TURBINE DESIGN AND MANUFACTURING METHOD Russian patent published in 2022 - IPC F01D5/02 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in the manufacture of turbines. The method for manufacturing the turbine (3), taking into account the change in the material of the impeller of the rotor (102) of the turbine, consists in taking into account that the time required for the temperature of the impeller (102) to reach from the first temperature to the second temperature during the start of the turbine is the time of temperature increase, and taking into account that the distance between the surfaces on the upstream side and the downstream side of the impeller is the distance between the surfaces. The ratio of the times of temperature increase is determined, which is the required ratio of the time of temperature increase after the material change to the time of temperature increase before the material change. The distance between the surfaces is determined after the material changes based on a certain ratio of temperature rise times. The shape of the impeller is determined after changing the material based on a certain distance between the surfaces. The turbine (3) is manufactured with the reproduction of a certain shape of the impeller on the rotor (102) of the turbine.

EFFECT: reducing the time required for the manufacture of the turbine, in accordance with the change in the material.
