Hartzell Propeller Inc. has received FAA certification for its new ASC-II second generation Advanced Structural Composite propeller system. Hartzell’s ASC-II is the first FAA-certified advanced structural composite propeller developed specifically for the general aviation market.
The ASC-II is an optimized design mated to a proprietary, Hartzell-developed manufacturing process. The result is an advanced structural composite propeller that delivers all of the advantages provided by Hartzell’s first generation of composite propellers — low weight, low inertia, and low life cycle costs — while minimizing the major disadvantage: the high cost manufacturing process.
The Hartzell ASC-II consists of a unique monocoque structure of advanced composite materials. Its carbon/ Kevlar laminate is integrated into a co-molded stainless steel shank. The outboard half of the leading edge is protected with a co-molded electroformed nickel erosion shield. Aluminum mesh is embedded into the laminate for lightning protection.
