Short summary
The e-Telltale, a new aerodynamic sensor have been tested in a large wind tunnel in the CSTB. This sensor have been designed to detect the flow separation on wind turbine blades which can cause energy production losses and increased aging of the blades. Theses wind tunnel tests higlighted the good ability of the e-Telltale to detect the flow separation and the influence of the size and location of the e-Telltale on the flow separation detection.

Abstract. The complexity of the flow over a wind turbine blade makes its understanding and monitoring a challenging task, especially on operating wind turbines. The innovative e-Telltale sensor is developed for that purpose : detecting the flow separation on wind turbines blades. In this paper, high Reynolds wind tunnel tests have been performed with different configurations of full scale e-Telltale sensors and wall pressure measurements on a wind turbine blade section. A comparison between the lift curve and the e-Telltale signal was used to evaluate the ability of the sensor to detect flow separation. Results show different interesting properties of the sensor response depending on its size, position along the chord and its fitting process that could be used in real applications.
