METAL COMPONENTS AND KMCM COMPONENTS CONNECTION SYSTEM, TURBINE SHOVEL FIXATION SYSTEM AND ROTATING COMPONENT FIXATION SYSTEM Russian patent published in 2017 - IPC F01D5/30 F01D5/28 

FIELD: machine engineering.

SUBSTANCE: connection system for the metal component and the ceramic matrix composite component includes a fixing pin, a ferrule bushing, a first hole in the metal component, and a second hole in the ceramic matrix composite material component. The first opening and the second opening are configured to form a through hole when the metal component and the composite material component are combined with the ceramic matrix. The fixing pin and the ferrule bushing are located inside the through-hole for connecting the metal component and the composite material component with the ceramic matrix. Another invention of the group relates to a system for connecting a segment of a turbine blade of a gas turbine made of a composite with a ceramic matrix to a segment of a metal holder connected by the above-described coupling system.

EFFECT: increasing the reliability of the connection of the metal component and the component from the composite material to the ceramic matrix.
