摘　　要：根据弹用涡扇发动机的研制特点,提出了弹用涡扇发动机虚拟试验平台的总体方案,根据总体方案构建了平台的总体框架;以平台的有代表性的子平台为对象,如弹用涡扇发动机总体性能虚拟试验子平台、涡轮气动虚拟试验子平台,进行了平台的研究和搭建;为了对发动机性能进行评估,也研制了一套总体性能故障诊断系统;文中通过应用实例,验证了子平台的虚拟试验结果和故障诊断系统,表明了子平台和故障诊断系统的可用性和有效性。Based on the characteristic of developing missile- used turbofan engines, the total scenario for the virtual experiment platform of missile- used turbofan engines is provided here. According to the scenario, two sub platforms in the platform, the turhin component and the overall performance, are studied and constructed. In addition, a set of fault diaganosis system for the overall performance of missile-- used turbofan engines is developed to evaluate engine perfor - manee. Through the application of the above snh- platforms and fauh diaganosis system into the development of a certain type of nlissile-- used turbofan engine, the validity and applicabilityof the platform are verified.
