| 摘 要： | 现代民用飞机机身结构大量采用复合材料,但因其遇到高温时会变软,耐热性较差,这就对复合材料周围的环境温度提出了新的要求。以某型飞机的空调组件安装区域进行温度场CFD计算,分析了安装区内的高温部件对机身复合材料结构的影响。为了防止机身复合材料被高温部件烫伤,在高温部件的上方安装隔热板同时进行局部通风冷却,并对相应的工况进行CFD计算对比。

| Abstract: | A large number of composite materials are used in aircraft structure, which could become weak in high temperature condition. A computational fluid dynamics (CFD), steady state computational model of the aircraft high temperature area was used to investigate and analyzed. Thermal-protective coating and ventilating is used to protect composite material parts from being heated. |

| Keywords: | composite material high temperature temperature field cooling |
