Aeronautic Data Analysis Use Case in Safran Aircraft Engines (Application of doctoral research for new turbofan programs.)
By Jérôme Lacaille, Expert in algorithms, Safran Aircraft Engines
By analysing the data emitted by engines in operation, we can see that their behaviour evolves over time. Our challenge is to extract the internal state of each engine, free from the operational context of the aircraft. To do this, we need to model the missions to decontextualize the data, and also create a temporal representation of the impact of successive flights.
The flight context is defined by both pilot commands and aircraft trajectory. Engine status can be determined from measurements provided by sensors installed on the engines, whose data, pre-processed by the on-board computer, is transmitted to the ground. This data comes in two forms: snapshots captured during specific phases of the flight and transmitted in real time by satellite, or continuous data downloaded when the aircraft lands at one of the airline's hubs.
Our intervention is part of a continuing effort to create a digital twin for each engine manufactured by SAFRAN AIRCRAFT ENGINES, in the form of a simulator. This simulator will enable us not only to compare the engines with each other by observing their performance during virtual test flights, but also to classify the different states of wear identified.

Biography : Jérôme Lacaille is a former student of the École Normale Supérieure and holds a teaching qualification in mathematics. He served as a lecturer at the École Normale Supérieure before co-founding the startup MIRIAD Technology, specializing in aeronautics. His professional journey led him to the semiconductor industry, where he was recruited as an expert by SNECMA (now Safran Aircraft Engines) in 2007. At Safran, he established the DataLab in 2015, overseeing a team of PhD students and currently leading the company's mathematical network.
In addition to his corporate responsibilities, Jérôme serves as an associate professor at Université Sorbonne Paris Nord and École Normale Supérieure de Paris-Saclay. He is also a member of the scientific council of the Agence pour les mathématiques pour l'industrie et la société (AMIES) and previously held the position of vice-president at the Société de mathématiques appliquées et industrielles (SMAI). |
