| 摘 要： | 应用高速桨扇试验数据与涡轴核心机估算模型相结合的方法,建立了一种快速的、能用于飞机总体方案论证阶段的开式转子发动机分析模型.它使用少量的总体参数即可估算出开式转子发动机推力与耗油率特性、质量和外形尺寸,计算速度快.通过对比模型的估算结果与文献的试验数据,证明其精度能够满足飞机总体初步方案论证的要求,可用于评估采用开式转子发动机带来的收益.

| Abstract: | A rapid analysis model of the open rotor engine,which can be used in aircraft conceptual design,was established by the combination of the test data of high speed propfan and approximate model of turboshaft.The performance,mass and size of the open rotor engine were able to be predicted quickly by this model with a small amount of input parameters.The precision of the model was validated by the experimental data from the references.The model developed in the paper can be used in the aircraft conceptual design to evaluate the benefits of using open rotor engines. |
