Abstract
A propulsion gas exhaust assembly in an aircraft propelled by hot gases produced along an axis of the aircraft by a gas generator is disclosed. The propulsion gas exhaust assembly includes a transition element emerging in two duct elements each communicating with an ejection half-nozzle, wherein each of the two duct elements forms an elbow downstream of the transition element.
Claims18
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.
