摘    要:导弹等高速飞行器广泛采用轻质材料进行热防护,但实际使用的轻质防热材料由于在密度、质量、工艺、生产批次等多方面的原因,厂家提供的非连续表征的离散式材料导热系数,与非线性连续变化的实际热参数之间存在一定差别.建立轻质防热材料高温导热系数测量装置,通过试验得到轻质高温陶瓷隔热材料导热系数与温度之间的非线性关系,为提高数值计算...

关 键 词:热防护设计  轻质材料  导热系数  数值模拟  气动热试验

Abstract:Lightweight materials are widely used in missiles and other high-speed aircrafts for thermal protection.As the actual lightweight heat-resistant materials differ in density,quality,technology,production batches and other aspects,the piecewise discrete thermal conductivities provided by the manufacturer are normally quite different from actual values of the materials.In this paper,in order to provide reliable thermal conductivities suitable for accurate numerical simulation,a high-temperature thermal conduct...
Keywords:thermal protection design  lightweight material  thermal conductivity  numerical simulation  thermal aerodynamic test
