AIR-CONDUCTING STRUCTURE FOR AN AIRCRAFT, AIR EJECTOR OR EJECTOR PUMP, AND AIRCRAFT

The present invention proposes an air-conducting structure (100) for an aircraft. The air-conducting structure (100) has a first duct portion (110), which is configured to conduct a first air stream (111), a second duct portion (120), which opens into the first duct portion (110) and is configured to conduct a second air stream (121), and a vaned rotor (130), which is arranged in the first duct portion (110) such that it can be driven by means of the second air stream (121). The air-conducting structure (100) can be used as or in an air ejector or ejector pump.
