The Method of Locating Defects for SRM Radiography

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.
