1. An air conduction system for an aircraft engine having an engine axis with a primary flow channel and a branch channel, wherein the branch channel is a secondary flow channel and/or a bleed air channel and wherein the branch channel branches off the primary flow channel at a connecting region, comprising:
a closing device arranged at or in the connecting region for separating the channel from the primary flow channel; the closing device having at least one closing ring for closing the connecting region and an actuator configured and arranged for displacing the closing ring;
wherein the closing ring is displaced by the actuator in an axial direction and in a circumferential direction.
