再入式飞行器端帽结构的设计必须考虑该结构在穿越和返回大气层时,大气与结构表面摩擦引起的热蚀问题,同时也必须考虑由于内外壁温度梯度引起的热应力破坏问题,因此对这部分结构进行精确的力学分析是非常重要的。这部分结构常采用石墨材料或碳/碳材料,这些材料具有与一般材料不 The design of the re-entry end cap structure must take into account the thermal erosion caused by friction between the atmosphere and the structure when the structure crosses and returns to the atmosphere, and must also consider the thermal stress damage caused by the temperature gradients of the inner and outer walls. Part of the structure is very important for accurate mechanical analysis. This part of the structure often uses graphite or carbon/carbon materials. These materials have no
