We have studied the three dimensional, unsteady, flows around a wing in various flight conditions, mimicking those experienced during take-off and landing or the influence of a wind gust. With the aid of numerical simulations, as an alternative to experiments in wind tunnel, we were able to develop new wing designs that can enhance aerodynamic performance at no extra cost. These can improve an aircraft’s maneuverability, increase the amount of weight it can carry, or reduce the fuel consumed – all of which may contribute to reductions in greenhouse gases.
