Abstract
A turbine has a rotor which is a disc with blades projecting axially from its face working with stator blades on a disc like stator. Such discs and blades can be cast integrally and if necessary machined flat for good sealing. A plurality of interdigitated stator and rotor discs can be assembled. The rotor can be made of sintered or refractory material and bonded by a hoop of high tensile material to take centrifugal forces enabling low tensile strength material to be used for rotor parts.

A method of making a turbine having a plurality of interdigitated discs with axially extending blades comprising connecting discs in turn alternately axially to build up one and then the other of two relatively rotatable members by connecting a first stator disc having blades projecting from oppositely facing faces to a stator shaft, assembling a rotor around the first stator disc by attaching one end rotor disc to a bearing on the stator shaft, disposing an intermediate rotor disc against an opposite face of the first stator disc to the end rotor disc, and attaching the intermediate rotor disc to the end rotor disc at an outer radius, then bringing another stator disc up to the intermediate rotor disc and attaching the another stator disc to the stator shaft, and assembling the rotor and stator discs thus alternatively until a second end rotor disc finishes off the assembly on a second bearing on the stator shaft.
A turbine comprising two relatively rotatable parts, relatively rotatable disc members having an axis of relative rotation and facing each other, each disc member having blade members arranged in at least one co-axial ring, the blade members of each disc member extending towards the other disc member and axially overlapping the blade members of the other disc member and the rings being of different diameters whereby the blades of one disc member are closely radially spaced from the blades of the other disc member, there being working fluid inlet and outlet means for working fluid flow in a generally radial direction, at least one of said parts having one of said disc members with blade members on oppositely facing faces, and another of said parts having a plurality of said disc members disposed axially either side of said disc member of said one part, said plurality of said disc members of said one part being connected at an outer radius by a casing.
A turbine comprising a stator disc and rotor mounted for relative rotation, and relatively rotatable disc members having an axis of relative rotation and facing each other, said relatively rotatable disc members including axially spaced apart end disc members attached to bearings on a stator shaft, and a plurality of interdigitated stator and rotor disc members interposed between said end disc members, said stator disc members being connected to said stator shaft at an inner radius, and said rotor disc members being connected to said end disc members at an outer radius, each said disc member having blade members arranged in at least one co-axial ring, the blade members of each disc member extending towards another disc member and axially overlapping the blade members of another disc member and the rings being of different diameters whereby the blades of one disc member are closely radially spaced from the blades of another disc member, there being working fluid inlet and outlet means for working fluid flow in a generally radial direction.
A turbine comprising relatively rotatable disc members having an axis of relative rotation and facing each other, each disc member having blade members arranged in at least one co-axial ring, the blade members of each disc member extending towards the other disc member and axially overlapping the blade members of the other disc member and the rings being of different diameters whereby the blades of one disc member are closely radially spaced from the blades of the other disc member, there being working fluid inlet and outlet means for working fluid flow in a generally radial direction, one of said disc members being on a shaft mounted in bearings and constituting a rotor, said rotor comprising a plurality of said disc members connected to an outer radius by a casing.
