Infrared Suppressor Device.
Abstract
This patent application describes an air-cooled contoured plug fitted within the engine tailpipe to physically block any direct view to the turbine section. A vortex cavity is provided around the plug just aft of the plug maximum diameter in order to reduce the length of the cone-shaped plug. The trapped vortex reenergizes the boundary layer built up along the cone surface and allows the flow of hot gases to turn the corner without separating. (Author)
