METHOD OF MANUFACTURING AN ABRADABLE SEAL Russian patent published in 2021 - IPC F16J15/00 

Abstract RU 2745839 C1

FIELD: machine building.

SUBSTANCE: invention relates to a method for manufacturing an abradable seal based on a honeycomb structure. The seal decreases deformability due to the redistribution of attachment points in the volume of the seal and ensures high integrity of the finished product while maintaining high manufacturability and high abradability.

EFFECT: when using the proposed method, a sufficient number of attachment points remain in the volume of the seal in the course of shaping the honeycomb structure in the process of machining to keep it in a non-deformable state.
