Research on Real-time Process Monitoring Technology and System for High-speed Turbopump

摘要：

Turbopump is a high-fault-rate component in Liquid Rocket Engine (LRE).The research on real-time process monitoring technology and system for turbopump is vital to increase the reliability and safety of LRE.In this paper,three real-time process monitoring algorithms for turbopump were studied firstly,on the basis of monitoring parameters selection and multiple domain feature extraction.Then,the real-time monitoring system realized by means of PXI (PCI extensions for Instrumentation) controller was introduced.And,aiming at the shortage of the previous system,the real-time process monitoring system based on DSP (Digital Signal Processor) for turbopump was studied to realize higher computing speed,which could conduce to extract multiple domain features and run manifold real-time monitoring algorithms.The new system could also satisfy the small-sized requirement in engine flying state.
