초록

Retractable multiple aperture arrays, mounted behind jet engines that produce jet exhausts that pass chordwise over the wings of an aircraft, are disclosed. In their operative positions, a multiple aperture array lies in the exhaust path of each engine, immediately rearwardly of the engine nacelle. In this position, in a conventional manner, the arrays split the exhausts into separate streams, which entrain ambient air. The entrained ambient air mixes with the separated streams in the region where the streams recombine to suppress engine exhaust noise an...

청구항

In a jet aircraft including wings and jet engines mounted such that the exhausts of said jet engines pass chordwise over said wings and create noise sources having centers located beyond the trailing edge of said wings, the improvement comprising a plurality of multiple aperture arrays, one of said multiple aperture arrays being associated with each of said jet engines of said aircraft, each of said multiple aperture arrays being movable between a stowed position whereat said multiple aperture array lies outside of the exhaust path of the jet engine with...
