摘　　要：采用英国商用流体系统仿真软件Flowmaster,对某型航空发动机滑油系统进行仿真建模,基于传热学的基本原理,对Flowmaster软件进行二次开发,模拟真实滑油箱边界条件,分析了在飞机飞行包线工况下,飞机滑油供油、回油温度变化趋势,将仿真结果与飞行试验数据对比,两者基本一致,表明系统模型准确可靠,这一建模思路和分析方法,对后续飞机滑油系统热负荷分析具有很高工程指导价值。The British commercial fluid system simulation software Flowmaster is used to model a certain type of aircraft engine oil system,based on the basic principles of heat transfer,the Flowmaster software is re-developed to simulate the real oil tank boundary conditions and analyze the flight in the aircraft.Under the envelope condition,the oil supply and return oil temperature change trend of the aircraft,the simulation results and flight test data are basically consistent,indicating that the system model is accurate and reliable,the modeling ideas and analysis methods,for subsequent aircraft oil system thermal load analysis has high engineering guidance value.
