Abstract
1472570 Gas turbine blades rotor-cooling GENERAL ELECTRIC CO 19 July 1974 [2 Aug 1973] 32125/74 Headings F1G and F1T The invention relates to a gas turbine bladed rotor assembly in which means are provided for supplying liquid coolant on to the rim of the rotor disc for flow through passages extending through the blades. The rotor disc is formed at its periphery 12 with axial slots 11 in which the blades 10 are mounted by their roots. A ring member 13 is secured at each side of the rotor disc for example by shrinking to retain the blades in position, each ring member being formed with an annular recess 16 into which liquid coolant is supplied through a nozzle 14. The coolant passes from the recess through a plurality of openings 17 into a recess 18 formed at the underside of each blade platform 19. The liquid then passes over the lip 22 to a further recess 23 from which it discharges through passages 26 and then through passages 27 extending through the aerofoil portion 29. The coolant collects in a manifold recess 31 at the blade tip from which it discharges through outlet 33; a similar flow of coolant is provided for at each blade face, the two flows discharging through a common outlet 33.
