Turbine rotor assembly
A rotor blade is described for a disk-blade rotor assembly of the axial flow gas turbine engine type having an upstream side and a downstream side and of the type having a cylindrical seal land adapted for opposition to a stator assembly of such an engine, the disk including attachment slots extending across the periphery of the disk from the upstream to the downstream side which adapt the disk to receive the root of the rotor blade and having a lug extending laterally on the disk between each pair of adjacent attachment slots to form a portion of the seal land. The improvement consists of a lug extending laterally from the root of the rotor blade which is adapted to extend between the adjacent lugs and to form an annular portion of the seal land in conjunction with the adjacent disk lugs.
