A bypass turbine engine including an inner casing, an inter-duct casing and an outer casing, wherein a primary duct is defined between the inter-duct casing and the inner casing, wherein a secondary duct is defined between the inter-duct casing and the outer casing wherein a rotary shaft includes, at the upstream end, a movable fan including radial blades of which the free ends face the outer casing of the turbine engine so as to compress an air flow at least in the secondary duct, wherein a plurality of variable-pitch radial stator vanes are mounted upstream of the movable fan, the variable-pitch vanes being configured to deflect the incident axial air, wherein the movable fan is configured to axially rectify the air deflected in the secondary duct, and the turbine engine not being provided with stator vanes in the secondary duct downstream of the movable fan.
