An intelligent management system for the use history of aero-engine high-altitude cabin test bench

Abstract

The invention provides an aero-engine high-altitude cabin test bench operation process intelligent management system, which includes a sensor unit, a data collection module and a communication module. The sensor unit is connected to the data receiving module through a bus, and the input end of the communication module is connected to the data collection module through the bus. The output end is connected to the aero-engine high-altitude cabin test management system through optical fiber. The sensor unit transmits the collected history data to the data collection module through the bus. The data collection module compares the accumulated service life of each parameter collected by the sensor with the preset value. Service life, over-limit alarm of service life, by comparing the instantaneous sampling value of each parameter collected by the sensor with the preset threshold value, over-limit alarm of instantaneous sampling state, through real-time monitoring of two aspects, it can be more accurate and timely. It provides early warning prompts, reduces the fatigue risk of the test bench, and provides bench monitoring data support for the high-altitude cabin test of aero-engine.

Description

technical field [0001] The invention relates to the technical field of aero-engines, in particular to an intelligent management system for the use history of an aero-engine high-altitude cabin test bench. Background technique [0002] The aero-engine high-altitude cabin test bench is an indispensable test equipment during the high-altitude simulation test of the engine. In the high-altitude simulation test of the aero-engine, the engine is installed on the test bench, and the engine is in the high-altitude cabin to simulate the flight from low altitude to high altitude The state changes of the mid-engine operation, which are subjected to a wide range of load cycles during operation, especially the huge changes in all thrust, heat radiation and vibration of the aero-engine from idle to afterburner and full afterburner flight. , the test bench is prone to fatigue, which seriously affects the safety of the engine test. Therefore, it is necessary to design an intelligent managem...

Problems solved by technology

[0002] The aero-engine high-altitude cabin test bench is an essential test equipment for the high-altitude simulation test of the engine. During the high-altitude simulation test of the aero-engine, the engine is installed on the test bench, and the engine is simulated from low altitude to high altitude flight in the high-altitude cabin. The state change of the medium engine operation, which is subjected to a wide range of various load cycles during operation, especially the huge changes in all thrust, heat radiation and vibration of the aeroengine in the state of the aeroengine from idling to afterburner and full afterburner flight , the test bench is prone to fatigue, which seriously affects the safety of the engine test run, so it is necessary to design an intelligent management system for the use history of the aero-engine high-altitude cabin test bench
