RADIAL BIROTATIONAL ACTIVE-REACTIVE TURBINE (VARIANTS)

FIELD: mechanical engineering.SUBSTANCE: inventions relate to mechanical engineering, namely to turbines for driving the shafts of electric generators, compressors, pumps and other devices. In the first version of the rotary radial active-reactive turbine (fig.1, 2, 3 and 4), the working body enters through the pipeline (2) into a single-flow closed centrifugal wheel (7) of the rotor (3) with tangentially mounted Laval nozzles (17) on its periphery, in which the working fluid is compressed with an increase in its pressure and enthalpy and its subsequent supersonic flow through the nozzles (17) to the profiled blades (24) of the rotor (19), made in the form of two disks (20 and 21) located coaxially on both sides of the rotor (3), rigidly connected along the periphery by blades (24) and rigidly with coaxial shafts (22) and (23) with the possibility of rotation in the direction opposite to the rotation of the rotor (3). The shafts are connected to the payload. In the second version of the turbine (fig.5, 6 and 7), the working body enters through pipelines (2 and 2') located in opposite directions, into two identical, made in a mirror image, rigidly fixed on the shaft (4) and rigidly connected by flanges using a frame (29) of an annular shape of single-flow closed centrifugal wheels (7 and 7') of the rotor (3) with tangentially mounted Laval nozzles (17 and 17') on its periphery. The compressed working body flows through the nozzles (17 and 17') to the profiled blades (24) of the second rotor (19), made in the form of two disks (20 and 20'), connected rigidly, each with its own shaft (22 and 22'), respectively, and between each other rigidly along the periphery of the blades (24), made in the form of grooves, the axis of which is parallel to its shafts (22 and 22') and fastened rigidly with a power ring (30). The shafts (22 and 22') are located coaxially and in opposite directions, coaxially with the shaft (4) of the rotor (3), while they are connected through a corresponding transmission to the payload.EFFECT: technical result of the claimed rotary radial active-reactive turbines consists in increase in absolute and specific power.6 cl, 7 dwg Изобретения относятся к машиностроению, а именно к турбинам для привода валов электрогенераторов, компрессоров, насосов и других устройств. В первом варианте роторной радиальной активно-реактивной турбины (фиг.1, 2, 3 и 4) рабочее тело поступает через трубопровод (2) в однопоточное закрытое центробежное колесо (7) ротор
