摘　　要：通过分析目前航空发动机控制系统故障检测仿真软件缺乏通用性、模块化的问题,将发动机建模、故障检测和组件开发技术相结合,提出并设计了航空发动机控制系统故障检测仿真平台,分析该平台的设计目标、软件总体架构与主要功能。针对某型涡扇发动机为研究对象,给出传感器与执行机构典型故障的模式分析和检测逻辑,在飞行包线设计点进行仿真计算。实践表明该平台能够准确实时仿真发动机控制系统典型故障,具有功能可靠、易扩展、工程化程度高的特点。Due to the lack of commonality and modularization in fault detection of aero engine control system,a fault detection simulation platform for aero engine control system is proposed and designed in this paper by combining modeling,fault detection and component development technologies.The design objective,software architecture and main functions are analyzed.Using a turbofan engine control system as the object of study,the sensor and actuator＇s typical faults are given and the design points performances in flight envelope are simulated.The application shows that the platform can accurately simulate aero engine fault in real time and is reliable and flexible.
