Feasibility of Rocket Motor Insulation Inspection Using Infrared Radiation

Abstract

Insulated, thin-wall motor cases have as a potential failure mode the burnthrough of the motor case wall resulting from a defective liner. The objective of this investigation was to determine the feasibility of the use of infrared radiation as a means of non-destructive examination of an insulated motor case in order to detect a potentially defective liner. A relatively inexpensive infrared inspection system was designed and assembled which demonstrated that it is possible to detect cracks and density variations in the insulation of rocket motor cases.
