British rotor technology pioneer Blade Dynamics has been hired by the UK government-backed Energy Technologies Institute (ETI) to develop blades up to 100 metres long for the coming generation of 8-10MW wind turbines.

Through the £15.5m ($24.9m) project, the Isle of Wight-based company will fabricate a series of blades 80-100 metres in length that use ultra-stiff carbon-fibre rather than conventional fibre-glass in their construction.

The prototype blades – slated to be put into production by late-2014 – would be the world’s longest, outstripping current record-holder Siemens’ 75-metre B75 blade.

Blade Dynamics’ blade designs employ an innovative design and manufacturing process that constructs them through the assembly of smaller, more easily manufactured component pieces, rather than from extremely large full-length mouldings.
