Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a thermal barrier coating working condition simulation and real-time monitoring device. Background technique [0002] Aeroengines are known as the "heart" of aircraft and play a decisive role in the development of the aerospace industry. The key parameter of an engine is its thrust-to-weight ratio. With the increase of the thrust-to-weight ratio, the temperature at the front inlet of the aeroengine turbine has exceeded 1700°C. The substantial increase in the inlet temperature of the turbine undoubtedly puts forward higher requirements on the performance of the superalloy material and thermal protection technology of the hot end parts of the engine. The thermal barrier coating system is a multilayer functional material with high temperature resistance and high heat insulation. It is composed of a top ceramic layer that acts as heat insulation, delays oxidation, and resists erosion / cor...

AI Technical Summary

Problems solved by technology

[0003] Aeroengines have an extremely harsh multi-field coupling service environment, and the working conditions are extremely complex, requiring a large amount of experimental data to test materials. However, traditional test methods cannot accurately simulate the service environment of aeroengines, which limits the thermal barrier coating in coupling environments. The research on the damage and failure process of the layer cannot meet the actual needs, and requires a variety of monitoring equipment to monitor the simulation process, and the integration level is not high
