Abstract

This paper shows the structural design of a composite water current turbine rotor by the finite elements method (FEM) [1]. The mechanical and geometrical parameters involved in the design of this fiber reinforced composite material are fiber orientation, number of layers, stacking sequence and laminate thickness. The results are generated through the simulations in a FEM code about the rotor behavior (stresses and strains) under applied water pressures. The main purpose is to achieve a very low inertia rotor, because it is applied in an axial water flow turbine currently in study by the authors, where it is important to take the maximum advantage of the kinetic energy. The FEM simulation is engineered by CIMNE�s (International Center for Method in Engineering) software: ComPack-Aero [2] in Barcelona (Spain). To complete the analysis, the stiffness and the state of stress of the composite rotor is compared with results corresponding to a steel one. So in that way it is possible to select the best option to use in this turbine rotor.
