METHOD AND DEVICE FOR MONITORING A LUBRICATION SYSTEM

摘要

According to a first aspect, the invention relates to a method for monitoring a lubrication system (1). The method comprises the steps of: providing at least one temporal evolution of at least one input data (210); providing a model (310) of said lubrication system (1) comprising parameters; generating diagnostic output data (220) of said lubrication system (1). The step of generating diagnostic output data (220) of the lubrication system (1) comprises the following steps: generating a temporal evolution of a residual (200) from said at least one temporal evolution of said at least one input data (210) and from said model (310); generating said diagnostic output data (220) by using a decision method (140) applied to said residual (200) and accounting for said temporal evolution of said residual. The method is characterized in that the model (310) includes a unique gulping effect for any flight conditions of the aircraft.
