Abstract
Dispositif pour éjecter, en amortissant son énergie cinétique, un fragment d'aube rompue de machine tournante axiale en vue d'éviter la perforation du carter de la machine et la rupture des aubes voisines. Le dispositif est constitué par une rampe hélicoïdale en relief portée par la paroi interne du carter de la machine, le sens du pas de l'hélice étant opposé au sens de rotation des aubes. Aéronautique : soufflantes de turboréacteurs.
