This article describes results of experimental functionality check of the developed expert system and database for automated selection of materials, coatings and other preparation types of the main surface parts and assemblies of aviation gas turbine engine air-gas channel. The choice materials results of the main elements of two spool mixed flow turbofan engine are considered: input unit, compressors and high and low pressure turbines, combustion chamber and afterburner, jet nozzle. The simulation of different flight regimes results are shown – on the ground (flight altitude is 0, flight Mach number is 0) and on the flight altitude 2.5 km with Mach number 2.35. The selection results of different coatings and other preparation types of the main surface parts and engine air-gas channel assemblies are shown. Findings are compared with materials of two spool mixed flow turbofan engine of the fourth generation construction.
