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.

Abstract: The device comprises first means for determining a pressure value relative to the pressure at the outlet of a precooler of an air bleed system and second means for calculating the air bleed level using this pressure value, said first means comprising means for calculating a first pressure value at the outlet of the precooler, using the pressure measured by a sensor, means for receiving a pressure measured by a second sensor, which represents a second pressure value at the outlet of the precooler and means for selecting one of said first and second pressure values, which is then transmitted to said second means for calculating said air bleed level.

Abstract: A system for bleeding air on an aircraft, including: at least one air bleed valve that can bleed a flow of air on the aircraft, a first temperature information module, a second temperature information module, at least one control module, and at least one data processing module coupled to the control module.
