<p><P>PROBLEM TO BE SOLVED: To provide a bypass turbomachine having a structural intermediate casing 14 between a primary flowpath 2 and a secondary flowpath 3. <P>SOLUTION: A bleed passage 29 allows the diversion of a portion of a gas stream toward the secondary flowpath 3 downstream of a support arm 18 situated at the periphery of the intermediate casing. A bleed opening 28 emerges upstream of the support arm 18. A slide valve 22 slides between three positions, namely, between a closing position in which the slide valve 22 completely blocks off the bleed passage and an opening, an intermediate position in which the bleed opening 28 emerging upstream of the support arm 18 is blocked off, while the bleed passage 29 for diverting a portion the gas stream downstream of the support arm 18 is open, and an opening position in which the bleed opening 28 emerging upstream of the support arm 18 and the bleed passage 29 emerging downstream of the support arm are both open. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
