Abstract
Gas turbine engines are complex devices that convert air and fuel into a gas–air mixture, which is used to create jet thrust. Gas turbine engine parts undergo increased loads, in particular, temperature loads. High-strength materials are used to manufacture these parts, and a class of heat-resistant nickel-based alloys are used for parts operating at high temperatures. Turbine discs for gas turbine engines with operating temperatures up to 800°C are one of the most heavily loaded parts. High demands are placed on disk heat-resistant alloys and their manufacturing process, including heat treatment. It is necessary to strictly control the technological parameters of the heat treatment mode, including the heat treatment temperature and the cooling rate of semi-finished products. The software for a control system for a given mode of a variable thermal profile is developed in this work. The structure of the system, its organization, and development and debugging stages are described. Algorithms have been developed to control heating of a muffle furnace and a cooling unit. The developed program allows the heat treatment of the stamping of the disk of a gas turbine engine according to a preselected mode. This makes it possible to obtain the required structure of a nickel-based deformable superalloy, which in turn significantly increases the operation characteristics.
