中文摘要:

为了评估弹用涡喷/涡扇发动机的系统效能，采用分层理论构建了一套完整的弹用涡喷/涡扇发动机系统效能评估指标体系以及系统效能评估模型。从可用性、可信性和固有能力等3方面对弹用涡喷/涡扇发动机系统效能体系进行表征，采用X个小项体现3方面的指标，并采用分层理论确定不同指标对发动机效能的影响权重，建立弹用涡喷/涡扇发动机系统效能的评估模型。对现有的8种弹用涡喷/涡扇发动机进行效能定量评估和对比分析。结果表明：涡扇发动机的性能高于涡喷发动机的，推重比和燃油经济性是影响固有能力的重要因素，验证了模型的有效性和可行性。该研究可为未来弹用涡喷/涡扇发动机的新研和改进改型提供了有力的决策支撑。

英文摘要:

In order to evaluate the system effectiveness of missile turbojet/turbofan engines, a complete set of missile turbojet/turbofan engine system effectiveness evaluation index system and system effectiveness evaluation model were constructed in a hierarchical theory. The system effectiveness of missile turbojet/turbofan engines was characterized by three aspects: availability, dependability, and capability, X sub-items were used to reflect the indexes of the three aspects, Hierarchy theory was used to determine the influence weights of different indexes to the engine effectiveness, and the model for missile turbojet/turbofan engine system effectiveness evaluation was established. Quantitative evaluation and comparative analysis of the effectiveness of 8 existing turbojet/turbofan engines were conducted. The results show that the effectiveness of the turbofan engine is greater than that of the turbojet engine, the thrust to weight ratio and fuel economy are important factors affecting capability, verifying the effectiveness and feasibility of the model. This study can provide strong decision support for future new programs and improvement programs for missile turbojet/turbofan engines.
