Extraction of energy from wind depends on the design of blade. In this paper, the authors based on the blade element theory (BET) and the model of an optimum rotor developed by Glauert’s to design a 1000-mm-long horizontal axis turbine blade model. This model was then used for the finite element analysis. The authors also used the code of the commercial finite element ANSYS to conduct analyses. The results from the linear static structural analysis revealed that the best design provides adequate stiffness and strength to produce the proposed power without any structural failure.

Much has been learned from the advances in wind turbine blade design, but many differences exist that must be addressed. Also, most wind turbine blades are hollow to reduce self-weight and cost, but this type of design is not practical for an ocean current turbine blade. If water were to leak into the hollow region, via a crack, the system would become negatively buoyant and sink, and could possibly damage other units in the array. Wind turbines [2], [3], [5], [6], [10], are subjected to very specific loads and stresses. Due to the nature of wind, loads are highly variable. Varying loads are more difficult to handle than static loads because the material becomes fatigued. Moreover as a working medium the air is of low density so that the surface required for capturing Page 26 energy must be large. The change of the shape of blade [10], .
