Abstract
A design methodology of composite blades for weight reduction is developed and applied in NASA Heavy Lift Rotor Systems Investigation. The designed blades satisfy the targeted weight reduction and meet all the design requirements including stiffness, strength, stability and performance. The blade stress and strain are analyzed to correlate Tsai-Wu strength design criterion with the industrial design practice - laminate Strain allowable. The parametric studies of material properties about the blade design are conducted. The effect of the active blade load management on the low weight rotor blade design is also investigated. The results show that both material properties and the active blade load management can significantly influence the blade structural design. The blade using all graphite materials is compared to the blade using glass fibers for skin, and the tradeoff is discussed.
