The 80-inch diameter, 2-blade, scimitar-shaped composite propeller system with Kevlar spinner weighs only 42 pounds, company officials report.
The life-unlimited, repairable composite blades are protected with nickel-cobalt leading edges that provide 60% more protection, according to company officials.
Calibrated flight tests on the Aviat Husky test plane indicated the Ultra was 4% faster in cruise (5 mph) and 9% improved in climb, officials add.
Additionally, the new prop is quieter, smoother and utilizes a new paint process that virtually eliminates paint erosion, company officials note. Just like all MT Husky props, this one also is able to be operated with no “restricted RPM” ranges on all engines.
Current Flight Resource STCs are being amended to include this propeller for all Aviat Huskies, American Champion Scouts and Cessna 170, 172 and 175 that are powered by the Lycoming 360/390 series engines, company officials conclude.
