Abstract

The object of research is high-stressed parts of high-temperature gas-turbine engines (GTE) and gas-turbine plants (GTP) with the complex of branched channels.

The aim of the research is to develop a methodology for creating and designing of cooled structures in high-temperature gas turbines of GTE and GTP of 5-6^th generations by using the experimental database to ensure the competitiveness of aircraft engines due to innovative technologies used for their creation.

The complex program of thermal designing the heat- stressed parts of the gas-turbine engines and gas-turbine plants for increasing the reliability and lifetime of the engine is developed. The methodology of mining the heat-stressed parts on the stage of the design- technological adjustment of cooled parts is developed. New criteria relations dependence characterizing the thermal and hydraulic conditions of perspective systems of heat exchange intensification of the cooled gas-turbine blades are obtained. The data bank for channels with complex configuration of modern systems for intensifying heat exchange in the high-temperature gas turbines of gas-turbine engines and gas-turbine plants is compiled.

Scientific novelty of the research as follows: the complex program for thermal designing and improving the structures of heat-stressed parts in GTE and GTP aiming to increase the reliability and service life of the engine by using the highly informative methods of research and by controlling of their functional parameters is developed.

The developed bases of technology of working off of the constructions of heat-stressed parts on the stage of the design-technological operational development allow to reduce the complexity and expense for the creation of prototypes of the aircraft equipment.

The received samples of the design elements of the aircraft equipment can be used in the development and creation of modern and perspective gas-turbine engines, and also in the process of building of heat-engineering devices.
