航空发动机压气机衰退对动态性能影响
Influence of Degraded Compressor on Aeroengine Dynamic Performance
摘要
Abstract
Aero-engine degradation is an inevitable phenomenon that significantly impacts the performance,fuel con-sumption,and emissions of aero-engines.To ensure the safe operation of aero-engines and to conduct subsequent health status assessments of the engines,research on the impact of compressor component degradation on the dynamic perfor-mance of aero-engines is conducted.Focusing on the performance degradation issue of aero-engines and taking the com-pressor as the research object,a health parameter module that can simulate the degradation state of the compressor is in-troduced based on the component-level aero-engine model.A performance parameter degradation propagation model for the compressor is established to quantitatively simulate the performance degradation process of the compressor within the aero-engine model.Simulations are conducted under different degradation states of the compressor to obtain the variation patterns and characteristics of engine performance parameters in both steady-state and dynamic processes.To describe the performance and health status of the engine,a performance degradation status index for the aero-engine compressor components is proposed.The concept of the compressor performance degradation status index is introduced,and the variation patterns of this index with the degree of degradation in the dynamic process are analyzed,providing a reference for subsequent health status assessments of the compressor.关键词
