The invention relates to mechanical engineering and can be used as turbines to generate electricity, pneumatic and hydraulic turbine as a drive in road, and when drilling oil and gas wells.

Known currently used single-and biratori Kaplan turbines, which are used for the rotation of the rotor. High-speed flow of the working fluid (water, gas, working solution) does not provide a large torque on the working shaft.

Known biratori turbine (patent # 80162 and patent No. 1716173), which have the same drawbacks as single, they are structurally designed only for reverse rotation of the working shaft.

The prototype was taken turbine gearbox turbodrill (patent RU №2112856).

The purpose of this invention is to provide a turbine, the power of which is higher existing at smaller sizes.

The objective is achieved due to the fact that the turbine blades affects the static pressure of the working fluid generated by the height of liquid column above the turbine (Pascal's law P=f (H), where H is the height of the liquid column).

Piraterna walking turbine is characterized in that it contains asynchronous gearbox with gear, with inner and outer rotors are placed coaxially on the coaxially arranged shafts, and loped the inner and outer rotors are in the interscapular space to each other to touch with respectively with the inner cylindrical surface of the outer rotor and the outer cylindrical surface of inner rotor with alternate turning of the rotor in one direction relative to each other on the calculated angle from workflow solution that has the ability to fill in the interscapular space of the rotors through the spools mounted on the inner and outer rotors of the turbine, which are respectively rigidly connected with the inner and outer coaxial shafts asynchronous gearbox with oval gears and variable gear ratio that enables the asynchronous rotation in one direction of the inner and outer rotors Bertomeu turbine.

Turbine has an inner (5) and outer (6) the rotor blades which are mutually in the interscapular space to each other, and the rotors are fixed to the inner (7) and outer (8), respectively, the shafts asynchronous gearbox with variable gear ratio (2), there is also a spool-valve - inlet (9) and outlet (10)fixed on the inner and outer rotors of the turbine.

The turbine operation is carried out as follows.

Working fluid (water, gas, the working solution can pass through a ring channel (11) inside the turbine through the valve (9) in the interscapular space of the rotor and rotating work shaft (17) through the differential (3) alternately from the inner (5) or from outside (6) rotors Bertomeu turbines, which are rigidly connected, respectively, with the inner (13) and outer (14) shaft asynchronous gearbox with variable gear ratio, and go through the slide valve (10) in the hollow shaft (17) through channel (12) and later in the annulus. For alternate step turning of the inner and outer rotors Bertomeu turbine in one direction at a certain angle α5 and the angle α6 (2) has a two-stage asynchronous gearbox (2) with variable gear ratio, coupled shafts (13 and 14) with inner (5) and outer (6) rotors Bertomeu turbine, respectively, a step (20) of the gearbox is designed for alternating (walking) the movement of the rotor during rotation, etc the guy step (21) to return the relative position of the rotor to its original state for a period of one turnover of the Central gear (18) (figure 3), fixed to the inner shaft (13) asynchronous transmission, and for one rotation of the Central gear (19), fixed on the outer shaft (14) of the gearbox.

SUBSTANCE: turbodrill turbine comprises stator with blade ring and inner rim, rotor with blade ring and hub. Design angles of stator flow inlet and outlet directions α2 and α1 and rotor flow inlet and outlet directions β2 and β1 are related by theoretical correlations with peripheral velocity determined in idle and optimal (shock-free) mode of turbine operation. Stator and rotor blade ring blades defining above design angles as distinct from prior art turbines are formed so that shock-free regime of flow around the stator and the rotor is realized at different peripheral velocities, wherein above shock-free regime of stator flow-around is performed in retardation mode, shock-free regime of rotor flow-around is performed in runaway mode thereof. Above stator and rotor angles are correlated as α12≤π/2 and β21≤π/2 (in the case of positive reactive turbine) and β12≤π/2 (for negative reactive turbine). The stator rim has surface of lesser diameter having conoid shape and converging towards lower cross-section thereof so that minimal annular gap defined by rotor hub is 0.05-0.3, preferably 0.1-0.2 of radial stator blade height and inner blade ring surface of lesser diameter has conoid shape and is converged to upper section so that radial rotor blade height ratio in lower and upper sections is equal to 0.7 - 0.95.
