Abstract:
In order to simulate the combustion process of low temperature sensitivity coated propellants in mixed charge, the surface of coated propellants collected in intercepted combustion experiments at room temperature is observed with a 3D video microscope. The combustion process is analyzed. On the basis of intercepted combustion experiments, laws of coating perforations affected by charge conditions such as ignition pressure, the mass ratio of main charge propellants to coated propellants, c harge density are studied. The model of coating perforation laws and its calculation method in combustion simulation are established. The model is verified by closed bomb experiments and interior ballistic experiments. The results show that the calculated p-t curves are coincident well with that of experiments.
