Abstract:
1. A propulsion gas exhaust assembly, in an aircraft propelled by hot gases produced along an axis of the aircraft by a gas generator, comprising: a transition element that emerges in first and second duct elements, each of the first and second duct element communicating with a first and second ejection half-nozzle, respectively, wherein each of the first and second duct elements includes an elbow disposed downstream of the transition element, each elbow is defined by a first portion that guides the gas flow in a radial direction away from the axis of the aircraft and a second portion disposed downstream of the first portion, the second portion of each elbow guiding the gas flow in a radial direction toward said axis of the aircraft such that the gas flow downstream of each elbow is returned to the axis, wherein elements disposed inside the duct that are upstream of the elbow are not visible when the assembly is viewed in an upstream direction from a location downstream of the first and second ejection half-nozzles.
