DETECTION AND EVALUATION OF INTERFACE SEPARATIONS IN ROCKET MOTORS

Abstract

Computations based upon the geometry of a rocket motor and the x-ray absorption coefficients of the materials indicated the feasibility of detecting interface separations in rocket motors even when the radial dimension of the unbonded area is as small as 0.001 in. These conclusions were amply verified by experiments. Tangential radiography of interface areas in rocket motors thus provides a basis upon which to develop an in-process and end-product inspection.
