Ltd.10.18063/EIR.v4i4.1972ArticleDesign and Exploration of a Virtual Simulation Experiment Project for Typical Fault Analysis in Aviation Engineshttps://artdesignp.com/journal/EIR/4/4/10.18063/EIR.v4i4.1972ChenJian,LiuMingchao,ZhuShouxi2026442026-04-26Aviation engines are classic examples of complex thermodynamic systems. They operate under conditions of high temperature, high pressure, and high rotational speed. As a result, real-world fault testing is characterized by high cost, high risk, limited data accessibility, restricted operation, and poor reproducibility. To address these problems, this paper presents a systematic and hierarchical design for a Virtual Simulation Experiment Project on Typical Aviation Engine Fault Analysis. Starting from the basic operating principles of turbojet and turbofan engines, the project systematically discusses several typical failure modes, including compressor stall and surge, fuel supply anomalies, lubrication system malfunctions, rotor imbalance, blade damage, foreign object ingestion, and sensor drift. A virtual experiment framework is established based on the teaching sequence of structural analysis → parameter monitoring → fault injection → mechanism investigation → diagnostic decision-making → report evaluation. On this basis, the paper proposes an experimental approach that integrates 3D visualization, thermodynamic cycle models, fault rule libraries, parameter trend simulation, and closed-loop learning evaluation. Traditional aviation engine testing has obvious limitations in visualizing internal processes and simulating hazardous or complex operating conditions. Therefore, this virtual simulation project transforms engine fault mechanisms, maintenance procedures, testing methods, and health management concepts into interactive experimental tasks. By integrating engine theory, control systems, and testing technology, the project provides a safe, cost-effective, repeatable, and evaluable platform for aviation engine fault analysis teaching.Aero-engine, Typical faults, Virtual simulation, Fault diagnosis, Air path analysis, Experimental teaching
