A STUDY OF MEASURING FINE AP PARTICLE SIZE WITH AN OPEICAL TRANSMISSION INSTRUMENT

In the solid rocket motor propellant, the fine AP (ammonium perchlorate) particle size has been generally measured by a sedimentation method, which has a disadvantage of long measuring period and is time and labour-consuming. The application of an optical transmission instrument for measuring the Fine AP particle size can greatly shorten measuring time, be time and labour-saving and eliminate the human error in data processing. The pape gives out the accuracy of the fine AP particle size measured with an optical transmission instrument, as well as the relation between the optical transmission and the sedimentation for measuring the fine AP particle size. In the large solid motor grain manufacture, the application of an optical transmission instrument for measuring the fine AP particle size can control the propellant burning rate so as to ensure quality of the motor product.
