AIRCRAFT DOOR ARRANGEMENT WITH A NOISE REDUCED HOLLOW SPACE WHICH CAN BE COVERED BY AN AIRCRAFT DOOR

摘要

An aircraft door arrangement (2) for an aircraft fuselage (18) comprises an aircraft door (4), at least one door seal (8) arranged at an inner side of the aircraft door (4) extending circumferentially in an edge region of the aircraft door (4) and a door opening (16) closable by the aircraft door (4) which door opening has an opening edge adjoining to the opening and extending into the aircraft fuselage (18), at which a seal seat (14) is arranged, which can be brought into a flush contact with the door seal (8), wherein a hollow space (22) which is partially covered by the edge region of the aircraft door (4) is formed by the door seal (8), the seal seat (14) and the opening edge. A gap (24) which is located between the aircraft door (4) and the door opening (16) if the aircraft door (4) is closed is connected with the hollow space (22). At least one sound reducing profile (30) is arranged at the opening edge in the hollow space (22), which sound reducing profile comprises a sound reflecting surface (36) which is oriented oblique with respect to a surface of the aircraft door (4) which surface is adjacent to the gap (24), wherein the sound reflecting surface at least partially follows the course of the gap (24).
