射线照相检测固体发动机装药质量时,是将缺陷的三维尺寸投影到两维平面的胶片上,难以对缺陷尺寸的精确测量和深度的准确定位。射线实时成像的检测原理虽与其大致相同,但可充分利用其动态观察和较先进的图像处理技术,使其检测准确性大大提高。利用固体发动机在转台上的旋转,在切向照相对,使其界面脱粘检出率大大提高;准确测定缺陷的最大尺寸和缺陷间的最短距离;利于判断缺陷性质;利用固体发动机的不停转动,使其裂纹的检出率也大大提高;可以实时观察和记录固体发动机点火试验的全过程,利用测定固体发动机各种性能,便于分析固体发动机点火失败原因。
Radiographic detection of solid engine charge quality, the defect is the three-dimensional projection of the two-dimensional film on the plane, it is difficult to accurately measure the size of the defect and the depth of accurate positioning. Although the detection principle of ray real-time imaging is generally the same, it can make full use of its dynamic observation and more advanced image processing techniques to greatly improve the detection accuracy. The use of solid engine rotation on the turntable, the tangential camera, the interface debonding detection rate greatly improved; the maximum size of the defect and the shortest distance between the defect; help determine the nature of the defect; the use of solid engine non-stop The crack detection rate is greatly improved. The whole process of solid-state engine ignition test can be observed and recorded in real time. The solid-engine engine performance can be easily measured by analyzing various properties of the solid-state engine so as to analyze the reason of the failure of the solid-state engine ignition.
