Reaction rotor turbine

Claim 1

A turbine stage for power generation comprising: a. a reaction rotor for producing said power; said rotor being rotated at a predetermined speed; said rotor having reaction nozzles mounted near the periphery of said rotor; said reaction nozzles being oriented to discharge a fluid backward in a direction that is away from the direction of rotation of said rotor; said rotor being hollow and having a first cross sectional area at any radial distance that is greater than a second cross sectional dimension of said reaction nozzles so as to effect a peripheral pressure that is greater than the pressure at the inlet to the rotor downstream of a set of fluid feeder nozzles; said reaction nozzles being at least converging and sized and shaped to provide for maximum exit velocity attainable for said fluid from said nozzles relative to said rotor depending on the pressure and enthalpy differential available between entry and exit ends of said nozzles; b. a fluid feeder; said feeder being stationary and mounted concentrically interiorly of said rotor; said feeder being connected with a source of said fluid at an elevated pressure for supplying fluid to said reaction rotor; said feeder being equipped with fluid feeder nozzles arranged to discharge said fluid in a direction that is substantially the same as the tagential and at a speed greater than the speed of the reaction rotor in the area where said fluid enters said rotor; said fluid feeder nozzles being at least converging and sized and shaped to provide for highest attainable velocity for said fluid depending on the pressure differential available between entry and exit ends of said fluid feeder nozzles; d. a casing for providing support for said reaction rotor and said fluid feeder; e. a shaft connected with said rotor and journalled in said casing for supporting said rotating reaction rotor; f. bearing means disposed about said shaft for reducing friction; and g. fluid being flowed through said turbine stage from an inlet pressure upstream of said fluid feeder to a discharge pressure downstream of said reaction nozzles; said inlet pressure being greater than said discharge pressure; said fluid being flowed from said fluid feeder nozzles at a speed greater than the tangential velocity of said rotor at the same radial distance for effecting a greater power output on said shaft.

Claim 7

A method of generating power in a reaction turbine comprising the steps of: a. accelerating a fluid to a first velocity and direction with respect to a radial extending outwardly from a central longitudinal axis of a fluid feeder; b. passing the accelerated fluid at said first velocity into a rotating rotor; said first velocity being greater than the tangential velocity of the rotor at the same radial distance from said axis; said direction being substantially tangential to said radial velocity direction; c. causing said fluid to flow in an arcuate radially outward path with sufficient angular velocity to cause sufficient centrifugal force to pressurize said fluid within said rotor such that the pressure of said fluid at the periphery of said rotor is greater than the pressure at the inlet to said rotor; and discharging said fluid through reaction nozzles mounted at the periphery of the rotating rotor in a direction that is opposite to the tangentiAl direction of rotation for producing thrust and generating torque on the rotor and its shaft for producing power efficiently.

Claim 8

A method of generating power in a reaction turbine comprising the steps of: a. accelerating a fluid to a first velocity and direction with respect to a radial extending outwardly from a central longitudinal axis of a fluid feeder; b. passing the accelerated fluid at said first velocity into a rotating rotor; said first velocity being greater than the tangential velocity of the rotor at the same radial distance from said axis; said direction being substantially tangential to said radial velocity direction; c. causing said fluid to flow in an arcuate radially outward path with sufficient angular velocity to cause sufficient centrifugal force to pressurize said fluid within said rotor such that the pressure of said fluid at the periphery of said rotor is greater than the pressure at the inlet to said rotor; and discharging said fluid through reaction nozzles mounted at the periphery of the rotating rotor in a direction that is opposite to the tangentiAl direction of rotation for producing thrust and generating torque on the rotor and its shaft for producing power efficiently.
