Extending the service life of gas turbine power plants used at mineral deposits

This article deals with the issue of improving the reliability of gas turbine engines (GTEs) and extending their service life. GTEs are used as power generators at mineral deposits. For this purpose, a unique turbulator for the turbine blade design is presented with the results of an aerodynamic experiment and a CFD simulation of the flow through a spiral turbulator. The results are compared. The design of the cooling turbine blade with a spiral turbulator includes the use of graphene as a construction material, a revolutionary material of the 21st century with a large cooling capacity. Promising ways of obtaining such a turbulator the purpose of turbine cooling are considered. The spirals can be effectively used in situations where it is necessary to turbulize the air or decrease the flow pressure.
