Abstract

An aero-engine test bed mounting system comprises a test bed frame, an air inlet fairing mounted on the test bed frame, a test piece mounting mechanism, a rotary measuring mechanism and an exhaust pipe. The exhaust pipe comprises an exhaust straight pipe and an expansion pipe, an air inlet cone is arranged in the air inlet fairing, and an exhaust cone is arranged in the exhaust pipe; an air pressure measuring device is arranged in the air inlet fairing, and a plurality of air pressure measuring devices are arranged in the rotary measuring mechanism; a movable connecting unit and an air inlet fairing are arranged on the mounting rack; and the test piece mounting mechanism moves through the movable connecting unit. The installation system has the advantages of real simulation environment andaccurate measurement data.

Description

technical field [0001] The invention relates to an aeroengine test device, in particular to a test bench installation system capable of testing the aerodynamic performance of the aeroengine particle separator and the flow rate caused by anti-icing. Background technique [0002] The working conditions of the aero-engine are very harsh, in the working state of high temperature, high pressure and high-speed rotation. In order to improve the performance, reliability and life of the aero-engine, it is necessary to fully grasp the temperature, pressure, corrosion, and clearance of the aero-engine under different working conditions. and stress etc. In order to master the above data, it is usually necessary to test the aero-engine on the test bench, including component and system tests, complete machine test, etc. [0003] The particle separator is an important part installed at the inlet of an aeroengine to prevent damage to engine components, increase in fuel consumption and decr...
