The Method of Locating Defects for SRM Radiography

摘要: 针对固体火箭发动机界面脱粘和药柱内缺陷的定位难题，以视差法为基础，提出了推进剂内部缺陷定位的平移二次成像法和旋转二次成像法，并给出了计算公式。依据射线照相几何原理，创造性提出了缺陷定位的几何作图法，该方法简单、实用，可很好地应用于工程实际。

Abstract: This paper gives some locating methods of interface debonding and propellant defects in SRM radiography. On basis of parallax, the translational deuble-radiography and the rotating deuble-radiography which are used to locating propellant defects are presented, the calculation formulae are derived. The geometrical plotting method based on radiographic geometry principle is put forward creatively，which is brief and practical, can be used it the practical engineering.
