Title (EN) A BLADE DEFLECTION MONITORING SYSTEM
(FR) SYSTÈME DE SURVEILLANCE DE FLÉCHISSEMENT DE PALE
Abstract:
(EN) A wind turbine blade comprising a system for monitoring the deflection of a wind turbine blade is described. The system comprises a wireless range-measurement system, having at least one wireless communication device located towards the root end of the blade and at least one wireless communication device located towards the tip end of the blade, the communication devices comprising antennas polarized substantially perpendicular to the suction side of the blade and substantially parallel to the leading edge of the wind turbine blade.
(FR) L'invention concerne une pale d'éolienne qui comprend un système permettant de surveiller le fléchissement d'une pale d'éolienne. Le système comprend un système de mesure de distance sans fil, ayant au moins un dispositif de communication sans fil situé vers l'extrémité d'emplanture de la pale et au moins un dispositif de communication sans fil situé vers l'extrémité bout de la pale, les dispositifs de communication comprenant des antennes polarisées sensiblement perpendiculairement à l'extrados de la pale et sensiblement parallèlement au bord d'attaque de la pale d'éolienne.
