1275970 Gas turbine stator vanes ROLLS ROYCE Ltd 15 Oct 1970 [27 Oct 1969] 52558/69 Headings F1G and FIT In a gas turbine engine the turbine nozzle guide vanes 22 or interstage guide vanes 23 have variations in circumferential spacing to compensate for circumferential variations in the gas flow temperature. The flow areas 36 at the inlet to vanes 23 differ from areas 37 which in turn differ from areas 39, although all outlet areas 38 are equal. The shape or angle of attack of the vanes may also vary. The construction reduces circumferential pressure variations in annular spaces such as C.
