Observation and Evaluation of Al Droplets from Propellant

抄録

We observed Al droplets near propellant surface with the CMOS camera, achieved the observation of Al droplets near propellant surface through 1MPa to 8MPa and measured the diameter of Al droplets near the burning propellant surface. We also observed the propellant section cut by the microtome and measure the size of Al droplets in the pockets. We investigated the relationship between the diameter of Al droplets near the burning propellant surface and the pocket sizes. When the direction of acceleration is the same to the burning direction, the acceleration affect the diameter of Al droplets, and the size of Al droplets become larger than those under static conditions.
