<p>The invention relates to an intermediate housing hub for an aircraft turbofan, including an inner ferrule for defining a first flow space for a main gas flow in a turbofan and moreover at least one intermediate space. The inner ferrule is provided with at least one main opening and at least one movable door forming a main air passage duct. Said door is capable of taking, from the main opening, air flowing into the main gas space and, of sending the air thus taken, back to the intermediate space toward a secondary air passage duct. The secondary duct is moreover extended, from the inlet thereof, by means of a deflector extending upstream into the intermediate space. Said hub is characterized in that the deflector forms an air-guiding duct having an inner surface extending from said inlet to a guide opening arranged downstream from the outlet of the door.</p> |
