Abstract
A method and a device for determining, in real time, the flow rate of air collected from an aircraft engine by a system for collecting air from the engine, including an acquisition device for acquiring at successive times measurements of physical quantities in respect of temperature, pressure and pressure loss, specific for the air collection system, a computing device for evaluating at each current time of the successive times a first current estimation of the flow rate of air collected from the aircraft engine on the basis of the physical quantity measurements, the acquisition device for acquiring at the current time a minimum current air flow rate data item defined on the basis of a predetermined flow rate tables, the computing device for hybridising, at the current time, the first current air flow rate estimation and the minimum current air flow rate data item to form a second current air flow rate estimation.
