TEST DEVICE FOR AIRCRAFT ENGINE COMPRESSOR Russian patent published in 2012 - IPC G01M15/14 

FIELD: test equipment.

SUBSTANCE: invention refers to test device for aircraft engine compressor. The essence of the invention consists in manufacture of the test device of the main stationary internal structure, which protrudes on cantilevers out of the wall of the test bench and contains drive shaft of tested compressor, as well as of movable replaceable external structural modules that can be aligned in relation to each other by means of connected optic device, of replaceable internal elements for direction of air flow and reduction of noise level, as well as of replaceable measuring devices connected to modular telemetering unit for determination of technical characteristics and aerodynamic and acoustic parameters dependent on compressor and internal elements.

EFFECT: test device allows recording certain data at relatively low structural flows, which are related to the compressor design and to internal elements located behind it in the flow passage, and based on which the conclusions can be made on reduction of noise level, optimum aerodynamic structure and improvement of technical characteristics.
