Abstract
A differential pressure transducer provides measurements for determining the restriction, updated in real time, of an inlet barrier filter for a turboshaft engine of an aircraft. The percentage of restriction of the air inlet barrier filter, which corresponds to the condition of the air inlet barrier filter, is determined as a function of mass air flow into the engine during operation. The restriction percentage is indicated on the instrument panel of the rotorcraft.
