Abstract
The invention relates to a bypass turbomachine () for an aircraft, comprising a gas generator () and a ducted fan () comprising variable pitch blades () configured to take a reverse thrust position driving a reverse flow () of air within a secondary duct (), the gas generator () being connected to a fan casing () by a stator blade assembly () that passes through the secondary duct, first openings () for letting in air from the reverse flow being located on an outer casing () at least partially internally delimiting the outer duct, and second openings () for letting said air out being located on an inner casing () at least partially externally delimiting an inner duct (). The first openings are located within a plane that is perpendicular to a longitudinal axis (C) of the turbomachine and passes substantially through the middle of the blade assembly.
