odyssey has a one knot speed improvement and a 5% climb improvement over the standard three-blade propeller, officials add.
The Odyssey propeller offers nearly 2.0 dB(a) reduction in cabin noise and a certified 2.0 dB(a) reduction in fly-over noise versus the standard three-blade propeller, Hartzell officials noted.
The four-blade Odyssey was specifically designed to maximize performance on the SR22 and SR22T and utilizes an advanced carbon fiber composite airfoil integrated into a co-molded aluminum shank, according to company officials. The outboard half of the leading edge is protected with an electroformed nickel-cobalt erosion shield, and the blades are certified for unlimited life, they add.
The propeller comes with a six-year/2,400-hour warranty, which covers the propeller through first overhaul.
