The aircraft engine can provide power for an aircraft, is known as an 'pearl on a modern industrial crown', and the number of turbine blades in the aircraft engine is the largest, so the turbine blades are important power elements of the aircraft engine. Under the high-speed running state of an aircraft engine, the service environment of a turbine blade is very severe, besides high-strength thermal shock, the turbine blade also needs to bear high-speed shock, airflow exciting force, alternating stress and other complex loads at extremely high temperature, so that the turbine blade can be subjected to actions of thermal corrosion, high-temperature oxidation, abrasion and the like, and therefore defects such as fine cracks, stress concentration, corrosion fatigue and the like can easily occur.

Obviously, the efficient detection method of the turbine blade is particularly important for improving the manufacturing and maintenance of the turbine blade, and an efficient detection system for the damage of the turbine blade at the present stage still belongs to the blank, so that an effective method is urgently needed to be adopted for efficient detection. As a novel nondestructive testing method, the infrared thermal imaging nondestructive testing technology is characterized in that an infrared thermal imager with better service performance is used for collecting infrared detail characteristic images after thermal excitation, and then detection analysis is carried out, so that the health state and the internal integrity of the turbine blade can be efficiently and quickly monitored.
Thermal excitation loading for infrared detection of turbine blades is achieved by means of external thermal radiation or thermal conduction. Due to the material, coating and structural characteristics of the turbine blade, the problem of uneven heat distribution on the near surface of the turbine blade can be caused, so that the collection, analysis and evaluation of the infrared thermal imaging system on the characteristic image of the turbine blade can be directly influenced, and the detection efficiency and quality of the turbine blade are finally reduced. Therefore, by developing a turbine blade defect infrared detection system fusing a constant-temperature heating box, a uniform temperature field is established by the constant-temperature heating box to thermally excite the turbine blade, so that the uniform heating and heating efficiency of the turbine blade can be greatly improved; the detection efficiency and the automation degree in the manufacturing and maintenance processes are improved, and the influence of uncertain factors such as human and experience on the detection result is reduced; and tracking, analyzing and safety evaluating are carried out according to the data obtained by detection, so that the airworthiness of the aircraft engine is improved and the safe operation of the engine is ensured.
