【Abstract】 This paper introduces basic principles of heat-scan infrared NDT and desribes the method and the results of the appliations of the Heat-sean Irfrared NDT Machine Type HT-1 to the inspectin for adhesion of the propellant of the rocket motor to the envelop. The selection of the testing parameters and the relations among them are analyzed and discussed. The methods of recognition, location and evaluation of the defect signal are proposed. This method can conveniently and rapidly evaluate the quality of the adhesion of the propellant to the envelop and has a guiding significance for the technology of propellant production.更多还原
