有效载荷推进舱上的复合材料层间粘接密度低的部位是航天飞机第10次飞行时该推进舱发生两次故障的主要可疑之处。调查小组采用计算机处理的层析X射线摄影法筛选发动机喷管出口锥,来调查有效载荷推进舱的两次故障。据认为,所探测到的低密度的粘接处足 The areas of low bonding density of the composite material on the propulsion pods are the main suspicion of two failures of the pods on the tenth flight of the space shuttle. The investigation team used computerized tomography to screen the engine nozzle exit cone to investigate two failures of the payload propulsion module. It is believed that the detected low-density bonds are sufficient
