Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to an engine turbine blade wear detection device. Background Art

[0002] The aircraft engine is the heart of the aircraft, and the turbine blades are the key hot end components of the aircraft engine. The turbine blades in the engine have the important task of converting the thermal energy of high-temperature combustion gas into mechanical energy. Their working performance directly affects the thrust, efficiency and reliability of the engine. In modern high-performance aircraft engines, turbine blades need to work stably under extreme conditions of high temperature, high pressure and high-speed rotation. Any slight fault or wear may lead to a decline in engine performance and even cause serious flight safety accidents. Therefore, the degree of blade wear must be regularly inspected.

[0003] With the continuous development of aircraft engine technology, higher requirements are placed on the accuracy and reliability of turbine blade wear detection. Modern aircraft engines pursue higher performance and longer service life, which requires the ability to accurately detect tiny wear changes on the blade surface and accurately assess the impact of wear on engine performance. For new high-performance aircraft engines, wear detection devices are required to be able to detect micron-level scratches and pits on the blade surface and predict the remaining service life of the engine based on the test results, so that maintenance and overhaul work can be arranged in a timely manner to ensure flight safety.

[0004] One of the traditional inspection methods is to regularly disassemble the engine and then conduct manual visual inspection and measurement of the turbine blades. Although this method can more intuitively observe the wear of the blades, it has many disadvantages. First, disassembling the engine is a complex, time-consuming and costly process that requires a lot of manpower, material resources and downtime, seriously affecting the normal operation and utilization efficiency of the aircraft. For a large civil airliner, an engine disassembly inspection may take days or even weeks. During this period, the aircraft cannot perform flight missions, causing huge economic losses. Secondly, the accuracy and reliability of manual visual inspections largely rely on the experience and skill level of the inspectors, and are prone to missed inspections or misjudgments.
