Rapid Prototype Design of Health Management System for Aeroengine

In order to solve the long production cycle and high cost problems of the traditional design approach for aeroengine health management system, a kind of rapid prototype simulation design method was proposed and a rapid prototype platform based on virtual instrument and rapid prototype technology was established. A signal interface unit was designed under the application environment named Field Programmable Gate Array (FPGA) to simulate the real sensors values by the National Instrument (NI) CompactRIO. The platform can provide the windows-based real time health management software development environment, which can download health management algorithms to the platform quickly. The results show that the rapid prototype design method of health management system is effective and provides a good foundation for further research on a completely Hardware In Loop (HIL) platform. The rapid prototype platform has good practical engineering value.
