Selecting Materials for Brazing a Honeycomb in Turbine Engines. To reduce leakage flows in turbo machines, tight operational clearances between stator and rotor parts are desirable. With reduced clearances, the risk of rub contact increases. In such situations, the stator is fitted with an abradable structure or coating that minimizes damage to.

Honeycomb-Seal Brazing By Dan Kay Figure 1 Figure 2 September 17, 2019 Question: We are brazing honeycomb for a turbine seal in an aircraft jet engine using nickel filler metal. The filler metal wicks up the nodes in the honeycomb during brazing, however, forming a hard crown-like surface on the top of each of the honeycomb cells.

Two primary purposes for using honeycomb for rotor-blade tip seals (rubbing seals, abradable seals, etc.) are: (1) to provide a gas-path seal to prevent hot engine gases from getting around the ends of the turbine rotor blades, and (2) to simultaneously provide a sacrificial surface against which the rapidly rotating blades will rub.

This work is focused on the checking of the correctness of the brazing process of honeycomb seals to stationary elements of aircraft turbine engines. It describes this process, paying attention to the aspects that have a fundamental impact on whether the seal will be brazed to the base as required, or whether unacceptable areas of non-brazing will appear. The aim of the study was to check the.
