Abstract

The trends in the development of a technology for the production of the hot gas path parts of a gas turbine engine (GTE) by directional solidification from superalloys are considered. The existing special-purpose equipment used in Russia, the United States, Germany and other countries to produce blades with a directional and single-crystal structure is analyzed. The prospects of directional solidification with a liquid metal cooler in the production of GTE blades for both modern and promising GTEs are clearly demonstrated.
