Aircraft jet pod for military aeronautical application, has jack with fixed part or body displacing downstream part of wall to vary section of flow outlet passage, and fluidic device forcing leakage flow along outer side of part of wall

摘要

The pod (12) has a wall (24) surrounding a jet (16) and defining an annular inner fluid flow duct (26) that has a flow outlet passage. A jack has a fixed part or a body that displaces a downstream part (24b) of the wall, on control, to vary a section of the flow outlet passage by which a major part of flow (Fi') escapes. The displacement creates an opening through which a less part of a leakage flow (Fi'') escapes naturally. A fluidic device (30) forces the leakage flow to be flown along an outer side of the part of the wall situated in upstream of the opening.
