Hartzell Propeller Develops New 3-Blade ASC-II Composite Propeller for Van's Aircraft

24 July 2012

Hartzell Propeller has developed a new 3-blade ASC-II composite propeller for Van’s Aircraft RV-10.

According to Hartzell, the new prop is four pounds lighter than Hartzell’s previous model due to the certification of a lighter-weight hub. It’s available to order directly through Van’s Aircraft. Hartzell will deliver the first of its new props to Van’s Aircraft in August, 2012.

Hartzell says its 3-bladed composite propeller noticeably improves the smoothness of flight on the RV-10 when compared to the 2-bladed aluminium propeller. The ASC-II’s proprietary blade design features a carbon fibre monocoque construction with co-moulded leading edges of electroformed nickel for erosion resistance.

Gus Funnell, Van’s Aircraft, Technical Support, said “Hartzell’s 2-bladed blended airfoil prop for the RV-10 is a great performer and their new lightweight 3-blade composite propeller is noticeably smoother without giving up much performance. We’re happy to offer our customers either option directly through our catalogue to our customers, worldwide.

"Hartzell continues to be the overwhelming choice for RV owners who want the performance of a constant-speed propeller."

Rob Hickman, President of Advanced Flight Systems said, “I couldn’t be more impressed with my Hartzell ASC-II composite propeller. Since installing Hartzell’s prop I’ve noticed a huge difference in my aircraft’s smoothness while in flight - it makes cruising my RV-10 even more enjoyable.”

He added, “When I fly with other pilots they almost always comment on how smooth my RV-10 flies, and I attribute this directly to my Hartzell propeller. Also, it’s got terrific ramp appeal.”

Hartzell’s Senior VP, Marketing and Customer Service, Mike Disbrow, said “This new propeller for Van’s Aircraft RV-10 knocks four pounds off our previous model. A weight saving like this, at the front of the aircraft, can make a significant difference to the plane’s Center of Gravity (CG) and loading.”

Hartzell says FAA Type Certification of the propeller also reduces owners’ fly-off requirements so they can get in the air sooner. When mounted to a certified engine, such as the Lycoming IO-540, fly-off requirements are reduced to 25 hours, instead of 40 hours, which is the standard for experimental aircraft like the RV-10.
