Partners : SAFRAN

Researchers : L. Piscini (PHD Students), D. Matt (Professor),

Duration : 3 years (2017-2020)


One of the main lines of research of the aerospace industry is hybrid propulsion. The program, which aims to drastically reduce the emissions produced by today's aircraft, aims to identify the concepts of aeronautical hybrid propulsion systems likely to be available in the years 2030-2035 [Nasa]. Due to this growing electrification of the transport industry, a gradual increase in the mass and volume compactness of electromechanical converters is required. SAFRAN TECH, Safran group entity which aims to conduct research projects called 'low' TRL 1-4 (Technical Readiness Level), or R & T, of interest to companies of the SAFRAN group, is a carrier of innovation and funds various research projects of which this thesis work is a part. In this perspective, the latest contributions made by the collaboration between Safran group companies and the IES laboratory have shown very encouraging results in increasing compactness, while controlling additional losses. This multidisciplinary study must contribute to the minimization of the volumes / masses of the magnetic circuits constituting the electric machine, while controlling the associated losses in order to respond to an aeronautical application specified by the company. In one part of the project, test bench tests will validate the design.

Cette étude, pluridisciplinaire, doit permettre à son tour de contribuer à la minimisation des volumes/masses des circuits magnétiques constituant la machine électrique, tout en maitrisant les pertes associées afin de répondre à une application aéronautique spécifiée par l'entreprise. Dans une partie du projet, des tests sur banc d'essais viendront valider le dimensionnement.
