Research of virtual surging sensor for X preponderant aeroengine

The surging sensor of X preponderant aeroengine is one of the most important components of EEC (electronic engine controller),so the research of how to simulate surging sensor is important for the simulation of surging experiment and digital research of EEC.Through the research of inner mechanism of surging sensor for X preponderant aeroengine,it's characteristic and function is mastered.Then,according to the theory of virtual instrument (VI),the design of imaginary sensor is discussed from the aspect of hardware and software.The finding indicates that the imaginary sensor can replace the former surging sensor and it has many advantages such as low cost,high testing reliability,high adjusting accuracy.
