Abstract:
1. A device for cooling hot gas to be discharged from an aircraft, comprising: a duct for leading the hot gas from a hot gas source which is connectable to the device to an outlet point formed in an aircraft outer skin, a frame which surrounds the duct and serves for mounting the duct, the duct being formed from at least two pipe sections which overlap at their mutually facing pipe ends and having one or more cooling air inlet points which are connectable to one or more cooling air sources in order to mix the hot gas with cooling air, an interspace in the form of an annular gap being formed in at least one region of the duct with overlapping pipe sections between the mutually facing pipe ends, and an outlet pipe section of the duct that extends outwards beyond the aircraft outer skin such that emerging hot gas is led through and outside of a flow boundary layer on the outer skin and mixed in such a manner with the ambient air so that heating up of the outer skin is markedly reduced, including at the outer skin located downstream from the outlet pipe section.
