DEVICE FOR REDUCING NOISE FROM JET-PYLON INTERACTIONS ON JET ENGINES

摘要

Aircraft pylon for supporting a turbojet engine (1) with double or triple flow, comprising an upper face of connection to the aircraft, two lateral flanks and a sole at its lower part, said pylon comprising at least one part extending downstream of the nozzle (5) of the cold stream of said turbojet engine and immersed in the cold stream, characterized in that it comprises on its part extending in the cold stream beyond said nozzle at least one orifice ( 8) positioned on one of the sides of said pylon, through which an air jet is injected into, or sucked in from, the gaseous flow flowing along its flanks to limit the turbulent flow of the gaseous flow flowing along said flanks of said pylon, sources of noise, by decorrelating said flows of said flanks of said pylon with said air jet.
