AI Technical Summary

Technical Problem

In ground tests of aero-engines, existing technologies cannot effectively simulate the operation of intake and exhaust dampers and accurately transmit feedback signals, which limits the reliability and efficiency of test results. Existing solutions either shield fault signals or rely on physical tests, which have their own defects.

Method used

The system employs a digital control system, including an operation panel, a digital simulator for the intake and exhaust dampers, an aero-engine controller, and a host computer. Through realistic logic processing and time-delay signal simulation, it achieves dynamic response simulation of the intake and exhaust dampers. Closed-loop control and real-time fault monitoring are used to ensure accurate signal transmission and processing.

Benefits of technology

It achieves efficient and accurate simulation without the need for physical damper hardware, ensuring the reliability and accuracy of test data, shortening the test cycle, reducing costs, and meeting the needs of rapid iteration of aero-engines.
