Sound attenuating laminate and installation for jet aircraft engines

摘要: The present invention relates to a novel sound attenuating laminate and installation method. More particularly, the simpler, lighter, more effective noise which is made up of seven layers material. includes duct liner (12), moisture barrier (14), first protecting layer (16), screen (18), acoustic material (20), second (22), solid backing sheet (24). readily incorporated into various sections jet engine compartment (30) in order attenuate produced by engine. Hollow rivets (58), (59) are used conduct acoustical energy intermediary laminate. This means for conducting also allows an improved anti-icing system, efficient operation, dissipation energy.
