Abstract

1,132,940. Gas turbine engine combustion equipment. UNITED AIRCRAFT CORP. Oct. 19, 1967 [Nov.25, 1966], No.47705/67. Heading F1L. The invention relates to gas turbine engine combustion equipment of the kind comprising an annular flame tube disposed between inner and outer annular air casing walls, a series of combustion cups each receiving a fuel nozzle, being mounted on one of the flame tube walls adjacent the upstream end thereof, the combustion cups being disposed to form an annular assembly each having axial slidable engagement with the other flame tube wall. The combustion equipment shown comprises an inner air casing wall 6, 10, 16 and an outer air casing wall 8, 12, 23 which define an annular air space including an annular diffuser portion 4, a series of hollow struts 14 extending between the wall portions 6, 8. A pair of spaced-apart nose pieces 40, 46 and a pair of sleeves 36, 56 are located within the diffuser portion 4, the sleeve 36 being formed with notches 38 Fig. 2. to accommodate the strut members 14. The flame tube inner wall 30 is mounted at its upstream end on the downstream end of the sleeve 36 and the downstream end of the flame tube wall is secured be means of a bracket 34 to turbine stator structure including the inner air casing wall 16 and the turbine inlet nozzle guide vane assembly 20, the parts being secured together by means of bolts 22. The outer wall 32 of the flame tube is mounted at its upstream end on the sleeve member 56 and at its downstream end by means of a bracket 62 to the inlet nozzle guide vane structure 28. A series of combustion cups 64 each receiving a fuel nozzle 68 are secured to the flame tube outer wall 32, the cups being in slidable engagement with the flame tube inner wall 30. Each cup 64 is of circular form at its upstream end and diverges at its downstream end to a segment of an annulus. Each cup carries at its upstream end a ring of swirl vanes 66 which engage the fuel nozzle 68. The fuel burner 50 extends through openings in the outer casing 8 and the nose piece 46 and sleeve 56. The inner and outer sleeves 36, 56 are secured together by radial wall members 76, Fig. 2. The flame tube outer wall is located by means of pins 70 which extend into openings in the sleeve 56 and combustion cup 64. The nose pieces 40, 46 are formed with lugs 44, 52 by means of which the pieces are secured to the struts 14.
