Abstract

Official abstract text for this publication.

An aircraft includes a clearance between an opening and a door. The clearance communicates with a cavity and is oriented in a direction intersecting a flow direction of an air flow to the outside of the aircraft in flight. The aircraft further includes an upstream edge and an upstream outer surface situated in front of the clearance joined by a sharp edge with a bend radius of less than or equal to 1 mm, in order to limit the incidence of aerodynamic noise.

First claim

Opening claim text (preview).

1 . An aircraft comprising: an opening; a door configured to close the opening in the closed position; a clearance between said opening and said door when said door is in the closed position, said clearance communicating with a cavity and being oriented in a direction intersecting a flow direction of an air flow to the outside of the aircraft in flight; an upstream outer surface situated in front of the clearance against which the air flow flows; and an upstream edge delimiting the clearance and situated in front of the clearance, wherein the upstream edge and the upstream outer surface are joined by a sharp edge with a bend radius of less than or equal to 1 mm. 2 . The aircraft as claimed in claim 1 , wherein the sharp edge has a bend radius of between 0.5 mm and 1 mm. 3 . The aircraft as claimed in claim 1 , wherein the sharp edge extends over the entire length of the upstream edge. 4 . The aircraft as claimed in claim 1 , wherein the upstream edge is positioned in front of the door in the flow direction of the air flow. 5 . The aircraft as claimed in claim 1 , wherein the door is a door of the passenger cabin.
