Abstract
A propulsion system assembly includes a core flowpath, a bypass flowpath, a flowpath wall, an ejector body and an air circuit. The bypass flowpath is radially outboard of the core flowpath. The flowpath wall forms an inner peripheral boundary of the bypass flowpath. The flowpath wall extends axially along and circumferentially about an axis. The ejector body is disposed in the bypass flowpath. The ejector body is spaced radially outboard from the flowpath wall by a first distance such that a portion of the flowpath radially between the ejector body and the flowpath wall forms an ejector passage. The ejector passage extends axially along the axis from a passage inlet to a passage outlet. The air circuit extends from a circuit inlet to a circuit outlet. The circuit inlet is fluidly coupled to the core flowpath. The circuit outlet is fluidly coupled to the bypass flowpath at the passage outlet.
