Altitec has been appointed official installation partner by the Renewable Energy Division at 3M, to install its 3M Wind Vortex Generators. 3M Vortex Generators address aerodynamic issues common to most turbine blades and, in doing so, can increase a turbine’s annual energy production by between 2 and 3 per cent.

Rotor blades typically twist no more than 10-20° from root to tip, and while chord length – the width of the blade at a given distance along its length – can vary, these factors prevent wind turbines from achieving optimal aerodynamic performance. In response to these, 3M in partnership with Smartblade has developed its Wind Vortex Generator. They can be easily attached to the rotor blade, resulting in attached flow to enhance performance by guiding wind flow around its surface.
