Patent ID: 8172178

Claim:
An aircraft with an outer surface from which flows an aerodynamic stream of cold air, comprising: at least one hot gas outlet; and at least one device ( 16 ) for generating aerodynamic disturbances connected to the outer surface ( 10 ) upstream from a hot gas outlet ( 12 ), wherein said at least one device ( 16 ) for generating aerodynamic disturbances and said at least one hot gas outlet ( 12 ) are aligned in a flow direction of the aerodynamic stream so as said at least one device ( 16 ) generates disturbances at a level of the aerodynamic stream of cold air upstream from the outlet ( 12 ) that contributes to mixing of the hot gas evacuated through the outlet ( 12 ) with the colder air of the aerodynamic stream, wherein a distance that separates the device ( 16 ) for generating the disturbances and the hot gas outlet ( 12 ) is on the order of 10H, whereby H is a height of said device.
