Abstract
Usually, disbonds on solid rocket motors are examined by tangential radiography. The motor is rotated around its axis and radiographs are taken at video rate on the border of the motor. Due to the high attenuation of X-rays through the motor, the signal-to-noise ratio of the delamination is very poor. On a single radiograph, even large defect are difficult to detect. Usually, when a defect is detected, the motor rotation is stopped and the photon noise is reduced by summing a lot of radiographs at the same orientation.
