  • Gas turbine noise suppressor
    Patent number: 4284170
    Abstract: Noise generated in a coannular airstream where there are concentric spaced pipes discharging the flow and the outer pipe extends beyond the inner pipe as in the tail pipe configuration of a fan-jet engine is dissipated by discreetly locating tabs extending internally at the discharge end of the inner pipe. This serves to destroy the coherence of the unsteady pressure field occasioned when the coannular flow streams comingle.
