Abstract

The invention relates to an intelligent detection device and method for a compressor stator guide vane setting angle. A measuring and positioning tool is composed of a tool cross beam (1), supportingbases (2), a two-dimensional sliding table (3), a high-precision rotary table (4), a depth shaft (5) and positioning pins (6), wherein the two-dimensional sliding table (3) and the high-precision rotary table (4) are sequentially installed on the lower end face of the middle of the tool cross beam (1), and the depth shaft (5) is fixed to the high-precision rotary table (4); the two supporting bases (2) are located on the two sides of the tool cross beam (1) respectively, the positioning pins (6) are arranged on the supporting bases (2), and the measuring and positioning tool is fixedly placedon a to-be-detected compressor case (15) through the positioning pins (6). Detection results can be displayed in real time, detection result data storage and export functions are provided, and the defects of manual misreading, complex data recording and the like are overcome; the detection method is high in measurement precision, high in efficiency and convenient to use.

Description

technical field [0001] The invention relates to the measurement design of the vane installation angle, and provides an intelligent detection method for the installation angle of the compressor stator guide vane. Background technique [0002] In the field of aviation, the installation angle of the guide vane of the compressor stator has a great influence on the secondary flow loss of the engine, especially the installation angle of the guide vane after the assembly of the high-pressure compressor stator directly affects its energy conversion efficiency. In aero-engines, the direction of the outlet angle of the guide vanes is usually controlled to keep the angle of attack of the airflow flowing into the first-stage rotor blades at a proper position, thereby avoiding the occurrence of engine surge. Therefore, the installation angle of the blades in the casing has a great influence on the performance of the engine, and determining the change of the installation angle of the blad...
