Problems solved by technology

However, because the air film holes of the blade are distributed on the curved surface of the blade body, they are three-dimensional curved surface holes in space, and the hole diameter is small. Not only is the processing process difficult, but how to achieve accurate detection has always been a technical problem in the industry.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to a high-precision detection device and a detection method for an air film hole in an aero-engine blade. Background technique [0002] As the sole source of aircraft flight power, the aeroengine is the core unit of the aircraft. Aeroengines are based on aerodynamics, starting from fan guide vanes, to low-pressure static, rotor blades, high-pressure static, rotor blades, high-pressure guide turbines and turbine blades, low-pressure turbine guides and turbine blades, etc., relying on a large number of different geometric shapes, sizes and functions. The blades enable the engine to continuously generate high-pressure gas, and the high-temperature and high-pressure gas is carried by the high-turbine blades to drive the turbine unit to work, and finally converted into aircraft flight power. [0003] Modern advanced aero-engines generally use small-hole film-cooled turbine blades t...
