Abstract

949,231. Compressor blades; gas turbine plant; axial flow compressors. ROLLS-ROYCE Ltd. April 27, 1962 [May 3, 1961], No. 16090/61. Headings F1C, F1G and FIT. A gas turbine engine has a compressor provided with a ring of angularly spaced apart inlet guide vanes, the radially inner and/or the radially outer ends of the vanes having their upstream and downstream sides mounted in angularly spaced apart slots in a pair of axially spaced slotted annular members. The radially outer ends 23 of the inlet guide vanes 14 of a gas turbine engine are bonded in slots 24, 25 of annular members 26, 27 which are bonded to the casing member 21, the latter having apertures through which the vanes 14 pass. The member 27 is bonded and connected by locating peg 30 to member 31 which is then bonded to casing member 22. Members 26, 27, 31 are bonded to an outer casing member 32. The radially inner ends 33 of the vanes 14 are bonded within slots 34, 35 of annular members 36, 37, member 36 consituting the end wall of a U-section ring 40 having radially outer and inner walls 41, 42. Roots 33 pass through apertures in the wall 41. An inner hub member 44 is bonded to ring 40 and bearing housing 45 is bonded to member 44. Outer race 47 of thrust bearing 46 is splined within housing 45 and retained in position by spring 50. An annular sealing plate 51 carries a labyrinth seal 52. The guide vanes, annular and casing members are formed of reinforced synthetic resin material such as epoxy or phenolic resin reinforced with glass fibres.
