We let you discover the paper entitled “Fiber Bragg Grating Sensors ice detection: Methodologies and performance” by Miguel González del Val and Malte Frövel from Instituto Nacional de Técnica Aeroespacial (INTA).
The paper addresses the strengths and weaknesses of the Fiber Optic ice Detector (FOD) developed by INTA using a test matrix from the National Research Council Canada / Conseil national de recherches Canada (NRC). The FOD has presented good performance at the NRC ice wind tunnel tests in the ice detection time, detecting ice in most cases earlier than required by the actual standard (ED-103). Its lightness, low intrusiveness and small size, makes the FOD ideal for aeronautical applications. It measures indirectly the icing cloud characteristics, such as the liquid water content (LWC) and the ice accretion rate, so only an approximate severity assessment could be done.
