The geometric parameters of aero-engine blades are defined and classified. Based on the importance of precise measurement of blade geometric parameters, the complexity of profile parameters measurement and the status quo of full parameter measurement and evaluation of blade geometric characteristics, the requirements of the construction of measurement and measurement guarantee system for aero-engine blade geometric parameters are introduced in detail. A test measurement guarantee system covering the parameters of aero-engine blade geometrical characteristics is proposed, and the connotation and architecture of the system are expounded, which can provide technical support for the construction of the integrated collaborative work platform for the digital design and manufacturing of aero-engine blade parts.
