摘要
基于面向对象的软件设计思想,设计了一种灵活、通用、可靠的航空发动机仿真平台框架。将仿真平台划分成了清晰的3个层次,并在每一层下设置了相应的类模型,各层之间的数据交换灵活、高效;然后建立了标准化的部件类库,针对不同类型的发动机,可以高效地搭建起对应的发动机模型,并可兼顾稳态、过渡态和实时仿真等多种计算任务的要求。最后在该框架的基础上,建立了某型双转子混排涡扇发动机的对象模型,分别对稳态和过渡态过程进行了仿真,计算结果精度高,验证了仿真平台的有效性。
Using the objectoriented design method, a general, flexible and reliable aircraft engine perform ance simulation framework is designed. The simulation platform is divided into three layers clearly and the corresponding kind of model is established under each layer, thus the data exchanges among layers are flexible and effective. The fundament component class library is established and can be used to build differ ent aeroengine simulation models. The performance simulation framework is applied to several calculating missions including steady, transient and realtime simulations. Based on the simulation framework, a two spool mixed flow turbofan simulation model is build and its steady and transient progress are calculated. The calculation results are of high precision and verify the effectiveness of the framework.
