Abstract

The invention allows to increase the efficiency of the turbomachine. The turbomachine contains a stator and a rotor placed inside it. On the surfaces of the rotor and stator facing each other there are slots 5, 6, made on a semi-narrowed back. The area of the grooves 5 located on the stator is made increasing along the working fluid. The stator is equipped with ribs located on its outer surface. Such a design of the turbomachine reduces the input loss during the subsequent expansion, provides the change in the expansion volumes along the working fluid. The ribs reduce thermal stresses in the stator. In order to prevent uniform heat removal, the fin can be. made of different intensity, i.e. greater where the expansion surface is smaller, and smaller where this surface is larger. 1 hp f-ly, 3 ill. i (L

Description

FIELD: turbine engineering.

The purpose of the invention is to increase the efficiency of the turbomachine,

FIG. 1 shows a section of a Turbo engine; in fig. 2 is a section A-A in FIG. one; on fig.Z - V1ed B on fig. one.

Turbomachine contains the stator 1 s

the working fluid, which at the beginning and end of the gas expansion cycle should be equal to the maximum degree of expansion, providing an isothermal expansion process. In order to reduce the thermal stresses in the stator 1 of the turbomachine, fins 7 are made on its outer surface.

Channels 2 and 3, respectively, supply the uniform removal (supply) and removal of the working fluid and the rotor 4 placed inside it;

The area of the notches 5 located on the stator 1 is made increasing along the working medium, the stator 1 is equipped with ribs 7 located on its outer surface.20

Turbomachine works as follows.

Compressed gas through channels 2 gets into the flow part of the turbomachine, by: hence the grooves expand, and 5 and 6. The gas gives up its energy, driving the rotor 4 to rotate.

heat finning can be of varying intensity, i.e. greater where the surface of the expansion volume is smaller, and smaller where this surface is larger.
