Abstract
A propulsion system assembly for a vehicle such as an aircraft having a nacelle and shroud is disclosed. Various construction details are developed which permit the flow of cooling air into the full circumference of the shroud despite the blockage of the shroud by upstream structure such as a pylon on an aircraft engine. In one embodiment, the nozzle is disposed downstream of an engine in the nacelle and inwardly of the shroud. A passage 44 extends rearwardly in the pylon and underneath the shroud to duct cooling air into regions of the shroud blocked by the upstream structure.
