The Study of Heat-Scan Infrared NDT to the Inspection for Adhesion of Propellant of Rocket Motor to the Envelope,

Abstract

This paper briefly describes the basic principles of the heat-scan infrared NDT and introduces the method and results of the utilization of Type HT-1 Heat-scan Infrared NDT Machine to the inspection for adhesion of the solid propellant of the rocket motor to the envelope. The selection of inspection parameters and the relations among them are analyzed and discussed, and the methods for defect signal recognition, defect location and semiquantitative computations are proposed herein. This method can conveniently and rapidly evaluate the quality conditions of propellant to the envelope and has a guiding significance for the technology of propellant production.
