Abstract

A photographic system is described which records the near surface combustion of a solid rocket propellant burning in an acceleration field. Strands of propellant which contain aluminum powder were photographed while burning in a pressure vessel (bomb) which is mounted on a centrifuge table. A lens and series of mirrors magnify and relay the image from the spinning bomb to a rotating prism camera. The trajectories of burning aluminum particles (50-1000μ in diameter) were investigated at framing rates of 4000 pps and unity magnification. A description of the centrifuge and photographic system is presented along with representative results derived from the film analysis.
