The invention provides an engine blade intake and exhaust edge profile measuring device and measuring method. Through the two non-contact sensors, high-precision measurement data of the contour of theair inlet or outlet edge of the engine blade can be obtained at a time, and therefore the problem that contour data of the air inlet or outlet edge of the engine blade are difficult to obtain in themachining, quality detecting and repairing processes is solved.
Description
technical field [0001] The invention belongs to the technical field of measurement of complex parts, and relates to a device for measuring the profile of intake and exhaust edges of engine blades and a corresponding measurement method. Background technique [0002] In the field of aeroengines, engine blades are one of the key parts of the engine. Not only are there many types and quantities, but they also have various shapes and complex structures, which account for a considerable proportion in engine manufacturing. For engine blades, the geometric accuracy and consistency of the intake and exhaust edges have a crucial impact on the dynamic performance of the engine. Usually, the cross-sectional shape of the intake and exhaust sides of the engine blade is a circular arc or an elliptical arc. The new generation of aero-engines requires a smaller volume to obtain greater output power. The geometric dimensions of the gas edge are also getting smaller and smaller, while the acc...
