Abstract

694,448. Generating combustion products under pressure. ROLLS-ROYCE, Ltd. Jan. 7, 1952 [Oct. 9, 1950], No. 24656/50. Class 51(i) In an air jacketed type of combustion chamber for a gas turbine engine, the air flow is divided into two parts, one of which enters the flame tube at its inlet end and the other of which flows around the outside of the flame tube, by means of a duct part which is supported from the air casing by one or more supports, the duct part affording at its outlet end a support for the inlet end of the flame tube. A fuel burner or nozzle is supported from the air casing by a strut which extends through an aperture or cut-away in the duct part, and has a shaped flanged portion in the cut-away so as to afford a continuation of the wall of the duct part, the fuel nozzle and support being removable from the air casing without removal of the duct part. The duct part 11 in Fig. 1 has struts 13 formed integrally therewith which are secured in recesses 14 in the air casing wall 10a by studs 15, and the duct part has a cut-away 22 extending from the leading edge 11a. The support strut 26 for the fuel nozzle 29 has a base portion 25, by which it is supported on the air casing 10b, and a flange 30 the slope of which corresponds to the cut-away 22. Ducts 31 are formed in the fuel nozzle support. In Fig. 4, the duct part 11 is formed with lands 35, 36, 37 which are connected to lands 38, 40, 41 formed on the air casing walls 10a, 10b, and comprises a frusto-conical part and an inner cylindrical part 11b. Apertures 45, 44 are formed respectively in the duct part and air casing. The support for the fuel nozzle 51 comprises a base portion 47 connected to the air casing and a strut 49 having flange portions 52, 53 corresponding to the shapes of the apertures in the frusto-conical part and the cylindrical wall 11b of the duct part. The fuel nozzle and support may be removed by movement first forwardly then radially outwardly. Specification 686,383 is referred to.
