Abstract: A turbine has a disc pack rotor with a central aperture-free or solid disc that divides the pack into two equal portions. The annular discs of each portion have aligned, central and unobstructed exhaust openings and the outer end disc of each portion is a support member having a webbed hub that is attached to a respective drive shaft journalled in the turbine casing. A stationary circular nozzle assembly closely surrounds the outer circumference of the disc pack to form one or more convergent-divergent nozzles that guide motivating fluid from an outer casing plenum into spaces between neighboring discs. The discs are separated from one another and interconnected by fences that guide the motivating fluid to the exhaust openings in each pack portion. Thus, fluid enters the pack circumference and is split into two parts by the center disc to exhaust in relatively opposite directions. The shaft for each pack portion preferably terminates at the outer support disc to form a two-direction "shaftless" rotor.

Abstract: A multi-stage turbine has an inflow disc pack that directs motivating fluid to an outflow disc pack on the same shaft. The packs are fitted to rotate between plates that web a turbine casing interior and fluid entry into the casing to the inflow pack is via nozzles in a ring assembly fixed to the casing. Each disc pack is made up by spaced apart discs with fences that guide the motivating fluid first through the inflow pack and then the outflow pack. A central passageway in the packs and adjacent the shaft communicates fluid inflow to outflow. Fluid exhaust is through exits at the casing bottom. In one version, the disc packs are conical and when seen from the side, the packs with webbed plates are X configured in section. In another version, the inflow pack is flat, the outflow pack conical and the casing of both versions are configured to provide low losses and maximum strength. The nozzles can be convergent-divergent in a plenum located adjacent the inflow pack circumference.

Abstract: This invention relates to turbines wherein fluid pressure temperature energy is released, via its passage from a high-speed nozzle delivery mounted externally and tangentially, to closely-spaced together circular profiled sheet metal, or ceramic, plates, preferably plate members that have concave and convex surfaces, at least in part, which form high surface area bodies of revolution. An assembly of disc members form the turbine rotor within which the surface adhesion effect of the traversing fluid imparts rotation to the rotor before it is finally expelled through an exhaust duct formed by centrally disposed exits in the assembly. A spiral-like fence baffle on the rear face of the plates tie adjoining surfaces together and provide expanding fluid flow channels between adjacent plates.
