GENERATING METHOD OF MECHANICAL ENERGY, AND RADIAL JET ROTARY ENGINE WITH ROTORS OF OPPOSITE ROTATION FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F01D1/32 

FIELD: engines and pumps.

SUBSTANCE: method and device for generation of mechanical energy by using rotors of opposite rotation with nozzles includes supply of working medium to laval nozzle in the rotor of the first stage, acceleration of working medium in nozzles to supersonic speed so that reactive force and torque moment acting on rotor and transmitted to the shaft is created, and supply of accelerated working medium to closed space after rotor of the first stage so that compression shock of working medium occurs in that closed space between rotors of the first and the second stages. Then, working medium is supplied to convergent nozzles of rotor of the second stage and accelerated in nozzles so that reactive force and torque moment acting on rotor of the second stage and transmitted to the shaft is created. At least some part of each rotor is made in the form of a ring. One of those rings encloses another one. Inlets and outlets of nozzles lie on cylindrical surfaces of rings and central lines of nozzles lie in the plane perpendicular to rotor rotation axis. Acceleration of working medium in nozzles of each rotor is performed with rotation of flow in each nozzle to the opposite side relative to direction of flow at the inlet to that nozzle. Acceleration of working medium in nozzles of rotor of the second stage is performed with rotation of flow to opposite side in relation to direction of flow turn in nozzles of rotor of the first stage. Device can bring generator shaft into rotation.

EFFECT: reduction of energy losses, improvement of efficiency and decrease of weight.
