Tesla turbine

Abstract

Abstract of the Invention An improved turbine using the edge of the blades of the working surface instead of the blade's face, and further utilizing both expansion blades and adhesion discs.

What is claimed is:  
     
         1 . A Tesla turbine, wherein the improvement comprises: 
 a rotor shaft; a plurality of rotor discs each having a given outside diameter, and each including a plurality of spaced apart exhaust ports arranged in a circle of smaller diameter than said outside diameter, a plurality of spaced apart bolt holes arranged in first and second concentric circles, all of which are centered about a centrally located shaft opening for receiving a portion of said rotor shaft; a plurality of rotor blades, each including a plurality of radially directed, equally spaced, successive blades arranged in a circle about a centrally located hub portion, a plurality of spaced apart bolt holes arranged in first and second concentric circles, all of which are centered about a centrally located shaft opening for receiving a portion of said rotor shaft, said plurality of blades and hub being formed ˜om a single piece of material; alternating ones of said plurality of rotor discs and plurality of rotor blades being assembled on said rotor shaft, with said exhaust ports of the former opening into the spaces between associated said blades, thereby forming a rotor assembly; a housing including: 
 two opposing end plates; a case ring between said end plates, said case ring providing a circumferential portion of said housing; a fluid inlet port located on said case ring of said housing; said assembly of said plurality of rotor discs and plurality of rotor blades on said rotor shaft being rotationally mounted within said housing; and an exhaust manifold being mounted on said housing for receiving exhaust fluid expelled from said rotor assembly and housing.  
   
     
     
         2 . A turbine utilizing the edge of turbine blades as the working surface instead of the blade's face.  
     
     
         3 . A turbine comprising both expansion blades and adhesion discs.
