Technical Problem

[0007]而在使用性能评估中，部件法需要基于发动机部件模型通过确定各部件共同工作点然后再计算发动机推力和耗油率，而现有的模型大多是基于设计参数所确定的，尽管会有很多修正方法会补偿制造公差、装配公差以及飞行的性能衰退带来的偏离，但如前述所说，这种以设计作为参考来进行性能评估的方法离实际难免有些差距，因而精度不够准确

Benefits of technology

[0044]1、本发明的用于航空发动机/燃气轮机的性能评估方法，主要是一种机群性能排序方法，基于一种航空发动机数字工程模型M完成，其基于航空发动机类型和实际工作匹配关系而构建，与航空发动机物理结构一一对应，具有更好的模型精度，性能评估准确度较传统方法更优，可以提高现有航空发动机/内燃机使用性能优劣的评估精度。

Abstract

The present application belongs to the technical field of performance evaluation of aero-engines and gas turbines, and particularly relates to a digital method for performance evaluation of aero-engines and gas turbines. The specific technical scheme is as follows: training m machine digital engineering models Mk, establishing m standard proofreading model groups, substituting the test data of a conventional machine into the m digital engineering models Mk, performing digital experiments, and comparing the digital experiment results of the conventional machine with the test data. The evaluation accuracy of the existing aero-engine / IC engine performance can be improved, a digital evaluation system can be built through the existing digital intelligent evaluation method, and the performance evaluation system and standards of the aero-engine / IC engine can be enriched and improved.
