FLIGHT International, 27 September 1962 Fiber glass propellers for U. S. Military V/STOL transport America's XC-142 transport will be a tilt-wing, vertical or short takeoff and landing (V/STOL) aircraft capable of flying 32 troops or 8,000 pounds of equipment directly to combat sites at 300 knots. The aircraft is being developed by Chance Vought with Hiller Aircraft and Ryan Aeronautical. The unusually light, tough propeller blades re quired by the XC-142 will be developed by Hamil ton Standard Division of United Aircraft. These advanced blades will be constructed of fiber glass with a central steel spar. Work at Hamilton Stand ard has shown this concept can reduce propeller weight by as much as 20 per cent. Each XC-142 has five propellers. Four 15H foot four-bladed propellers on the tilting wing provide vertical lift and forward propulsion. A single three- bladed 8-foot propeller mounted at the tail of the aircraft provides attitude control during hovering and during transition to forward flight. These propeller blades are only part of a compre hensive development program underway at Hamil ton Standard for new lightweight VTOL and STOL propeller systems. This work is a natural outgrowth of more than 40 years of designing and producing propellers for aircraft throughout the free world. United Aircraft INTERNATIONAL East Hartford 8, Connecticut, U.S.A.
