The advantages of the composite materials applied in helicopter main and tail rotor blade designs (high allowable variable elongation, specific strength, corrosion resistance, "soft" failure mode) are well known. The Mil helicopters are produced in large numbers. This fact, as well as the requirement for maintaining stab le strength properties of the blade have called for developing such a blade design and such production procedures that can ensure automated blade manufacturing. This design and technology using numerically controlled machines for laying up tapes have been developed, and the latter are used for manufacturing of experimental and production blades. A unique design of the reliable attachment fitting has been developed. The blades are fitted with an electro-thermal de-icing system made of non- metal composites as well.
