Energy seems to be the world’s one, the only and the most important problem at the moment. To be specific it’s the production of energy in an ecological, economical and renewable manner, which is keeping the researchers very busy and up all night. Since more than half a century, researchers have been looking into ways of developing power with inexhaustible, replenishable and ecological means.To this end almost from the dawn of modern technology natural resources have been exploited. In the past nature was exploited in its modified state. That is by building dams and river wheels/turbine. Now though the emphasis on extracting energy from the nature while leaving it relatively unaffected. For having environmentally friendly renewable energy sources researchers have been looking to harness the power of the sun and the wind. There is a huge abundance of these two sources. However solar energy being available only a fraction of the time of the day, wind energy having chosen a suitable location can be continuous.Once a location for wind energy convertors or wind turbines has been chosen the research then turns to convert the energy efficiently, cheaply and safely. Also the use of offshore wind resources where the turbines are placed in the seas are studied. It is seen that offshore units have their advantages the most important of which is the freeing up of space on land for agriculture, industry and housing. Once offshore, why stop near the coast? Why not go into deeper waters and capture the energy available in open seas also. Hence wind energy extraction technology is ever developing to find exploitable areas.This PhD research work entitled “Identification and characterization of mechanical and structural properties under static damage and fatigue of a composite floating wind turbine blade” looks into the various aspects of the floating wind turbine blade design. Experimental and numerical techniques are developed to accelerate the design process and possible design optimization proposals are also given. |
