ABSTRACT:
A modified exhaust tailpipe especially for use with an aircraft turbofan engine utilizing a noise suppressor. The modified tailpipe is connected to the exhaust duct of the engine. The forward end of the tailpipe is essentially the same diameter as that of the exhaust duct of the engine. The contour of the tailpipe is such that it increases in diameter to form a bulge to increase the flow area for fan gases in the area of a mixer which is supported within the forward end of the tailpipe exhaust system. This improves the operating efficiency of the jet engine.
