Device and method for bleeding compressor air in a turbofan engine

A device for bleeding compressor air in a turbofan engine, comprising:

• a low-pressure compressor of a primary flow duct of the turbofan engine,
• a fan stator arranged in a secondary flow duct of the turbofan engine downstream of a fan in the flow direction, and
• an arrangement by means of which compressor air to be discharged from the low-pressure compressor is introducible into the secondary flow duct,
• with the arrangement including air guiding devices such that the compressor air is guided into the secondary flow duct upstream of the fan stator relative to the flow direction in the secondary flow duct, is there guided past the stator vanes of the fan stator in a separate flow duct in the axial direction and is only mixed with the air of the secondary flow duct downstream of the fan stator, and with
• the separate flow duct being formed by a plurality of hollow structures extending in the longitudinal direction each between two adjacent stator vanes of the fan stator, with the hollow structures having a closed circumference in cross-section.
