摘　　要：目前航空发动机性能模型在试飞领域的深度应用已成为数字化试飞背景下的热点,对飞行试验过程中试验点的策划与组织、风险识别与分析、试飞结果辅助分析与评估等工作具有重要的价值和意义。基于一种通用的面向对象仿真框架搭建某型双转子混排涡扇发动机的性能模型;为了提高模型的计算精度,提出一种基于实际共同工作线的旋转部件特性修正方法;通过模型在不同工况下的稳态性能及瞬态性能求解,给出该型发动机在包线范围内的性能特性和海平面标准大气环境下的推力瞬变特性。结果表明:该模型在不同工况下整机性能的计算值与实测值偏差小于3%。At present,the in-depth application of aero-engine performance model in the field of test flight has be⁃come a hot spot under the background of digital test flight,which is of great value and significance to the planning and organization of test sites in the process of flight test,risk identification and analysis,and auxiliary analysis and evaluation of test flight results.The performance model of a two-spool mixed flow turbofan engine is constructed based on a general object-oriented simulation architecture.In order to improve the model prediction accuracy,a cor⁃rection method of the characteristics of rotating components is proposed based on the common operation line.The steady performance and transient performance of the model under different working conditions are solved,and the performance characteristics of the engine in the flight envelope and the thrust transient characteristics of the sea level standard atmospheric environment are given.The results show that,compared with the measured value,the cal⁃culation deviation of the model under different working conditions is less than 3%.
