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 & ablative liner and Propellant & 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 inteal details of rocket motor are highlighted.
