Abstract

1425438 Gas turbine combustion apparatus GENERAL MOTORS CORP 25 April 1974 [27 Aug 1973] 18142/74 Heading F1L Gas turbine engine combustion apparatus having an annular liner 10 defined by outer, inner and upstream walls 11, 12, 15 respectively includes a flow dividing diffuser 24 extending from the compressor outlet guide vanes 23 and having a passage 36 for diverting a portion of the air directed towards upstream wall 15 into the flow-path 14 adjacent inner wall 12. Air distribution is thus improved during conditions of varying compressor outlet pressure and velocity. Diffuser 24 includes a diffusing passage 40 directed toward diversion passage 36. The proportions of air flowing through the various passages are specified.
