McCauley Propeller Systems (Wichita, Kan.), a part of Textron Aviation (Wichita, Kan.) showcased the Blackmac Carbon Series constant speed composite propeller at this year's Sun 'n Fun international fly-in and expo (April 1-6, Lakeland, Fla.).

The clean sheet scalable design features advanced composite materials and a patented high-strength, low-weight continuous carbon loop blade retention system, which significantly reduces weight and improves product life. It is expected to receive FAA certification in the first half of 2014.

“The Blackmac Carbon is the next step in propeller evolution,” said Scott Howell, McCauley business leader. “This new propeller is the lightest in its class. No other certified propeller rated at 350 hp, wood or composite, weighs less. The Blackmac Carbon series retains McCauley's widely popular and proven single-piece oil-filled hub and has 25 percent fewer parts than comparable aluminum propellers.”

The scimitar propeller blades, optimized for balanced performance, are reportedly made of seamless carbon and glass fiber material and feature electro-formed nickel leading edges to provide improved durability and impact resistance.

The Blackmac Carbon Series is certified for unlimited life and an overhaul interval of 2,400 hours or 72 months. McCauley claims it is the world's largest full-line propeller manufacturer, designing and manufacturing high-quality propellers and systems for the commercial, general aviation and defense industry for more than 75 years.
