Abstract

786,088. Gas turbine jet propulsion plant. NAPIER & SON, Ltd., D. March 13, 1956 [March 30, 1955], No. 9321/55. Class 110 (3). [Also in Group XXVIII] An exhaust duct assembly for a gas turbine engine leading to an outlet orifice or nozzle comprises an annular diffusing duct extending from the annular turbine outlet and disposed coaxial therewith which terminates in two similar volute ducts which extend in opposite circumferential directions from a substantially radial dividing edge facing the gas flow located at one diametric side of the axis of the diffuser to a common delivery duct extending from the opposite diametric side of the axis of the diffuser in a direction having a substantial radial component to that axis and leading to or terminating in an outlet orifice or nozzle. The turbine casing A, Fig. 1, is supported from the bulkhead B by a tubular engine mounting B<SP>1</SP>. The exhaust duct assembly is attached to the turbine casing at C and comprises an annular diffusing duct D which discharges into a casing E having two volute ducts El, E<SP>2</SP>, Fig. 2, extending in opposite directions from a dividing edge E<SP>3</SP> to a common delivery duct F which is divided initially by a partition E<SP>4</SP>. The duct F comprises an upper section F<SP>1</SP>, an intermediate section F<SP>2</SP>, and a lower section F<SP>3</SP> connected together by expansion joints. The lower section F<SP>3</SP> is curved and terminates in a nozzle F<SP>4</SP>. The section F<SP>3</SP> is connected by one or more struts B<SP>2</SP> to a bracket B<SP>3</SP> rigid with the turbine casing A. The expansion joint G, Figs. 1 and 8, comprises flange members G<SP>1</SP>, G<SP>3</SP> which co-operate with one another by a piston ring type seal G4 and are held in relation to one another by a flexible tension member or wire J which passes in zig-zag manner through slots in lugs G<SP>7</SP> attached to the flange members. One of the flange members may be adjustable with respect to its duct so that a predetermined degree of tension can be applied to the duct and hence to the flexible members associated with the expansion joint. The duct section F<SP>3</SP> may be directly connected to the turbine unit supporting structure.
