【摘要】 对火箭和导弹的测试是航天试验的重要组成部分,射线无损检测技术,尤其是大型工业CT是一种有效的手段,由于大型火箭和导弹的体积与重量都十分巨大,而且加速器和探测系统都将很笨重,所以,提出一种新颖有效的螺旋CT扫描方式,讨论了大型导弹CT检测的基本原理和其中重要的辐射物理问题,在系统分析的基础上,给出了系统的总体设计方案。更多还原

【Abstract】 The examination of rockets and missiles is playing an important role in the spaceflight experimentation. The technique of nondestructive examination with X rays, especially the large industrial CT. is an effective method. Because the volume and weight of large rockets and missiles is very huge, and also the system of the accelerator and detectors will be very heavy, an original and effective spiral CT scan method is devised. The fundamental theory and the radiation physics problems of large missile inspection system are discussed in this paper. Based on the system analysis, this paper also gives the integrity design of this system.更多还原
