  • Patent number: 7819224
    Abstract: An assembly is provided for reducing the noise that is generated in the heating gas zone by turbofan engines. The assembly consists of an acoustically absorbent cladding in the heating gas flow channel of the turbofan engine. The cladding includes a plurality of neighboring cavities, into each of which four horns extends. The mouths of the horns are fixed to a perforated cover sheet. The cover sheet forms one wall of the heating gas flow channel.
    Type: Grant

  • Patent number: 6896219
    Abstract: A process and system for noise reduction in multi-engine propeller-driven aircraft. The parameters of at least two propellers are adjusted with regard to frequency, amplitude, and phase so that the sound fields of the propellers are attenuated or completely extinguished by interference in the area of the closest aircraft fuselage.
