METHOD FOR PRODUCING MECHANICAL ENERGY, SINGLE-FLOW AND DOUBLE-FLOW REACTIVE TURBINES AND TURBO-REACTIVE INSTALLATION THEREFOR Russian patent published in 2018 - IPC F01D1/32 F01D15/08 

FIELD: machine building.

SUBSTANCE: invention relates to mechanical engineering, in particular to pneumatic, gas and steam turbines for driving electric generators, propulsion systems, compressors of refrigeration units, heat pumps. Method of obtaining mechanical energy is realized in single-flow and double-flow jet turbines, and made on the basis of their turbojet installation, includes the flow of the working fluid into the channels of a single-flow or double-flow centrifugal impeller, in which it is compressed, the jet turbine starts to work with the initial pressure of the working fluid that is insufficient for starting and reaching the normal operating mode by means of forced rotation of the centrifugal impeller shaft, and with an increase in the rotational speed of the centrifugal impeller to values close to the calculated, the working fluid is compressed due to the combination of both the acting centrifugal channels and centrifugal forces, the obtained compressed working fluid with high values of speed, temperature and pressure enters the internal cavity of the toroidal collector, where it is braked, when this is an intensive turbulent mixing of the mass of the working fluid in the entire volume of the reservoir cavity with the alignment of density gradients, temperature, pressure and speed with a decrease in flow rate and increase in pressure in it to the maximum possible value, namely, to the pressure of the inhibited flow, under the action of which the working fluid accelerates in supersonic jet nozzles and flows out of them into the surrounding space at supersonic speed, while creating a reactive power impulse that ensures rotation of the centrifugal impeller single-flow or double-flow jet turbine.

EFFECT: technical result of the claimed invention is to increase the efficiency of obtaining mechanical energy in single-flow and double-flow jet turbines and in a turbojet, made on their basis, with suboptimal parameters of the working fluid in front of the jet turbine.
