Wind turbine blades are constantly submitted to different types of particles such as dirt, ice, etc., as well as all the different environmental parameters that affect the behaviour and efficiency of the energy generation system. These parameters can cause faults to the wind turbine blades, modifying their behaviour due, for example, to the turbulence. A new method is presented in this paper based on cross-correlations to determine the presence of delamination in the blades. The experiments were conducted in two real wind turbine blades to analyse the fault and non-fault blades using ultrasonic guided waves. Finally, the energy analysis of the signal based on wavelet transforms allowed to determine energies abrupt changes in the correlation of the signals and to locate the faults.

One of the most demanded assets nowadays is energy. Over many options to generate it, humankind must seek sustainable ways; therefore, renewable energies must be empowered. Moreover, wind provides great benefits, granting uncalculated power at our disposition. Since this task is executed by big structures, their maintenance represents a difficult task for human efforts to achieve, because the height requires much support, effort and time to accomplish. A Remotely Piloted Aircraft System (RPAS) can be adapted to perform surveillance on different types of surfaces, presenting a comfortable way to execute it in dangerous and difficult to access spaces, providing safer methods, and bringing experience of qualified workers and technology together. This paper will provide methods for generating a trajectory over Wind Turbine blades, relying on the specification of a Phantom 4. The main objective is to establish a path over this structure, based on the measurements of a specific model and incorporating all of the blades surface. The results were satisfying once the precision was inside the allowed deviation. Nevertheless, some issues might be improved such as the velocity between waypoints and the polynomial selected to define the trajectory.
