Abstract: 1276777 Cooling gas turbine engines GENERAL MOTORS CORP 19 Nov 1970 [25 Nov 1969] 55057/70 Headings F1G and FIT The turbine of a gas turbine engine is cooled by directing thereto from the engine compressor two supplies of cooling air in varying relative quantities, one of the supplies being heated to a temperature higher than that of the other supply. In one arrangement a first supply of cooling air is directed from the engine compressor through conduits 27' to a manifold 43 radially inwards of the inner shroud 15' of adjustable turbine stator vanes 13. A second supply of cooling air is directed through conduits 28' disposed adjacent flame tube 7 so that the air is heated by heat exchange with the combustion gases before entering a manifold 44. Shroud 15' has circumferentially staggered air inlets 54, 55 adjacent respectively manifolds 43, 44 and co-operating with mixer valve members 52 integral with arms 48 fixed to the shafts 47 of vanes 13. Thus as unison ring 17 adjusts vanes 13 valve members 52 move to vary the relative proportions of cooler and warmer cooling air flowing through inlets 54, 55 respectively into the interior of shroud 15'. The mixed cooling air flows through the interior of vane shafts 47 into vanes 13 and thence escapes through pores in the walls thereof. Some cooling air may flow through holes in the downstream wall of shroud 15', into the rim portion of turbine rotor 20 and thence into blades 19. In a modification, Fig. 1 (not shown) valve members 52 are replaced by push-rod operated slide valves (35) at the upstream ends of conduits (27, 28) corresponding to conduits 27', 28'. Both embodiments are arranged such that as turbine temperature increases cooling is effected initially by the warmer air from conduits 28' (or 28), then by a varying mixture and finally by the cooler air from conduits 27' (or 27).
