为发挥航空发动机燃油的最大使用效益,充分利用燃油对发动机滑油及飞机交流发电机(IDG)滑油的冷却作用,利用多种分析方法对某型航空发动机燃油温升特性进行研究,给出了发动机典型工作状态下的燃油温升特性,并与试验结果进行对比。结果表明提出的分析方法能够有效的计算航空发动机各工作状态下的燃油温升特性。
In order to give full play to the maximum utilization efficiency of aero-engine fuel and to make full use of the cooling effect of the fuel on the engine oil and the IDG oil, a variety of analytical methods are used to study the temperature rise characteristics of a certain type of aero-engine fuel, The typical temperature of the engine fuel temperature characteristics, and compared with the test results. The results show that the proposed analytical method can effectively calculate the temperature rise characteristics of the fuel under all operating conditions of the aero-engine.
