Hartzell Propeller Inc. has been selected by Kestrel Aircraft as the propeller supplier for its new all-composite, single-engine turboprop. Working closely with Kestrel, Hartzell is developing a new ASC-II™ structural composite blade to optimize performance through the aircraft's flight envelope and maximize cruise performance, while still providing good low end performance for operations in and out of short runways.

Hartzell's ASC-II™ blade for the Kestrel will be an all carbon monocoque structure with a co-molded electroformed nickel erosion shield. These blades are constructed using an advanced, highly developed Vacuum Assisted Resin Transfer Molding (VARTM) process. Hartzell's true composite blade for the 110-inch diameter, 4-blade lightweight propeller will provide significant weight savings without sacrificing strength or durability.

Kestrel's COO and executive vice-president of product development, Steve Serfling, said, "Hartzell has proven itself as an excellent supplier of propellers on several aircraft platforms, and has demonstrated an ability to implement technical solutions that maximize aircraft performance and safety. Kestrel is pleased to have Hartzell's expertise and knowledge devoted to our project."

Joe Brown, president of Hartzell Propeller Inc., added, "We are committed to having the best, most comprehensive and robust propeller technology in the market. We are extremely pleased to win Kestrel's business and gratified that Kestrel has chosen our ASC-II™ all-composite blade technology. It's hard to beat our true composite blade with its superior combination of outright performance, low weight, and unmatched durability."

Kestrel Aircraft (www.kestrel.aero) is led by general aviation entrepreneur and industry leader, Alan Klapmeier. The company is currently in the process of design and FAA certification of its 6-8 seat, all-composite, single-engine turboprop, which will be powered by the efficient Honeywell TPE331-14GR engine. The aircraft boasts a broad performance envelope, and the newest technologies available in both personal and business aircraft. Kestrel Aircraft is based in Superior, WI, and Brunswick, ME.

Hartzell Propeller is widely recognized as the leader in advanced propeller design and manufacturing technology. The company has developed the next generation of propellers based upon innovative "blended airfoil" technology and is manufacturing these blades using a combination of revolutionary machining centers and robotics; and with its ASC-II™ composite technology, to provide mission-optimized performance for its customers.
