    摘要: 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.

    摘要: Vortex generators are arranged on the edges of aircraft wing control surfaces to generate smaller vortices that weaken the main vortex that would otherwise be generated at these areas, and thereby reduce the aerodynamic generation of noise. Each vortex generator includes plural elongated elements in the form of rigid rods or flexible bristles protruding laterally outwardly from the respective edge of the control surface. The vortex generators are preferably arranged on the inboard and outboard edges of high lift flaps and slats.
