ACMS客户化编程技术在发动机故障诊断上的应用

Application of ACMS Customization Programming Technology in Fault Diagnosis of Airliner Engine

摘要:

发动机系统由于其内部结构复杂,工作环境恶劣,极易发生故障,而发动机在设计之初又无法实现对所有故障的准确探测和隔离；为了解决飞机投入运营后对发动机复杂故障的探测问题,文章以B737-700飞机的液压机械组件故障探测为例,提出利用机载的ACMS客户化编程技术,通过自定义相应的故障诊断报文来提高发动机的健康监控水平;实践证明,客户化ACMS编程技术能够极大地提高航空公司对发动机的故障诊断水平,方便航空公司日常的运营和维护工作,最终提高飞机的利用率。

Abstract:

Due to the complex structure and poor working condition,engines’ faults are more likely to occur. But during the design process of engines,it is impossible to detect and isolate all of the faults or failures. So,in order to solve the detection issue of complicated engine faults,taking hydromechanical unit of B737-700 as an example,this article intend to propose the application of ACMS customized programming technolgy,which can enable airliners to define grand new reports by themselves to detect the corresponding faults.Then the engine health monitoring level will be raised. Practices has proved that the custmized programming funciton will enhance the fault diagnosis level of engines,faciliate the airliners’ operation and maintenance process,and finally promote the flleet utilization.
