This invention describes a new lightweight high strength structural design for rotors used in turbines for fluid kinetic power generation or conversion with the aims of reducing rotor mass while maintaining rotor strength or increasing strength without increasing material costs significantly. The basic concept is to use a set of guy wires attached to rotor blades so that each blade is supported at multiple positions along the blade span. Between two adjacent support positions, the length of unsupported overhanging blade section is reduced as compared to the whole blade length. Fluid dynamic loading induced bending and shearing along the blade can thus be reduced significantly.
