Northwest develops composite Bell blades
Northwest Helicopters (Booth No. 2989) has developed carbon-fiber main rotor blades for the Bell UH-1H, 205 and 212. STC approval is expected by the end of 2009. Northwest said the blades will have longer life limits, improved high/hot performance, decreased fuel flow and dual trim tabs for a smoother ride. First year production of UH-1H blades already is sold out, according to the company. The new blades will be supported exclusively by IAC of Dallas.
