Patent number: 11155360Abstract: A method for monitoring at least one engine of an aircraft wherein the aircraft includes a passenger cabin. The method includes a step of acquiring a signal that is at least in part representative of the activity of the engine, using a sensor during a flight of the aircraft, and searching for a defect in the engine by a processing unit using data obtained from the signal. In some embodiments, the sensor is in a mobile device located in the passenger cabin. In some embodiments, the health of the at least one engine uses the signal acquired by a plurality of mobile devices.Type: GrantFiled: March 15, 2018Date of Patent: October 26, 2021Assignee: SAFRAN AIRCRAFT ENGINESInventors: François Prost, William Bense, Serge Blanchard

Patent number: 10174863Abstract: A method and a system are provided for detecting first signs of failure in an aircraft engine valve. The system includes an acquisition device configured to acquire output pressure measurements of the valve and command and context data related to the valve, and a processing device configured to define a set of indicators of first signs of failure as a function of the output pressure measurements and the command and context data. The processing device is configured to monitor a change over time in each indicator of the set of indicators of first signs of failure. The processing device is configured to detect a possible deviation of at least one indicator among the set of indicators, the deviation representing the first signs of failure of the valve.Type: GrantFiled: August 4, 2014Date of Patent: January 8, 2019Assignee: SAFRAN AIRCRAFT ENGINESInventor: William Bense
