Abstract
An acoustic noise elimination assembly having a capability for disrupting the continuity of fields of sound pressures forwardly projected from fans or rotors of a type commonly found in the fan or compressor first stage for air-breathing engines, when operating at tip speeds in the supersonic range. The assembly incudes a tubular cowl 12 defining a duct for delivering an airstream axially into the intake for a jet engine E and a sound barrier 14, defined by a plurality of intersecting flat plates or struts 14a-14d having a line of intersection coincident with a longitudinal axis of the tubular cowl, which serves to disrupt the continuity of rotating fields of multiple pure tonal components of noise.
