| Abstract: | In this paper, the observation of the burning processes of AP-PU sandwiches with and without CaCO3 by means of the loser-shadow high speed cinephotomi-crography, analysis of burning surface of some samples with scanning electron microscope, and examination of the burning surface of AP-PU solid composite propellant by X-ray photoelectron spectroscopy are discribed. Based on the above experiments, a knid of mechanism of the effects of CaCO3 upon AP burning rates has been proposed to explain the reason of increasing of burning rate at low pressure (<1.96MPa) and decreasing at high pressure (>1.96MPa). |
