Abstract

L'invention concerne les dispositifs de retenue des pales arrachées des soufflantes. Elle se rapporte à un dispositif dans lequel un anneau 34 de retenue est placé autour des extrémités des pales 12 d'une soufflante, et est maintenu à distance d'une paroi externe 56 délimitant le conduit de circulation des gaz et du bâti de la machine par des entretoises 58 et 60. Lorsqu'une pale 12 est libérée ou vient frotter, les entretoises 58 et 60 peuvent s'affaisser et l'énergie de rotation des pales est encaissée par la rotation de l'anneau 34. Application aux moteurs à turbine à gaz.
