虚拟仪器技术在航空发动机智能检测中的应用

Application of Virtual Instrument Technology to Intelligent Aero-engine Testing

利用NI公司的LabW indows/CVI虚拟仪器作为开发平台,设计了一套适用于某型航空发动机地面试车的智能检测系统。实际检测结果表明:该系统较真实地反映了被测航空发动机的试车参数、工作状态及试车曲线。与传统的检测方法相比,既节省了成本,又提高了检测效率。

Using LabWindows/CVI developed by National Instrument Company as a development tool, an intelligent testing system was designed for the ground running test for an aero-engine. The results from the practical test using the system showed that this system accurately indicated the parameters, operating modes and test curves for the engine in the running test. Compared with the conventional testing method, it not only reduced the cost, but also improved the testing efficiency.
