Description

technical field

[0001] The invention relates to a gas turbine, which has a plurality of working blades arranged on a turbine shaft which are respectively assembled into a working blade group and several guide blades which are respectively assembled into a guide blade group and connected with a turbine casing. Background technique

[0002] Gas turbines are used in many fields to drive electrical generators or working machines. Here, the energy contained in the fuel is used to generate the rotation of the turbine shaft. For this purpose, fuel is burned in a combustion chamber into which is also fed air compressed by a compressor. The high-temperature and high-pressure working medium formed by fuel combustion in the combustion chamber passes through a turbine unit connected behind the combustion chamber, where it expands to perform work.

[0003] In order to generate the rotary motion of the turbine shaft, a number of working blades, usually assembled i...
