First Glass Fiber Rotor Blades Tested
First all-glass fiber rotor blades will be flying within a year, most likely on an Umbaugh U-18. Other airframe candidates expected to follow shortly are the Kaman H-43, Vertol H-21 and the Bell 11-40 helicopters. Parsons Corp., source of the Umbaugh, Bell and Vertol rotors, has been working on glass fiber blades for six years and is ready for flight production.
