Abstract:
1. A method of efficiently generating and extracting power from a flow of a compressible fluid for doing useful work, comprising: a) inducing and sustaining a chosen mass flow of said compressible fluid by a vacuum source, (b) conducting said chosen mass flow of said compressible fluid from said vacuum source into and through a set of two or more conical nozzles formed within a rotor, said rotor being cylindrical and mounted on a central shaft, or axle, each said nozzle in said rotor having an equal minimum or throat cross-sectional area, and where, moreover, said throat cross-sectional area in each said nozzle is also that area which will pass an equal portion of said chosen mass flow of said compressible fluid at sonic speed, (c) arranging said set of conical nozzles circumferentially and symmetrically in said rotor, said set of conical nozzles being situated in a same plane of rotation, said plane of rotation of said set of conical nozzles being at right angles to an axis of rotation of said rotor, each said conical nozzle having a respective larger flow entrance port situated on an outside rim of said rotor, each said conical nozzle leading through said rotor so that a respective smaller end flow exit port opens into a central, cylindrical inner fluid flow chamber of designed radius inside said rotor, each said conical nozzle being aligned in said same plane of rotation so that said exit port of said conical nozzle is tangent to said rim of said inner fluid flow chamber at said designed radius, (d) each said conical nozzle having a minimum cross-sectional throat area at a smaller end thereof, each said throat in each conical nozzle being of a cross-sectional area designed to pass through each said throat at sonic speed an equal partial portion of said chosen mass flow of said compressible fluid, and with a total of all said partial portions of said compressible fluid through all said conical nozzles taken together being equal to said chosen mass flow of said compressible fluid, (e) said chosen mass flow of said compressible fluid exiting said conical nozzles into said inner fluid flow chamber at sonic speed and thus exerting a thrust on said rotor as said mass flow of said compressible fluid passes out from said conical nozzles and into said inner fluid flow chamber, a direction of said thrust being offset from said axis of rotation of said rotor at said designed radius from said axis of rotation of said rotor and thus exerting a torque on said rotor, said torque causing said rotor to rotate in an opposite direction to the direction of said conical nozzle exit flow into said inner fluid flow chamber, said rotor thereby acquiring by reaction force a rotational energy from said thrust of an accelerated fluid flow in said conical nozzle, (f) said inner fluid flow chamber having a downstream exit port of cross-sectional area not less than a combined throat area of said conical nozzles taken together, said mass fluid flow then exiting from said inner fluid flow chamber through said downstream exit port into a flow diffuser, said flow diffuser decelerating said compressible fluid flow and leading it towards a total flow exit port.
