Design of Instrumentation System of Aeroengine Can Combustor Test

Abstract: In order to meet the requirements of new combustion tests, a distributed measurement and control system which based on Ethernet technology was proposed and designed for the characteristic of can combustor tester in the test of aeroengine combustion chambers. The overall design scheme of the system are described in detail. The detailed design process of the system was researched and analyzed in hardware and software aspects, then the measurement uncertainty was analyzed. At present, the system has been Debugged and verified by tests before experiment, and has successfully completed multiple can combustor tasks. The result shows that the system has high reliability, stability, and strong versatility, and can satisfy the test and control requirements.
