SUPPORT PYLONE OF A TURBOMOTOR COVERED WITH POROUS MATERIAL, COMPRISING A TURBOMOTEUR AND A PYLONE

摘要

A pylon (2) for supporting a turbine engine (1) on an aircraft whose outer surface is at least partially covered with a porous material arranged to reduce the amplitude of acoustic waves at the output of the turbine engine (1). An assembly of a turbine engine (1) and a pylon (2), the pylon (2) extending longitudinally from upstream to downstream and comprising an upper fixing part (21) to the aircraft, a part of lower attachment (22) to the turbine engine (1) and an absorption part (23) extending in the ejection flow of the turbine engine (1), comprising an internal absorption part (26), extending into the turbine engine (1), and an external absorption part (24), extending downstream of the turbine engine (1), pylon in which the outer surface of the upstream end (25) of the external absorption part ( 24) is covered by a porous material so as to limit the formation of noise downstream of the engine.
