METHOD FOR DETECTING AN ICING CONDITION OF OR THE NEED FOR SERVICING A FUEL CIRCUIT OF A TURBINE ENGINE
摘要
<p>The invention relates to detecting an icing condition of a fuel circuit (1) of a turbine engine including: a step of acquiring information representative of a first fuel temperature T1 downstream from the fuel metering valve (10) and of the comparison of the first temperature T1 to a first reference temperature Toi; a step of detecting a clogging of the filtration unit (6); and, in the event the measured temperature T1 is lower than the first reference temperature Toi and a clog is detected, transmitting a signal indicating an icing condition of the fuel circuit (1). Information representing a second temperature T2 of the fuel in the tank (3) can be acquired and compared to a reference temperature T02 to confirm or render the icing condition invalid. A signal indicating a need for servicing a fuel circuit is transmitted when the acquired temperatures T1 and T2 are not lower than the reference temperatures Toi and T02 while a clog is detected.</p>
