Rocket Motor is a highly complex aerospace component that consists of a metal casing, ablative liner and Propellant grain. The Rocket motor is to be inspected for various interfaces and defects such as debonds between metal casing and ablative liner and Propellant and ablative liner and delaminations in ablative liner and defects in Propellant. X-ray Radiography Testing (RT) and X-ray Computed Tomography (CT) methods are employed for identification of various interfaces and defects evaluation in rocket motor. RT could not show all the interfaces clearly whereas CT revealed all the interfaces with their boundaries clearly in a single cross-sectional image. The salient features of CT and its edge over RT in evaluation of internal details of rocket motor are highlighted. CT inspection is proved to be vital importance in revealing the internal details of all the interfaces clearly seen and the alignment of grain with respect to its web thickness, which are not possible to obtain through conventional NDE methods (RT).
