Abstract

In order to reduce resistance of the rocket depth charge in the water, resistance characteristics of the rocket depth in the water were studied with Fluent. The relationship between submergence speed as well as corresponding bubble state of rocket depth charge and resistance characteristics was obtained and analyzed. The results show that resistance caused by pressure difference is the main part of resistance components. With the supercavity, when the speed decreases, resistance caused by pressure difference increases, and viscous resistance decreases, and the resistance coefficient increases gradually. After the supercavity collapses, resistance caused by pressure difference decreases, and viscous resistance increases, and the resistance coefficient decreases rapidly. Comparing the simulation data with the data of water tunnel experiment, the two are essentially the same.

Key words： rocket depth charge; resistance characteristics; Fluent
