Abstract

Turbomachine (10) d’aéronef, comportant : - une enceinte annulaire (Z) de circulation d’air de ventilation, cette enceinte s’étendant autour d’un axe principal (A) de la turbomachine et comportant au moins une entrée d’air (80) et au moins une sortie d’air (82), - une machine électrique (70) de forme annulaire s’étendant autour de l’axe principal (A) de la turbomachine, à l’intérieur de l’enceinte (Z), et comportant un rotor (70a) et un stator (70b) coaxiaux qui définissent entre eux un entrefer annulaire (84) de passage d’un premier flux d’air (F2) de ventilation, caractérisée en ce qu’elle comprend en outre un piège magnétique (100) à particules métalliques, ce piège étant situé dans ladite enceinte (Z) et étant configuré pour attirer et retenir les particules métalliques contenues dans ledit premier flux d’air (F2). Figure pour l'abrégé : Figure 5Aircraft turbomachine (10), comprising: - an annular enclosure (Z) for the circulation of ventilation air, this enclosure extending around a main axis (A) of the turbomachine and comprising at least one air inlet air (80) and at least one air outlet (82), - an electrical machine (70) of annular shape extending around the main axis (A) of the turbomachine, inside the enclosure (Z), and comprising a coaxial rotor (70a) and stator (70b) which define between them an annular air gap (84) for the passage of a first flow of ventilation air (F2), characterized in that it further comprises a magnetic trap (100) for metal particles, this trap being located in said enclosure (Z) and being configured to attract and retain the metal particles contained in said first air flow (F2).
