The use of 3M Wind Vortex Generators provides a fast, economical way to address aerodynamic blade issues caused by limited twist and chord length at the blade root. An increased annual energy production of 2 to 3% has been confirmed in different case studies.
Global blade access, repair, and inspection specialist, Altitec, has been appointed official installation partner by the Renewable Energy Division at 3M, a global innovation company, 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%.
Rotor blades typically twist no more than 10 to 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. This can often lead to undesired airflow separation (known as aerodynamic stall) and has a significant impact on turbine efficiency and noise generation.
In response to these issues, 3M has partnered with Smartblade to developed its Wind Vortex Generator, a reliable and quickly installed thermoplastic aerodynamic enhancement. These devices can easily be attached to the rotor blade, resulting in attached flow to enhance performance by guiding wind flow around its surface.
“In the Vortex Generator, 3M has hit upon an excellent way to address this problem, and we’re looking forward to working with them to roll it out across the world,” commented Tom Dyffort, Managing Director, Altitec Group.
3M Wind Vortex Generators are attached to the root section of a wind turbine blade on spots that are determined using a proprietary analysis process. They help improve performance by energizing flow around the surface. This helps reduce flow separation and increases the performance of the entire turbine, in terms of power, loads and service life.

“As one of 3M’s official installation partners, Altitec has completed trial installations at sites in Poland, Spain, and Portugal, and hopes to carry out further installations in Chile in the near future.”
Vortex Generators have undergone extensive testing and analysis to ensure negligible increases in load and deflection when installed. It has been shown that by reducing stall, they help optimise a turbine’s load characteristics while reducing noise. Altitec, in partnership with 3M and Smartblade, statistically analyzes each turbine to ensure the Vortex Generators are positioned to maximize the annual energy production yield of the turbine.
“Vortex Generators are a financially and technologically economical solution, which helps to optimize the aerodynamic efficiency of the blade and improve turbine annual energy production,” said Santhosh Chandrabalan, Global Business Manager at 3M. “We are delighted to have partnered with Altitec, whose specialist knowledge and experience in the field allows this product solution to be widely implemented.”
In addition to their durability and easy application, Vortex Generators can also be adapted to fit almost any blade type, regardless of a turbine’s manufacturer. They not only reduce flow separation, and increase turbine energy yields, they also reduce stall induced loads and help extend service life.
