Abstract
The bypass turbomachine comprises, between a primary flowpath () and a secondary flowpath (), a structural intermediate casing (). A bleed passage () allows the diversion of a portion of the gas stream toward the secondary flowpath (), downstream of support arms () situated at the periphery of the intermediate casing. A bleed opening () emerges upstream of the support arms (). A slide valve () slides between three positions, namely a closed position in which the slide valve () completely blocks off the bleed passage and opening, an intermediate position in which the bleed opening () emerging upstream of the support arms () is blocked off, while the bleed passage () for diverting a portion of the gas stream downstream of the support arms () is open, and an open position in which the bleed opening () emerging upstream of the support arms () and the bleed passage () emerging downstream of the support arms are both open.
