Computer Tomography of Thermal Batteries and Other Closed Systems

Abstract

Under a preliminary testing task assignment of the Advanced Development of X-ray Computed Tomography Applications program, computed tomography (CT) has been applied to several types of closed system components. For this task, closed system components were defined as components which were closed structurally such that the interior could not be inspected except by penetrating radiation. The primary testing emphasis was with thermal batteries. The units are hermetically sealed with a number of internal components and materials whose proper assembly and orientation is essential for successful operation. In addition to thermal batteries, several other mechanical and electromechanical closed systems were examined, including: missile and rocket launch secure and enable systems, and aircraft mechanical actuators and drive subsystems.
