Hartzell Propeller announced that it has developed a new three-blade ASC-II composite propeller for Van’s Aircraft RV-10. The new prop is four pounds lighter than Hartzell’s previous model, with most of the weight reduction attributed to its lighter-weight hub. A weight savings of four pounds so far forward of the center of gravity is significant for the RV-10, which tends to be a tad nose-heavy when being flown with just the pilot and no bags, passengers or ballast aft of its center of gravity.
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.
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.
The propeller is available to order directly through Van’s Aircraft. Hartzell says it will deliver the first of its new props to Van’s Aircraft in August, 2012.
