A group of researchers are studying a design inspired by the wings of the Andean condor, promising to increase energy production by capturing more energy from wind turbines by 10%.
The condor’s wings inspire the shape of new wind turbines
This approach mimics the curved limbs of various birds, whose wings end in raised tips that maximize lift and are already applied in aviation . However, its implementation on the huge wind turbine blades represents a novelty.
Additionally, Khashayar Rahnamaybahambary of the University of Alberta explains the practical difficulties of obtaining experimental data on full-size turbines, which led his team to turn to simulations. These fins, modeled after the condor, which weighs up to 15 kilograms and flies great distances, could significantly reduce air resistance.
Power generation is possible
Preliminary simulation results are promising , suggesting that the incorporation of these fins could improve the energy efficiency of wind turbines. “These types of fins not only capture more energy from the wind, but also minimize drag losses,” adds Rahnamaybahambary.
The design of the fins allows them to be installed on produced turbine blades , through a process that the researcher compares to putting a sock on the end of the blade. Currently, a prototype is being developed to test this theory in real conditions.
Finally, Peter Majewski, a retired expert, considers the findings consistent with aerodynamic engineering . Although retrofitting existing turbines may be impractical due to costs and downtime, the incorporation of fins during the production of new blades can be very beneficial.
