Slotted bladeless turbine disc

Abstract

A slotted bladeless turbine disc stamped or otherwise formed from a single solid sheet of material with slots formed in the disc to redirect fluid passing through it is disclosed and illustrated in FIG. 1 and FIG. 2 . The form of the slots is curved, slanted and aligned at an angle to the plane of the disc and along a radial from the center of rotation of the disc in such a manner as to force fluids passing through the disc to change direction. Reaction forces of the fluid on the many slots in the disc creates a resultant rotational force on the center of rotation of the disc and thus on the rotatable shaft to which the disc is rigidly attached. To form a turbine one or more slotted discs are assembled on a shaft and enclosed in a case.

1 . A turbine disc for rotating machinery, 
 comprising a disk and a plurality of slots; each slot comprising 
 a shaped hole in the disk and  
 an adjacent tab formed from the material punched or otherwise extracted from the hole.  
   
   
   
       2 . A bladeless turbine disc according to  claim 1  for use in rotating mechanisms, whereby blades and blade attachments to a hub are eliminated from turbine rotor and stator discs, comprising: 
 a disk of rigid material,    a plurality of slots formed within a disk, generally arranged in a pattern around its center of rotation, each slot comprising: 
 a hole having a predetermined shape through which fluid material flows, thereby forming an orifice,  
 a flat or concave shaped tab, generally being located on one side of the disc, and oriented along a disk radial, and tilted at an angle to the surface of the disk, and being adjacent to the hole, thereby providing a means for deflecting or redirecting fluid material flowing through the orifice;  
   a centrally located hole cut at the center of rotation of the disc, thereby providing a means to pass a rotatable shaft of predetermined cross section through the hole, comprising: 
 a means to rigidly attach the bladeless disc to the shaft thereby forming a rotor disc,  
 a means to attach a bearing or bushing between the bladeless disc and the rotating shaft, thereby forming a stator disc.
