Title (EN) AEROSPACE TRANSPARENCY HAVING MOISTURE SENSORS
(FR) VITRAGE D'AÉRONEF COMPRENANT DES CAPTEURS D'HUMIDITÉ
Abstract:
(EN) A transparency, e.g. an aircraft laminated windshield, includes one or more moisture sensors to monitor moisture penetration to monitor performance of the moisture barrier. At least one of the moisture sensors includes an electrolyte between and in ionic contact with two electrically conductive electrodes. Measuring the potential between the first and second electrode and/or the current through the electrodes to determine the amount of moisture within the laminated windshield in the area of the moisture sensor. With the information provided by the moisture sensors performance of the windshield is available to schedule timely repair or replacement of the windshield that is performing outside of acceptable limits.
(FR) La présente invention a trait à un vitrage, tel qu'un pare-brise stratifié d'avion, qui comporte un ou plusieurs détecteurs d'humidité conçus pour contrôler la pénétration de l'humidité afin de contrôler les performances de la barrière contre l'humidité. Au moins l'un des capteurs d'humidité comprend un électrolyte entre deux électrodes électriquement conductrices et en contact ionique avec celles-ci. On mesure le potentiel entre les première et seconde électrodes et/ou le courant à travers les électrodes pour déterminer la quantité d'humidité à l'intérieur du pare-brise stratifié dans la zone du capteur d'humidité. Grâce aux informations fournies par les détecteurs d'humidité, les performances du pare-brise permettent de prévoir la réparation ou le remplacement opportuns dudit pare-brise lorsque ses caractéristiques d'utilisation sont hors des limites acceptables.
