Abstract:
The influence of an acceleration field on the combustion rate of a composite solid propellant when directed normally and into the burning surface was recorded by high speed cinematography. One-half to one-inch long propellant strands with 14-in by 14-in cross sections were burned and photographed at pressures of 200 psi and 500 psi while subjected to normal acceleration fields of 0 g and 75 g. Aluminized propellants were primarily utilized in this investigation however, the experimental apparatus and the techniques used proved suitable for general propellant studies. Propellants burning in acceleration fields of 0 g and 75 g were successfully filmed at frame rates of 4500 pictures per second. The designed magnification factor and the quality of the motion pictures produced provided an optical definition of particle sizes to 100 microns. This film resolution allowed an optical analysis of the acceleration effects on propellant burning rates. Author
