Abstract:
1. A spiral plane drag turbine comprising a housing; a fluid inlet; a rotor assembly having a length and a direction of rotation, wherein the rotor assembly has a plurality of closely related blades which are positioned to form a spiral pathway formed by a plurality of closely related disks that are intertwined on the shaft, each disk having at least one blade with a leading edge and a trailing edge, wherein each leading edge is offset from the trailing edges of the surrounding closely related blades which are positioned to form said spiral pathway; a narrow slice cut out on each disk in a way that the resulting blades are angled slightly so that their leading edges can be overlapped with the trailing edges of the blades of the adjacent disks, also forming an additional plurality of spiral pathways; wherein said rotor assembly is formed by a number of disks that have portions cut out to form blades and the cut out portions are equal in size to the remaining portions which fixed into the shaft in a staggered fashion form spiral pathway in said rotor assembly; a shaft connected to the rotor assembly; and a fluid outlet, wherein a working fluid enters the fluid inlet, flows through the spiral pathway in the rotor assembly's direction of rotation, and exits through the fluid outlet.
