Abstract

1361526 Silencing gas turbine engines GENERAL ELECTRIC CO 10 Aug 1972 [16 Sept 1971] 37273/72 Heading F1B A silencer for the exhaust gases from a gas turbine includes a skeletal frame with opposed structural elements 19, 21, Fig.1, and acoustical boxes 35, having lateral spaces therebetween forming gas passageways, each acoustical box having a tunnel member 61 passing therethrough which supports the box on the opposed elements. The exhaust gases pass via the plenum, Fig. 1 and exhaust transition into a lower low frequency section consisting of boxes 35 and a low frequency expansion section 45 and thence via an upper low frequency section and an upper low frequency expansion section to a high frequency section where noise is absorbed by a parallel baffle section 51. Cooling air may be passed through tunnel 61, which is surrounded by fiberglass acoustic and thermal insulation. Boxes 35 have perforated sheet metal sides e.g. stainless steel. The expansion sections 45 consist of a hollow chamber with sheet metal sides insulated on the interior.
