Abstract

1,049,080. Gas turbine engine stator vane mounting. GENERAL ELECTRIC CO. Nov. 16, 1964 [Dec. 2, 1963], No. 46579/64. Heading F1T. A gas turbine engine has turbine stator guide vanes 36 pivotally mounted between radially outer and inner walls 11, 37 and moved by links 55 attached to an annular control ring. Circular shroud platforms 50 are secured to both ends of the vanes and are received in recesses 52, 53 in walls 11, 37 respectively. Platforms 50 are adjacent the trailing edges of vanes 36 so as to reduce leakage in the region where the pressure gradient between the concave and convex side walls 40, 41, respectively, Fig. 4 (not shown), of the vanes is the greatest. The circumferential spacing (S) between adjacent vanes 36 is less than the chord width (C) and the platform diameter (d) is less than S. The invention is applicable also to a gas turbine engine compressor, in which case the circular platforms are positioned with their centres between 40 and 50 per cent of the chord width from the vane leading edge, i.e. where the pressure gradient is the greatest, Fig. 6 (not shown).
