McCauley Propeller Systems has announced that the US FAA has certified the company’s Blackmac Carbon Series constant-speed composite propeller.
The company says the propeller’s advanced composite materials and patented high-strength, low-weight continuous carbon loop blade retention system significantly reduces propeller assembly weight and improves product life.

“The low weight of the Blackmac Carbon Series propeller, offers the ability to improve payload without compromising strength or weight in other areas,” McCauley Business Leader, Scott Howell said.
The scimitar propeller blades are made of seamless carbon fibre and fiberglass material and feature electro-formed nickel leading edges providing a stronger, more durable and impact-resistant product. The prop has been certified with no set maximum life, and with an overhaul interval of 2,400 hours or 72 months.
Wow, no set maximum life and 6 years between overhauls! This sounds like a pretty cool prop!

I wonder what the process is for smoothing out rock dings from the leading edges of this propeller. “Electro-formed nickel leading edges” are a new technology. Will filing them down (as is done with all metal propeller blades) compromise the structure?

Metal leading edge guards are fairly standard features on composite and wood propellers. Sometimes nickel or stainless steel. When the leading edges get banged up they just replace the metal guards.
