LISI AEROSPACE Predicting the strength of locking devices Every aircraft is fitted with locking systems that perform a variety of functions. They are generally subjected to significant mechanical forces and thus participate in the structural strength of the devices. The means of digital simulation and the research carried out by LISI AEROSPACE in this field make it possible today to predict the mechanical strength of the components of these parts, their rate of deformation and their kinematic behavior. This precious data avoids the prototyping stages and accelerates the testing phases. Gains / Benefit – Save time and reduce costs during development phases. Best time to market. LISI AEROSPACE Big data at the service of quality The production of complex mechanical parts presupposes extremely high quality requirements. This is the case for the leading edges manufactured at the Marmande site and which require controlling all the manufacturing data that influence the final result. The Product & Process teams have thus identified nearly 30,000 relevant parameters to record, monitor and correlate. The automatic recording of this data allows each part produced to have its own genome. Analyzed in real time by software adapted to the processing of big data, this data makes it possible to measure possible drifts on a product feature and to identify the manufacturing parameters it stems from. Their accumulation finally makes it possible to capitalize on incomparable knowledge and to feed the simulation models of manufacturing processes. Gains / Benefit – These databases constitute a competitive edge. They allow for continuous improvement of quality and manufacturing costs. The Product & Process teams have identified nearly 30,000 relevant parameters to record, monitor and correlate to control the manufacturing data that influence the final result. 41 LISI 2019
