  • Noise suppressing mixer for jet engines
    Patent number: 6276127
    Abstract: The mixer has a circular forward end which is attached to the exit of a jet engine, or the core of a bypass engine. The mixer has radial lobes which increase in their radial dimension with increasing distance aft of the forward end. There are corrugations, termed circumferential lobes, in the after portions of the walls of the radial lobes. These circumferential lobes increase the ratios of wetted areas to cross sectional areas of the passageways through the mixer. Also, the dimensions of these lobes are small relative to the radius of the mixer.
