The invention relates to turbine rotors and can be used in the field of plant engineering, power plant and General engineering.

Known turbine rotor having a working channel of the entrance of the working fluid at the periphery of the rotor and out through the hollow shaft of the rotor is made to rotate.

This rotor for rotation which is used viscous friction of the working fluid, the direction of movement to the Oia known (D. J. Neil. Electric Prometheus. IL N 8, 1979, S. 34-35).

The disadvantage of this rotor is insufficient efficiency of conversion of the potential energy of the working fluid into kinetic energy of rotation of the rotor.

The objective of the invention is to increase the efficiency of conversion of potential energy of the working fluid into kinetic energy of rotation of the rotor.

This object is achieved by performing on the inner surface of the curved profile of the working channel profile of spiral grooves, oriented across the direction of movement of the working fluid. Moreover, the grooves on the surface can be partially executed.

The invention is illustrated by drawings, where:

in Fig.1 shows a rotor with partial cutting, longitudinal section;

in Fig.2 shows the trajectory of the conditional streams of working fluid across the working channel without rifling;

in Fig.3 - the same, in the channel with partial cuts;

in Fig. 4 - the same, with annular and spiral (trajectory which such ring) meats;

in Fig.5 - the trajectory of the conditional streams of working fluid along the channel without rifling;

in Fig.6 - the same, with partial cutting;

in Fig.7 - the same, with the ring and SPIRA is;

in Fig.9 - the same, with partial cutting;

Fig 10 - the same, with the annular cutting;

in Fig.11 - the same, with spiral cuts.

The rotor 1 is made with profile grooves 2 in a curved profile working channel 3 with 4 in it the working fluid at the periphery of the rotor and the outlet 5 through the hollow shaft of the rotor 1.

When the working body under pressure through peripheral input 4 enters the curved profile working channel 3.

When the movement of the working fluid from the inlet 4 to the outlet 5 of the grooves 2 and the curvature profile of the channel 3, the trajectory of the conditional streams of working fluid has a spiral circulation in nature.

When the motion of the stream of the working fluid along a curved working channel 3 on her acting centrifugal force in accordance with the current radius, depending on the speed and density of the working fluid.

A stream with a large current radius acts and a large centrifugal force, therefore, by the streams of working fluid different according to the magnitude of the centrifugal force.

Reduce speed streams of working fluid under the action of its friction against the walls of the working channel 3 - the difference between the centrifugal force increases.

Trickle going on at the same time, getting the required velocity vector under the action of the jet of the working fluid, because the pressure at the inlet 4 is greater than at the outlet 5, the stream is accelerated under the action of the difference of the centrifugal force becomes large current radii, is on thread 2, then the circulation is repeated.

The difference between the centrifugal force of the streams of working fluid, the friction on the wall of the working channel 3 and the change of the velocity vector in streams, incoming and were on thread 2, circulate streams of working fluid in the working channel, which maintains a constant transmission of impulses to the rotor 1 from the working fluid.

The effect of working fluid on the profile grooves 2 curved profile of the working channel 3, the coincidence of the directions of movement of the working fluid and the rotation of the rotor 1, and viscous friction of the working fluid on the wall of the working channel 3 in the amount of action allow to increase efficiency of conversion of potential energy of the working fluid into kinetic energy of rotation of the rotor 1.
