See full text

A turbofan engine including a core engine and at least one fan by means of which fluid is guided to a primary flow channel for the core engine as well as to a secondary flow channel of the turbofan engine, wherein the secondary flow channel extends around the core engine, and at least one conduit guided inside a hollow space of a splitter fairing that is arranged in the secondary flow channel. The splitter fairing has at least one overpressure flap with at least one deformable hinge element, with the overpressure flap being flappable as the deformable hinge element is being deformed if a pressure inside the hollow space exceeds a threshold value. Further, at least one opening mechanism is provided by means of which, in the event that the pressure inside the hollow space exceeds a threshold value, a fixation of the overpressure flap is released.
