Experimental determination of the drag-force coefficient through soda-bottle rocket launching

Abstract

This paper’s main objective is to measure the drag-force coefficient for low-velocity movements of pressurized-air-water soda-bottle rockets. This is performed via two types of flights, namely vertical fall and inclined launch. The determined values are k = (0.05 ± 0.02)s-1 for the vertical fall and k = (0.03 ± 0.02)s-1 for the inclined motion.
