A hush kit for jet aircraft engine includes a respaced inlet guide vane to provide an increased space between the fixed guide vanes of the inlet and the rotating fan blades of the fan connected to the core engine, a mixer for mixing hot exhaust gas from the core engine with colder bypass fan air, and an acoustic barrel to reduce the noise generated by the mixed air flowing through the thrust reverser downstream of the core engine. The acoustic barrel includes an outer imperforate layer, an inner perforate layer and a multi-cellular core sandwiched thereb...
A noise reduction assembly for a jet engine having a core engine generating axial exhaust gas flow through a downstream end thereof, an inlet having a plurality of fixed guide vanes at an upstream end of the core engine, an outer casing defining an annular bypass duct surrounding the core engine, a fan positioned downstream from the inlet for generating axial fan air flow through the bypass duct, a thrust reverser for selectively converting axial flow of exhaust gas and fan air into reverse thrust, and a tail pipe disposed to axially receive and discharg...
