Abstract

The invention relates to a rotary baffle distortion device for a compressor distortion test. The rotary baffle distortion device comprises a motor assembly, a coding assembly, a transmission assembly,a baffle assembly, a distortion casing assembly and an adapter casing assembly, wherein the distortion casing assembly is connected to an air inlet section of a test piece, the adapter casing assembly is connected with a test bench bell mouth, the baffle assembly is located between the distortion casing assembly and the adapter casing assembly, the motor assembly is mounted on the distortion casing assembly and connected to the baffle assembly through the transmission assembly to control the baffle assembly to rotate circumferentially, and the coding assembly is connected to the motor assembly to measure output information of the motor assembly. According to the rotary baffle distortion devic, different angular positions of a rotary distortion baffle and the inlet of a compressor can be realized through the rotary angular position in a test, and the angular inlet and outlet field parameters with high resolution can be obtained.

Description

technical field [0001] The application belongs to the technical field of aero-engine testing, and in particular relates to a rotating baffle distortion device used in a compressor distortion test. Background technique [0002] Compressors often encounter inlet pressure distortion during actual use. In order to accurately evaluate the degree of compressor deviation from design conditions, it is necessary to carry out related inlet distortion tests. [0003] At present, the commonly used method for the intake pressure distortion test is to use the plug-in type distortion simulation device to obtain the distortion condition at the compressor inlet. The existing plug-in type simulation device uses a fixed baffle device. The circumferential position of the inlet is relatively fixed, and the angular position adjustment of the baffle cannot be realized in a driving test, and limited by the number of inlet and outlet meters, only part of the inlet and outlet field parameters (pressu...
