Latest Patents

One of Dravet's latest patents is a device for reducing noise from jet-pylon interactions on jet engines. This innovative aircraft pylon is designed for mounting dual-flow or triple-flow jet engines. It features an upper surface for connection to the aircraft, two side flanks, and a flange on the lower portion of the pylon. The design includes at least one portion that extends downstream from the cold flow nozzle of the jet engine, lying in the cold flow. Additionally, it has at least one opening positioned on one of the flanks of the pylon, allowing an air stream to be injected into or drawn from the gas flow along the flanks.

Another significant patent is the central body of a turbojet nozzle. This device aims to attenuate acoustical noise from the exhaust nozzle of a turbojet. The turbojet exhaust nozzle includes a central body that defines the inner surface of the primary gas flow path. The central body features an outer wall that defines a single resonator cavity, which is in fluid communication with the primary gas flow path via orifices through at least one upstream portion of the outer wall. This design creates a Helmholtz resonator, effectively reducing noise.
