    Air turbine, which comprises a stator (8), which is provided with a guide wheel (9) for moist air and with guide passages placed between the guide blades (14), a rotor (10), which is provided with a runner (11) and with runner blade passages placed between the runner blades (15), as well as an annular intermediate space (12) between the guide blades (14) of the stator (8) and the runner blades (15) of the rotor (10). The air turbine further includes a control unit (1) for controlling the temperature of the air to be supplied to the guide wheel (9). According to the invention, the control unit (1) is arranged so as to adjust the temperature of the air flowing to the turbine to a temperature of 2 to 10<o> C, whereat the absolute pressure after the guide wheel (9) is 0.8 to 0.4 times the absolute pressure before the guide wheel (9). The axial dimension of the intermediate space (12) is at least 30 % of the axial dimension of the runner blades (15), and the intermediate space (12) is widened in the radial direction beyond the radial dimension of the passages between the runner blades (15) so as to produce whirling that prevents freezing at the inner and outer edges of the intermediate space (12). In the air turbine in accordance with the invention, wet or moist air may expand and cool down to temperatures that are considerably below the freezing point of water without disturbance or prevention of the operation of the turbine by formation of ice on the faces of such turbine parts as are in contact with the air flow passing through the turbine.

The axial gap 3 is at least 30% and preferably 50% of the axial size of the blades 2. The air entering the turbine is divided into three streams, the passage through channels 6 and 9 and the bypass channel 10.

    The invention relates to turbine construction, in particular to air power plants.
    The aim of the invention is to improve the reliability of an air power plant.
    FIG. 1 shows a power plant, a longitudinal section; in fig. 2 - axial air turbine stage; in fig. 3 is a section A-A in FIG. 2
    The air power plant contains a turbine 1, the guide vanes 2 of which are installed with an axial clearance 3 relative to the rotor blades 4, a cooling heat exchanger 5 installed in the channel 6 connected to the air inlet 7 and parallel to the last heating heat exchanger 8 installed oppositely with respect to the cooling heat exchanger 5 in the additional channel 9. The additional channel 9 is connected to the air inlet 7, which is located between the channels 6 and 9, with air odvod present nozzle 7 bypass passage 10. The air power installation provided with guide gate 11 and 12, which are disposed in channels 10 for 6.9 H when necessary overlap completely or partially their passage sections. The axial clearance 3 is at least 30% (and preferably 50%) of the axial size of the blades 2.
    During operation of an air power plant, the air entering the turbine is divided into three streams,
