Northwest Helicopters unveils carbon fiber main rotor

The blade, for the UH-1H and Bell model 205 and 212 helicopters, is built with a carbon fiber-reinforced composite spar, Nomex honeycomb core and carbon fiber skins.

Northwest Helicopters (Olympia, Wash.) unveiled its new main rotor blade for the UH-1H and Bell model 205 and 212 helicopters at Heli-Expo 2009 in February. Built with a carbon fiber-reinforced composite spar, Nomex honeycomb core, carbon fiber skins, and a stainless steel leading edge, the blades are committed to military and public use agencies this summer after completion of flight and fatigue testing. Northwest expects U.S. Federal Aviation Administration (FAA) certification in fourth quarter 2009.
