Testing of the failure of a solid rocket propellant with tomography methods

The paper presents the proposition of non destructive testing (NDT) of the rocket engine propellant rod. It presents the actual state of the research and perspectives of its continuation. In this research, capacitance tomogra phy system was used. The method was compared with the radiological and radi ometric methods. Experiments were done with the use of solid propellant wit h different pyrotechnic mass and artificial defects incorporated. Authors s uggest a new method of differential tomography.
