Abstract

A description of the development of the technology for obtaining parts of the hot path of gas turbine engines by the method of directed crystallization from superalloys are considered. The analysis of the existing specialized equipment used in Russia, the USA, Germany and other countries to produce blades with a directional and monocrystalline structure is carried out. The prospects of the method of directed crystallization with a liquid-metal cooler in the production of gas turbine engine blades for both modern and promising gas turbine engines are clearly demonstrated.
