基于模型的涡扇发动机性能衰减评估
Model-based Performance Degradation Evaluation for Turbofan Engine
摘要
Abstract
In order to obtain the performance degradation and degradation trend of each component in turbofan engine life cycle,sequential quadratic optimization algorithm based on engine performance calculation model and component degra-dation factors was used to optimize the performance degradation in each stage of a 300 hour long-term test engine.The calculation results show that the maximum error between the model calculation results and the experimental measurement results is 4.33％,and the error of most parameters is within±2.0％.In the earlier stage of long-term test,the high-pressure turbine and compressor decay,the low-pressure turbine and fan components decay faster in the later stage and the compressor and low-pressure turbine decay most seriously after 300 hours test.关键词
