Abstract
713,422. Generating combustion products under pressure. ROLLS-ROYCE, Ltd. June 4, 1951 [March 28, 1950], No. 7794/50. Class 51 (1) In an air jacketed type of combustion chamber for a gas turbine engine, primary air is introduced into the flame tube through a duct at the upstream end thereof, the duct terminating within the flame tube, being of cylindrical or frusto-conical form, lying on the axis of the flame tube and including swirl vanes. The duct is so dimensioned that the ratio of the length L thereof on the downstream side of the swirl vanes to the diameter of the duct is greater than unity. The diameter of the duct is defined as the internal diameter of the wall of a full cylindrical duct, the internal diameter of the outer wall of an annular duct, the mean diameter of the wall of a converging or diverging duct or the mean diameter of the outer wall of a converging or diverging annular duct. The combustion chamber has a fuel injector 11 which lies on the axis of the flame tube, the injector being surrounded by the tubular portion 8a of the flame tube wall 8 so as to constitute an annular duct 15 in which the swirl vanes 16 are mounted. The wall 7 of the flame tube is supported on a seating 20 formed on a conical duct part 21 which is supported within the combustion chamber casing by aerofoil section supports 12. The body of the fuel atomizing injector is mounted on an extension 12a of the supports 12 through which extend fuel passages 13, 14. The wall members 7, 8 may be perforated to allow a small air-flow therethrough to reduce the tendency of carbon formation. Specification 686,383 is referred to.
