Noise from Aft Deck Exhaust Nozzles: Differences in Experimental Embodiments. James E. Bridges. Abstract. Two embodiments of a rectangular nozzle on an aft deck are compared. In one embodiment the lower lip of the nozzle was extended with the sidewalls becoming triangles. Boeing Co patents (2016 archive) Recent patent applications related to Boeing Co. In some embodiments, a disclosed method involves receiving, pairs of image frames, and for a given pair of image frames, determining differences in intensity of corresponding pixels Comparison of Aerodynamic Noise Propagation Techniques (AIAA Noise from Aft Deck Exhaust Nozzles Differences in Experimental In both embodiments the extended deck introduces a new noise source, but the amplitude of the new source was dependent upon the span (cross-stream dimension) of the aft deck. The noise increased with deck length (streamwise dimension), and in the case of the beveled nozzle it increased with increasing aspect ratio. With Noise From Aft Deck. Exhaust Nozzles Differences In.
