About the Project

The UK has the world’s largest offshore wind farms, consequently it is now the most attractive location for offshore wind investment in the world, attracting investment opportunity of up to £21bn by 2020. Significant technological advances over the last decade have made it possible to capture offshore wind energy efficiently and to reduce the price of electricity generation. These advances have led to large offshore wind turbines with lighter, more flexible blades with considerably larger blade length. This however, has introduced significant aeroelastic instabilities, such as blade stall-induced vibrations and flutter, which have resulted in many catastrophic failures of wind turbine blades. Preventing the aero-elastic and other structural issues for the next generation of wind turbines is a bigger challenge as they are expected to have even larger turbine diameters compared with the current-generation of commercial wind turbines. The proper selection of material important plays a major role in the structural integrity of the wind turbine blades. The objective of this investigation is to develop p new metallic alloys and to optimize the specific strength through control of the composition and the cooling rate. The mechanical behavior will be assessed from tension, compression, 3 point bending test and the performance will be compared with that of a new model.

This project is supervised by Dr Mohammad Rahmati.
