CONNECTOR AND CONNECTING DEVICE WITH THERMAL MISMATCH PROTECTION Russian patent published in 2022 - IPC F01D9/04 

FIELD: aircraft engineering.

SUBSTANCE: invention relates to the field of the external annular component of a turbine of a turbine aircraft engine, in particular, to a connector with a cavity section and a connecting device with protection against thermal mismatch. Between the outer annular component of the turbine made of ceramic matrix composites and the metal intermediate casing, a connector and a connecting device with protection against thermal mismatch are made. The connector rod contains a cavity section and a cylindrical section. The cavity section consists of a central shaft, a plurality of supporting rib plates extending outward from the peripheral surface of the central shaft and inclined radially relative to the central shaft, and a plurality of outer annular plates are arranged around the central shaft, with a peripheral gap between adjacent outer annular plates. The central shaft and the outer annular plate are connected by means of a supporting rib plate, and the central shaft is connected to a cylindrical section.

EFFECT: invention reduces mismatch in all directions due to thermal deformation of the connecting and assembly structure.
