UNION DE PALA SENSORIZADA.

摘要

A wind turbine blade is subdivided transversely into two or more sections (10,11) joined together at blade joints (12) including mechanical joining elements (9) between blade sections, that include a number of sensors (14,15,5), preferably load cells and ultrasound sensors, assembled into the mechanical joining elements between blade sections. Their measurements allow the loads to be reduced and the forces to be controlled during the entire life of the blade. They also allow damages to be detected (stopping the machine if necessary) and an optimised design for real loads.
