航空发动机作为飞机的核心部件，一旦出现故障，其飞行过程中的安全性和可靠性就会降低。这些故障会导致不可预测的后果。因此，有必要研究如何对发动机的故障进行建模。基于Simulink软件，根据气动热力学方程导出的航空发动机数学模型建立了航空发动机仿真模型。本文对航空发动机仿真模型进行了各种典型故障的仿真，仿真结果表明，所设计的模型能够正确获取发动机气动热力学输出参数和常见故障数据，验证了模型的合理性和有效性。仿真生成器为发动机建模提供了可视化工具，为航空发动机故障诊断和预测提供数据支持。
As a core component of an aircraft, once the aeroengine occurs faults, its safety and reliability reduce during the flight. These faults cause unpredictable consequences. Therefore, it is necessary to study how to model the faults of the engine. Based on Simulink software, aeroengine simulation model is established from aeroengine mathematical model which can be derived from aerothermodynamics equations. This paper Simulates various typical faults to aeroengine simulation model, the simulation results show that the designed model can correctly obtain the engine aerothermodynamics export parameters and common faults data, verifying the rationality and effectiveness of the model. The simulation generator provides a visual tool for engine modeling, and supplies data support for aeroengine fault diagnosis and prediction.
