摘要：
The requirement and progress of aircraft engine nonlinear aerothermal-dynamic modeling technique for the surge phenomenon and rain and hail ingestion effects in special operating conditions were reviewed pursuant to airworthiness regulation. Key modeling elements for the model with the simulation capability of surge, rain ingestion and hail ingestion were proposed based on the analysis of aero-engine dynamic characteristics and transient simulation methods. Result showed that, rotor dynamics was the most important compared with volume dynamics and thermal effect. Constant flow method had high accuracy and inter-component volume method was suitable for description of the engine high frequency dynamics. Compliance demonstration model should incorporate surge, rain ingestion and hail ingestion elements based on the component-matching aerothermal-dynamic model. The analysis can support the simulation tools development based on test data and service data. © 2018, Editorial Department of Journal of Aerospace Power. All right reserved.
