基于使用数据的航空发动机性能评估方法
Performance Evaluation Method for Aeroengines Based on Usage Data
摘要
Abstract
Based on the particle swarm optimization algorithm,a method for evaluating the perform-ance of aeroengines used in the outfield was studied.A criterion for selecting data suitable for performance calculation from massive aeroengine usage data was proposed.To address the defect of low fitness function values in traditional adaptive correction methods,a comprehensive prediction and correction method was adopted to improve the original performance evaluation method.Calculation results show that the fitness function value obtained by the improved method increases from approximately 0.85 to over 0.98,making the calculation results more credible.关键词
