| 摘 要： | 提出了一种利用发动机部件特性计算双转子发动机风车特性的方法 ,主要用于发动机方案论证阶段的风车特性的计算。为解决高、低转子匹配问题 ,在计算高压转子时 ,把它当成单转子发动机来计算 ;在计算低压转子时 ,则把高压转子看成是低压转子的一个阻力元件。以某型发动机为例 ,计算出风车特性基本符合试验结果

| Abstract: | The operation of a twin spool turbojet under windmilling condition is analyzed and the windmilling characteristics are derived.The calculation method is based on theoretical analysis and experimental data. Using characteristics of components, including the compressor, the turbine and the combustion chamber, the windmilling characteristics are obtained. In calculating the high pressure rotor, the method is the same as that of the single rotor turbojet engine. When calculating low pressure rotor,the high pressure rotor is taken as a resistant component of the low pressure rotor.An example of the application of the method is presented, which shows good. agreement between the prediction and experimental data |
